For most TV listeners, the Avantree Audikast 3 is my best overall pick because it is designed to send TV audio to two Bluetooth headphones. The SOOMFON aptX-LL stands out for shoppers prioritizing lip-sync support, while the UGREEN Bluetooth 6.0 adapter better suits people who also want a travel-ready device. The main tradeoffs are TV connection compatibility, audio delay, two-listener support, and whether you need a transmitter only or a transmitter-receiver combo. I compare all 14 options by those differences so you can match an adapter to your TV and headphones. Read on for the full breakdown and buying advice.

Key Takeaways
- The Avantree Audikast 3 earns the overall lead for a TV-first setup built around sending audio to two headphones, rather than splitting attention across travel and receiver features.
- The two SOOMFON TV transmitters serve different priorities: the aptX-LL model foregrounds low-latency support, while the standard 5.3 model is a simpler two-headphone option.
- Several products combine transmitter and receiver modes, but that extra flexibility matters only if you also plan to use Bluetooth audio with wired speakers, a car stereo, or another source.
- Airplane-focused picks such as Avantree Relay, Twelve South AirFly SE, and UGREEN emphasize portable use; buyers should check TV inputs and power needs before treating them as living-room replacements.
- Product titles often promise two-headphone pairing, but results depend on compatible codecs and headphones; confirming both the adapter and headset support the same features can matter more than the Bluetooth version number.

More Details on Our Top Picks
Avantree Audikast 3 Bluetooth TV Transmitter for 2 Headphones
The Audikast 3 is a focused home-TV pick: it sends audio to two Bluetooth headphones at once, so two people can watch together without turning up the television. Optical and 3.5mm inputs suit TVs with conventional audio outputs, while aptX-Adaptive is intended to reduce lip-sync delay with compatible headphones. Built-in volume controls also make adjustments easier without reaching for the TV menu. Compared with the more input-flexible 1Mii Bluetooth 5.3 Transmitter, this model lists only optical and AUX connections, but its straightforward setup and 24-month warranty may appeal to buyers who want a dedicated TV transmitter. The tradeoff is firm: HDMI-only TVs are out, and optical use requires the TV audio setting to be PCM. It also needs a wired setup rather than offering battery-powered portability.
Pros:- Streams to two Bluetooth headphones simultaneously
- Supports aptX-Adaptive for reduced latency with compatible headphones
- Optical and 3.5mm AUX inputs fit common TV audio outputs
- Built-in volume controls and a 24-month warranty
Cons:- Does not connect to HDMI-only TVs
- Optical output requires the TV to be set to PCM
- Wired setup limits portability
Best for: Households with an optical- or AUX-output TV who want two viewers to use Bluetooth headphones simultaneously.
Not ideal for: Owners of HDMI-only TVs, or anyone who wants a battery-powered adapter for travel.
- Bluetooth version:5.3
- Inputs:Optical (TOSLINK) and 3.5mm AUX
- Supported standard:aptX-Adaptive
- Simultaneous headphones:2
- Range:Up to 100 feet
- Power source:Corded electric
- Weight:0.16 kg
- Warranty:24 months
Our verdict“Choose the Audikast 3 for shared, low-delay listening at home if your TV has optical or AUX audio output.”
2026 Upgrade Pro Bluetooth 6.0 Transmitter Receiver – 2-in-1 Adapter
For someone who wants one adapter for the TV and a travel bag, this Bluetooth 6.0 2-in-1 model offers more flexibility than the TV-focused Avantree Audikast 3. Its transmitter and receiver modes let it send TV audio to headphones or receive audio from a compatible source, while 20-plus hours of battery life and USB-C charging make it less dependent on a nearby power outlet. The product data also lists dual-device connections, a useful option for sharing audio. The compromise is limited detail about its physical size and weight, plus no specified TV input connection, so buyers should confirm that their TV’s output matches before choosing it. It is also not intended for live music, instruments, karaoke, or Bluetooth hearing aids. This is the more versatile pick, but the Audikast 3 provides clearer TV-specific input details.
Pros:- Transmitter and receiver modes extend use beyond the TV
- More than 20 hours of stated battery life
- USB-C charging supports convenient recharging
- Supports dual-device connections for shared audio
Cons:- TV input connections are not specified in the supplied product details
- Size and weight are not provided, making portability harder to judge
- Not compatible with live music, instruments, karaoke, or Bluetooth hearing aids
Best for: Travelers and multi-device households who want a rechargeable adapter that can transmit or receive audio.
Not ideal for: Buyers who need clearly specified optical or RCA TV inputs, or users of Bluetooth hearing aids and live-music equipment.
- Bluetooth version:6.0
- Modes:Transmitter and receiver
- Battery life:20+ hours
- Charging port:USB-C
- Connections:Dual-device connection support
- Compatibility:TV, smartphone, tablet, computer, headphones, and speakers
- Enclosure material:ABS
- Color:Black
Our verdict“Pick this model if rechargeable TX/RX flexibility matters more than the Audikast 3’s clearly listed TV inputs.”
1Mii Bluetooth 5.3 Transmitter for TV to 2 Wireless Headphones/Speakers
The 1Mii earns its place for households whose TV or PC setup calls for more than one kind of audio connection. Its optical, AUX, and RCA inputs cover more output types than the Avantree Audikast 3, and it can send audio to two headphones or speakers at the same time. The listed aptX Adaptive, aptX Low Latency, and aptX HD support gives buyers more codec options, though low delay depends on the receiving headphones supporting a matching standard. A display and straightforward controls help with setup, while the stated 100-foot range suits larger rooms. Unlike the battery-powered Bluetooth 6.0 2-in-1, this 1Mii requires USB power, so it is best treated as a stationary adapter. It also does not support hearing aids, and codec mismatch can leave audio out of sync.
Pros:- Optical, AUX, and RCA inputs support a broad range of audio setups
- Streams to two headphones or speakers simultaneously
- Supports aptX Adaptive, aptX Low Latency, aptX HD, and SBC
- Stated range of up to 100 feet and an easy-to-read display
Cons:- Requires an external 5V/1A USB power source
- No built-in battery for portable use
- Audio delay may occur when the headphones and transmitter lack matching codec support
Best for: TV and PC owners who need optical, AUX, or RCA input options and want to share audio with a second listener.
Not ideal for: Travelers seeking a battery-powered adapter, or hearing-aid users and buyers without compatible low-latency headphones.
- Bluetooth version:5.3
- Inputs:Optical, AUX, and RCA
- Supported codecs:aptX Adaptive, aptX Low Latency, aptX HD, SBC
- Simultaneous connections:2 headphones or speakers
- Range:Up to 100 ft / 30 m
- Power:5V/1A USB power adapter required
- Enclosure material:ABS
- Color:Black
Our verdict“Choose the 1Mii if input flexibility and dual-listener TV audio matter more than having a rechargeable, portable transmitter.”
Bluetooth 5.3 Aux Adapter for Car, Bluetooth Transmitter for TV
At just 11 g and 64 × 37 × 12 mm, this AUX adapter is the most pocketable choice in this group. It can send audio from a compatible TV’s 3.5mm output to Bluetooth headphones, and its six-hour battery makes it usable away from a wall outlet. That portability sets it apart from the corded Avantree Audikast 3, but the tradeoff is a much narrower TV setup: it has one AUX port, with no optical or RCA input listed, and the supplied details do not mention two-headphone transmission. The stated 10-meter connection range is also shorter than the 100-foot claims for the Audikast 3 and 1Mii transmitter. Buyers should note that it cannot be used while charging, so it is less suited to long viewing sessions than a powered home transmitter.
Pros:- Compact 64 × 37 × 12 mm body weighs 11 g
- Six hours of stated battery life for use away from an outlet
- Bluetooth 5.3 connection with a stated range of 10 meters
- Can also connect with listed cars, speakers, stereo systems, laptops, and radios
Cons:- One AUX port; optical and RCA inputs are not listed
- Cannot be used while charging
- Six-hour battery life and 10-meter range are less suited to long-distance home listening
Best for: AUX-equipped TV owners who want a lightweight adapter for short viewing sessions or occasional travel.
Not ideal for: People who need optical or RCA TV connections, extended all-evening use, or simultaneous audio for two headphones.
- Bluetooth version:5.3
- Port:One AUX port
- Battery capacity:250 mAh
- Battery life:Up to 6 hours
- Standby time:Up to 60 days
- Charging time:2 hours
- Dimensions:64 × 37 × 12 mm
- Weight:11 g
Our verdict“Choose this compact adapter for an AUX-only TV and portable listening, but use a powered model like the Audikast 3 for longer shared sessions.”
Bluetooth 6.0 Transmitter Receiver – Airplane/TV/Gym Wireless Audio Adapter
This adapter stands out for buyers who want a rechargeable TX/RX unit that can move between the TV, gym equipment, and airplane audio. Its 24-hour battery life and USB-C fast charging give it a longer portable run time than the Bluetooth 5.3 AUX adapter, which is listed for six hours and cannot be used while charging. The alloy and ceramic-glass build also sets it apart from the ABS-bodied 2026 Upgrade Pro, though that material choice adds a premium feel rather than improving TV compatibility. It includes 3.5mm audio and RCA ports, but the product data does not specify optical input, so buyers with optical-only TVs should check their connection needs. Low delay depends on headphone codec support, and pairing may be less smooth if earbuds remain connected elsewhere.
Pros:- 24-hour stated battery life with USB-C fast charging
- 3.5mm and RCA ports support multiple audio sources
- TX/RX functionality suits TV, travel, and gym use
- Alloy and ceramic-glass construction weighs 50 g
Cons:- Optical input is not listed, limiting fit with some TVs
- Low-latency performance depends on compatible headphone codecs
- Earbuds may need to be disconnected from other devices for stable pairing
Best for: Frequent travelers and home listeners who want a durable, rechargeable adapter for 3.5mm or RCA audio sources.
Not ideal for: Owners of optical-only TVs, or anyone whose headphones lack compatible low-latency codec support and who needs tightly synchronized dialogue.
- Bluetooth version:6.0
- Modes:Transmitter and receiver
- Ports:3.5mm audio and RCA
- Supported standards:AAC, SBC, aptX Low Latency
- Battery life:Up to 24 hours
- Charging:USB-C fast charging; 1.5 hours stated
- Build material:Aerospace-grade alloy and ceramic glass
- Weight:50 g
- Battery:1.5 watt-hours, lithium-polymer
Our verdict“Choose this model for a durable, long-running portable transmitter with 3.5mm or RCA connections, not for an optical-only TV.”
1Mii B06TX Bluetooth 5.3 Transmitter for TV to 2 Wireless Headphones/Speakers
The 1Mii B06TX is the clearest fit here for a TV that stays in one place and has more than one kind of audio output. Optical, coaxial, RCA, and 3.5mm inputs make it easier to match older and newer televisions than the UGREEN Airplane Bluetooth 6.0, which accepts only 3.5mm AUX. It can send audio to two headphones or speakers, useful for watching together, while its dual antennas and aptX Low Latency support are aimed at reducing lip-sync lag. That benefit depends on the receiving headphones also supporting aptX Low Latency; ordinary Bluetooth headphones may still introduce delay. Unlike the UGREEN and Ultra Pro adapters, this is a transmitter only, so it cannot receive audio from a phone or stereo. Its broad TV connections matter more than portability, but the one-year warranty is shorter than SOOMFON’s two years.
Pros:- Optical, coaxial, RCA, and 3.5mm inputs suit a wider range of TVs than AUX-only adapters.
- Connects to two Bluetooth headphones or speakers at once for shared listening.
- Dual antennas and aptX Low Latency support target longer-range, better-synchronized TV audio.
- Plug-and-play setup and volume control keep day-to-day use straightforward.
Cons:- Transmitter-only design cannot receive audio from a phone or other Bluetooth source.
- Low-latency performance depends on compatible aptX Low Latency headphones or speakers.
- One-year warranty is shorter than the SOOMFON’s stated two-year coverage.
Best for: Households with a stationary TV, varied audio outputs, and two compatible Bluetooth headphones for shared listening.
Not ideal for: Travelers or buyers who want one adapter for both sending and receiving audio, or who use headphones without aptX Low Latency and are especially sensitive to lip-sync delay.
- Model:B06TX
- Bluetooth version:5.3
- Audio inputs:Optical, coaxial, RCA, 3.5mm
- Device connections:Up to 2 headphones or speakers
- Low-latency support:aptX Low Latency
- Antenna:Dual antenna design
- Additional audio support:aptX HD
- Warranty:1 year
Our verdict“Choose the B06TX for a home TV with varied audio outputs and two compatible listeners; skip it if you need a portable receiver or guaranteed low delay with standard Bluetooth headphones.”
UGREEN Airplane Bluetooth 6.0 Transmitter Receiver for 2 AirPods or Headphones, 2-in-1 Wireless Bluetooth Adapter with 3.5mm AUX Jack
The UGREEN Airplane Bluetooth 6.0 is the versatile pick for someone who wants a single adapter for a TV’s headphone jack, airplane audio, and occasional Bluetooth receiving. Its transmitter/receiver modes set it apart from the transmitter-only 1Mii B06TX, while support for two headphones gives couples a way to share a wired source. The tradeoff for that travel flexibility is a 3.5mm AUX-only input: unlike the 1Mii, SOOMFON, or Ultra Pro, it cannot connect directly through optical or RCA. Its stated 10-meter range suits a nearby TV or seat, rather than roaming far around a home. Up to 18 hours of battery life supports extended trips, and the built-in microphone adds call use, though model compatibility has limits: the listing excludes AirPods Pro 2, AirPods 3, and AirPods 4, and iPhones may require manual reconnection.
Pros:- Transmitter and receiver modes cover more uses than the transmitter-only 1Mii B06TX.
- Pairs with up to two headphones for shared listening from a 3.5mm source.
- Up to 18 hours of battery life suits extended trips and listening sessions.
- Built-in microphone supports hands-free calls in compatible setups.
Cons:- 3.5mm AUX is the only listed input, excluding TVs that lack a headphone jack.
- The listing states incompatibility with AirPods Pro 2, AirPods 3, and AirPods 4.
- iPhones may require manual reconnection, and the 10-meter range is shorter than the stated maximum for SOOMFON.
Best for: Frequent travelers and small-space TV viewers who need both transmitter and receiver modes, use a 3.5mm jack, and want to share audio between two headphones.
Not ideal for: Owners of TVs with only optical or RCA output, users of the listed incompatible AirPods models, or anyone seeking a plug-in, battery-free home transmitter.
- Bluetooth version:6.0
- Modes:Transmitter and receiver
- Input:3.5mm AUX
- Battery life:Up to 18 hours
- Transmission range:10 meters
- Simultaneous headphones:Up to 2
- Microphone:Built in
- Power:1 included lithium metal battery
Our verdict“Pick the UGREEN if you want a rechargeable travel adapter that can transmit or receive audio through AUX, but choose a multi-input home unit for optical or RCA TV connections.”
Ultra Pro Bluetooth Transmitter Receiver Wireless Adapter for Airplane and TV
The Ultra Pro combines the two traits that can make a TV adapter easier to reuse: a lipstick-sized body and transmitter/receiver modes. For TV listening, it supports two devices at once and includes AUX and RCA inputs, giving it more home-audio flexibility than the AUX-only UGREEN. Its aptX Low Latency support is intended to keep picture and sound better aligned, but the headphones must support the same codec for that advantage to apply. A stated 20-hour battery life and USB-C charging also make it practical to move between a television and travel gear. Compared with the 1Mii B06TX, Ultra Pro adds receiver mode and portability, but gives up optical and coaxial inputs. The listing also says performance is best with line of sight and excludes Bluetooth hearing aids and 2.4G sync devices, so it is not a universal fit.
Pros:- Transmitter and receiver modes make it more reusable than the transmitter-only 1Mii B06TX.
- Connects to two devices simultaneously for shared TV listening.
- AUX and RCA inputs cover more home audio connections than the UGREEN’s AUX-only input.
- USB-C charging and a stated 20-hour battery life support portable use.
Cons:- No optical or coaxial input, unlike the 1Mii B06TX and SOOMFON.
- aptX Low Latency benefit requires compatible headphones or earbuds.
- Optimal range depends on line of sight, and Bluetooth hearing aids and 2.4G sync devices are listed as incompatible.
Best for: People who want one small, rechargeable adapter for a TV with AUX or RCA output and for travel, including occasional Bluetooth receiving.
Not ideal for: TV owners who need optical or coaxial input, listeners using Bluetooth hearing aids or 2.4G sync devices, or buyers who prefer a fixed, battery-free adapter.
- Bluetooth version:5.4
- Modes:Transmitter and receiver
- Inputs:3.5mm AUX, RCA
- Simultaneous connections:Up to 2 devices
- Supported codecs:AAC, SBC, aptX Low Latency
- Battery life:20 hours
- Charging:USB-C; 2 hours to full charge
- Range:33 feet
- Dimensions and weight:Lipstick-sized; 0.09 kg
Our verdict“Choose the Ultra Pro for compact dual-mode use with an AUX- or RCA-equipped TV, but look elsewhere if your television needs optical input.”
SOOMFON Bluetooth 5.3 Transmitter Receiver for TV to 2 Headphones
The SOOMFON Bluetooth 5.3 makes TV listening easier to manage from the adapter itself: its LCD display and volume controls give a clearer view of operation than the more travel-focused UGREEN or Twelve South AirFly SE. It also supports two headphones and accepts optical, AUX, and RCA connections, so it suits a shared home TV better than AUX-only adapters. The stated range reaches up to 30 meters, which may help when listeners move around the room or nearby home, though actual performance depends on the setup. Compared with the 1Mii B06TX, SOOMFON adds receiver mode and a longer stated warranty, while the 1Mii lists coaxial input and aptX Low Latency support. SOOMFON’s listing does not specify a low-latency codec, so buyers sensitive to lip-sync should check compatibility rather than assume it.
Pros:- Optical, AUX, and RCA inputs support a range of TV connections.
- LCD display and volume controls make adapter status easier to check than on simple travel units.
- Supports two Bluetooth headphone connections for shared listening.
- Stated range of up to 30 meters and a two-year warranty suit a home setup.
Cons:- Coaxial input and aptX Low Latency support are not listed, unlike the 1Mii B06TX.
- Volume control is not independent for the two connected devices.
- No microphone, and devices requiring a Bluetooth pairing PIN are unsupported.
Best for: Home viewers who want an LCD-equipped adapter for sharing TV audio between two headphones and whose television has optical, AUX, or RCA output.
Not ideal for: Buyers who need coaxial input, rely on aptX Low Latency for synchronized dialogue, need a microphone, or use Bluetooth devices that require a PIN to pair.
- Bluetooth version:5.3
- Modes:Transmitter and receiver
- TV audio inputs:Optical, AUX, RCA
- Simultaneous headphones:Up to 2
- Range:10–30 meters
- Display:LCD
- Listed compatible sources:TV, PC, MP3 players
- Warranty:2 years
Our verdict“Choose SOOMFON if you value a visible display, multi-input TV support, and two-headphone sharing more than specified low-latency performance.”
Twelve South AirFly SE Bluetooth Wireless Audio Transmitter Adapter, White
The Twelve South AirFly SE is the straightforward choice when a TV or other source has a 3.5mm audio jack and the goal is simply to send sound to wireless headphones. Its small, 13.61-gram design and more than 20 hours of stated battery life make it easy to carry between a TV, gym equipment, and airplane audio. That portability is its advantage over the larger home-oriented 1Mii B06TX, but the AirFly SE is transmitter-only and has no listed dual-headphone support, so it is less suited to shared viewing than the 1Mii or SOOMFON. It also lacks the optical and RCA connections offered by those TV-focused alternatives. Bluetooth 5.2 and aptX support are listed, but aptX Low Latency is not; buyers sensitive to lip-sync should not assume the AirFly SE will match the B06TX’s stated low-latency feature.
Pros:- Lightweight 13.61-gram build is easier to carry than home-focused adapters such as the 1Mii B06TX.
- More than 20 hours of stated battery life supports extended travel and listening.
- Quick pairing and simple controls suit buyers who want a basic transmitter.
- Can be used while charging.
Cons:- 3.5mm jack is the only listed audio input; there is no optical or RCA connection.
- Transmitter-only design and no listed dual-device pairing limit shared listening and reuse.
- aptX is listed, but aptX Low Latency is not, so synchronized TV dialogue is not specified.
Best for: Solo listeners who want a lightweight adapter for a TV or other source with a 3.5mm jack and also plan to use it for travel or gym audio.
Not ideal for: Two-person TV watching, televisions without a 3.5mm output, or buyers who need receiver mode, optical/RCA inputs, or explicitly listed aptX Low Latency support.
- Model:AirFly SE
- Bluetooth version:5.2
- Operation:Transmitter
- Audio connection:3.5mm audio jack
- Supported standards:Bluetooth 5.2, aptX, SBC
- Battery life:20+ hours
- Weight:13.61 g
- Dimensions:0.38 × 1.25 × 1.75 inches
- Power:Battery powered; usable while charging
Our verdict“Pick the AirFly SE for lightweight, solo headphone listening from a 3.5mm TV output, but choose a multi-input dual-headphone adapter for shared home viewing.”
Bluetooth 5.3 Transmitter Receiver for TV and Wireless Headphones, 2-in-1 Bluetooth Adapter
This model makes sense for someone who wants one compact adapter for TV listening and occasional Bluetooth receiving, without extra controls or features to learn. Its 3.5mm connection and plug-and-play setup keep installation straightforward on compatible TVs, while Bluetooth 5.3 and up to 8 hours in transmitter mode cover a typical evening of viewing. It can also run up to 10 hours as a receiver, which gives it more flexibility than the Avantree Relay, a transmitter-only travel option with longer stated battery life. The tradeoff is a narrower TV fit: this adapter is limited to 3.5mm, and some sets need a separate RCA cable. I would choose the 1Mii Bluetooth 5.3 Transmitter Receiver instead when RCA connectivity or a smaller, lighter body matters more.
Pros:- Transmitter and receiver modes let it serve more than TV headphone use.
- Bluetooth 5.3 supports a stable wireless connection with low power consumption.
- Up to 8 hours of stated battery life in transmitter mode.
- Plug-and-play setup avoids a complicated installation.
Cons:- 3.5mm-only connectivity can exclude TVs without a compatible analog output.
- Some TV setups require a separate RCA cable.
- Not intended for live music, instruments, or karaoke use.
Best for: TV owners with a 3.5mm headphone output who want a basic transmitter that can also receive Bluetooth audio from another device.
Not ideal for: Viewers whose TVs only provide RCA or digital audio outputs, or anyone who needs shared listening for two headphones.
- Model:BT-6
- Bluetooth version:5.3
- Modes:Transmitter and receiver
- Audio connection:3.5mm audio jack
- Battery life:Up to 8 hours in TX mode; up to 10 hours in RX mode
- Charge time:2 hours
- Battery type:Lithium-ion
- Warranty:1 year
Our verdict“Choose this for uncomplicated 3.5mm TV listening with the added option of receiver mode, but skip it if your TV needs RCA or digital connectivity.”
Avantree Relay – Bluetooth Adapter for Airplane Headphones
The Relay is the clearest choice here when the priority is sharing one audio source with two Bluetooth headphones, especially on a plane. Its dual-link design and up to 25 hours of battery life suit long journeys better than the shorter-running BT-6, while onboard buttons and plug-and-play operation keep setup simple. aptX support is listed, including aptX Adaptive, but the supplied details do not identify aptX Low Latency; for TV viewing where lip-sync is the main concern, the SOOMFON aptX-LL Bluetooth 5.3 Transmitter Receiver is a more targeted option. The Relay is also transmitter-only, so it cannot receive audio or handle calls. Its 3.5mm input may require an adapter with newer devices, and its airplane-first design makes it less flexible for a mixed home setup.
Pros:- Dual-link support connects two headphones to one audio source.
- Up to 25 hours of battery life suits extended travel.
- Plug-and-play setup with onboard button controls.
- aptX Adaptive support is listed for compatible headphones.
Cons:- Transmitter-only operation rules out receiving audio from a phone or other Bluetooth source.
- A 3.5mm audio jack limits use with devices that lack an analog output.
- No microphone or call functionality.
Best for: Travelers who want two people to listen to the same airplane or other 3.5mm audio source on separate Bluetooth headphones.
Not ideal for: TV viewers prioritizing explicitly specified aptX Low Latency, or buyers who need receiver mode, microphone support, or a digital TV connection.
- Device type:Bluetooth transmitter
- Dual connection:Connects two headphones
- Supported features:aptX Adaptive
- Battery life:Up to 25 hours
- Charge time:2 hours
- Battery type:Lithium-polymer
- Audio connection:3.5mm audio jack
- Warranty:12 months, extendable to 24 months with registration
Our verdict“Pick the Relay for long trips and shared listening on two headphones, not for a flexible home transmitter-receiver or a TV setup that specifically needs aptX Low Latency.”
SOOMFON aptX-LL Bluetooth 5.3 Transmitter Receiver for TV to 2 Headphones
For TV and gaming, the SOOMFON’s defining advantage is its stated aptX Low Latency support, aimed at keeping dialogue and on-screen action better synchronized with compatible headphones. The built-in LCD also makes the mode and connection status easier to check than on the simpler BT-6. It works as both a transmitter and receiver, supports two connections, and lists up to 23 hours in TX mode, so it can move from a home TV to travel use. That flexibility comes with limits: aptX-LL benefits depend on compatible headphones, Dolby audio is not supported, and two connected listeners cannot adjust volume independently. The 1Mii Bluetooth 5.3 Transmitter Receiver is a smaller alternative with RCA listed, but this SOOMFON is the more feature-forward pick when latency and display feedback matter most.
Pros:- aptX Low Latency support targets better audio-video synchronization with compatible headphones.

1Mii Bluetooth 5.3 Transmitter Receiver for TV and Headphones
At just 20 g and about 1.96 inches long, this 1Mii is the lineup’s most clearly specified pocketable pick. Its combination of 3.5mm and RCA connectivity makes it easier to match with older TV audio outputs than the 3.5mm-only BT-6, while transmitter and receiver modes add flexibility for other audio gear. The listing also specifies aptX Low Latency and dual-link support, useful features for compatible headphones and shared listening. Its stated 18-hour battery life is shorter than the SOOMFON’s TX figure and well below the Avantree Relay’s, though the 1Mii is more adaptable than that transmitter-only travel model. It still relies on battery power, and it does not list digital optical connectivity, so it may not fit TVs that lack analog outputs.
Pros:- Very light at 20 g and compact enough for travel.
- 3.5mm and RCA connectivity broadens compatibility with analog TV outputs.
- Transmitter and receiver modes support more than TV headphone use.
- aptX Low Latency and dual-link support are listed.
Cons:- Battery-powered operation requires charging before use.
- No optical or HDMI audio connection is listed.
- Its 18-hour battery life is shorter than the SOOMFON and Avantree Relay figures.
Best for: TV owners who want a lightweight adapter for analog 3.5mm or RCA outputs and may also use it with other audio devices.
Not ideal for: People with TVs that provide only optical or HDMI audio, or travelers who need the longest listed battery life for two-headphone sharing.
- Bluetooth version:5.3
- Modes:Transmitter and receiver
- Connectivity:3.5mm and RCA
- Supported audio feature:aptX Low Latency
- Dual-link:Supported
- Battery life:Up to 18 hours
- Charging time:2 hours
- Dimensions:1.96 × 1.37 × 0.31 inches

Our verdict“Choose this 1Mii for a small analog-output adapter with both operating modes, but look elsewhere if your TV needs digital audio or you need maximum battery runtime.”
How We Picked
I ranked these Bluetooth TV adapters for headphones by how clearly each product fits a television setup: usable audio inputs, straightforward pairing, support for one or two listeners, and features that can help keep dialogue synchronized. I also weighed whether a model is primarily a TV transmitter or a travel-oriented adapter, since a compact airplane unit may be convenient but can be less suited to a permanent TV installation. Product names and stated features informed the comparison; I did not treat a larger Bluetooth version number as proof of better sound or range.
The order favors TV-specific usefulness first, then flexibility, portability, and ease of use. Models that explicitly target TV audio and two headphones rank ahead of general-purpose adapters when their feature set better matches shared viewing. A low-latency claim or transmitter-receiver mode can move a pick up for the right buyer, but neither outweighs input compatibility or a clear use case. Because listings can vary by version and bundle, buyers should confirm the exact ports, codec support, and included cables for the model they select.
Factors to Consider When Choosing Bluetooth Tv Adapters For Headphones
Before choosing among these adapters, I would start with the TV and headphones you already own, not the adapter’s headline Bluetooth version. A useful match depends on the television’s available audio output, whether one or two people will listen, and how sensitive you are to dialogue delay. These checks can prevent a common mismatch: buying a capable adapter that cannot connect cleanly to the TV or pair as expected with the headphones.
Match the adapter to your TV’s audio outputs
Check the TV’s audio-out connections before shopping: many adapters use a 3.5 mm AUX jack, while some setups rely on optical audio or another output. A TV’s headphone jack, if present, may work differently from a line-level output, so check the TV manual and adapter instructions rather than assuming every port is interchangeable. If the TV has only an output that the adapter does not accept, you may need a separate converter, adding another box and more setup steps. Also check whether the adapter’s cable is included and long enough to reach a convenient position. For a fixed living-room setup, reliable connection and placement can matter more than a compact airplane design. I would choose the simplest supported connection path over buying extra features that do not solve an input mismatch.
Decide whether you need one or two headphone connections
Two-headphone support is useful for shared viewing, but it does not automatically mean every headset pair will behave identically. Some adapters pair with two devices yet may have limits on codec use, volume control, or synchronization when both are connected. If you usually watch alone, a single-listener setup may be simpler and can avoid paying attention to a feature you will rarely use. For two listeners, check whether each person can set headphone volume independently and whether the adapter supports the headsets’ Bluetooth profiles. It is also worth thinking about future use: a second pair of headphones from a different brand may not share the same low-latency codec. Choose dual pairing for a real household need, not just because the specification sounds more capable.
Treat low-latency support as a compatibility chain
Low-latency features can reduce the gap between spoken dialogue and the picture, but the adapter alone cannot control the whole chain. The headphones also need to support a compatible codec, and the TV’s audio processing can add delay before sound reaches the transmitter. A codec name in a product listing is not a guarantee that your existing headphones will use it. If lip sync is your main concern, check the codec on both devices and look for TV settings that adjust audio delay. For casual viewing or music, standard Bluetooth may be adequate; for dialogue-heavy programs, a codec mismatch can be frustrating. I would prioritize confirmed compatibility over Bluetooth generation when timing matters most.
Choose a TV transmitter or a 2-in-1 adapter
A transmitter sends sound from the TV to wireless headphones; a receiver does the reverse, taking Bluetooth audio and sending it to wired equipment. A 2-in-1 model can be handy if you also want to add Bluetooth to a car stereo or wired speaker, but switching modes can add controls and setup choices. Buyers who only need private TV listening may be better served by a TV-focused transmitter with clear pairing steps. Check how the device indicates its current mode, since a small switch or button sequence can be easy to misread. Also confirm whether it can remain powered during long viewing sessions or needs periodic charging. Pay for receiver mode only when you can name another device you plan to connect.
Separate travel convenience from permanent TV use
Airplane adapters are often small and designed around a 3.5 mm jack, making them easy to pack and connect to seatback entertainment systems. That same compact format may be less convenient beside a television if it lacks the input, power arrangement, or controls you want for everyday use. A built-in battery helps away from an outlet, while a TV-centered setup may benefit more from steady power and clear status indicators. Think about where the adapter will live and whether you will move it between devices often. If you want one adapter for a TV and travel, compare its input support and power method for both settings rather than relying on the word “portable.” A dedicated TV pick can be the simpler choice when home viewing is the main job.
Check setup details before choosing a feature-rich model
Product titles can make adapters sound similar even when their controls, cables, and operating modes differ. Before buying, verify what comes in the box, how pairing is started, and whether the device reconnects to previously paired headphones. A display or clear indicator lights can make setup easier, but a crowded set of controls may be unnecessary for someone who will leave the adapter connected. Consider whether you can operate it without reaching behind the TV, especially if pairing changes are likely. Keep the adapter’s placement in mind too: hiding it behind a cabinet may weaken the wireless path or make troubleshooting harder. A few minutes spent checking the manual and port list can save more effort than a feature you never use.
Frequently Asked Questions
Will any Bluetooth TV adapter work with my television?
No. The adapter needs an audio output that matches one of the TV’s supported inputs, such as AUX or optical, and some TVs may not provide the output you expect. Check the television manual for audio-out options and whether the selected port sends sound while internal speakers are active. Then compare that list with the adapter’s actual ports and included cables. If you need a separate converter, factor in the added connections and setup before choosing a model.
Can two people listen through headphones at the same time?
Some adapters in this roundup are specifically marketed for two headphone connections, but pairing two devices does not guarantee identical performance with every headset combination. Confirm that the adapter supports two simultaneous connections and check for any codec or volume-control limits. If both listeners care about lip sync, their headphones’ codec support matters too. For a household that shares viewing often, test compatibility with the actual headphone models before relying on dual pairing.
Will a Bluetooth adapter fix audio delay between dialogue and video?
It may reduce delay when the adapter and headphones share a supported low-latency codec, but it cannot promise perfect sync with every setup. The TV can add processing delay, and headphones without matching codec support may fall back to a different mode. Check both devices’ specifications and look for audio-delay adjustments in the TV menu. If dialogue sync is a high priority, a TV-focused low-latency model such as the SOOMFON aptX-LL is a more relevant starting point than an airplane adapter, but compatibility still decides the result.
Should I choose a transmitter-receiver model if I only watch TV?
Usually, a transmitter-only design is the more direct fit if sending TV audio to headphones is your sole use. A 2-in-1 adapter adds receiver mode for sending audio from a phone or other Bluetooth source to wired speakers, which can be useful in a second setup. That flexibility can also mean extra controls and more chances to select the wrong mode. I would choose a combo unit when you have a clear second use, not simply because it has more modes.
Are airplane Bluetooth adapters a good choice for a home television?
They can work when the TV provides a compatible audio output, but airplane-focused models are designed around portability and seatback connections rather than every living-room setup. Check their input type, power method, and whether they support the number of headphones you need. A battery-powered compact unit can suit someone who will move it between a TV and travel, while a TV-first adapter may be easier to leave connected at home. The right choice depends on which setting will get regular use.
Conclusion
For a dedicated shared-viewing setup, I would start with the Avantree Audikast 3 as the best overall option because its stated role centers on TV audio and two headphones. The 1Mii B06TX is my best-value direction for buyers who want a TV-focused two-headphone transmitter without needing travel-first extras, while the SOOMFON aptX-LL is the better fit for shoppers who have compatible headphones and place dialogue sync high on their list. Beginners should favor the model whose ports match the TV and whose pairing steps are clearest, rather than paying for receiver mode or advanced codec claims they cannot use. For travel, the UGREEN, Twelve South AirFly SE, or Avantree Relay may make more sense, subject to input and power compatibility. My final check would be the TV output, headphone codec support, and whether one or two listeners need to connect.
