Bluetooth 5.4 Transmitter & Receiver · 3.5 mm AUX
Listen to a wired TV through compatible wireless headphones, or stream your phone’s music to an AUX-equipped stereo. One compact adapter gives your existing audio equipment a new way to connect.
Two modes.
Two different jobs.
The switch changes which direction the audio travels. Choose one mode at a time; the adapter does not transmit and receive simultaneously.
TX · Send sound wirelessly
Use when the sound starts at equipment with an analogue output and you want wireless listening.
RX · Add Bluetooth to a stereo
Use when the sound starts on your phone and you want it played through existing wired audio equipment.

AUX IN and headphone OUT are different. A TV’s audio input cannot feed the transmitter. In receiver mode, connect to an amplifier, car stereo or powered speaker with an appropriate audio input.
Two headphones.
One shared programme.

TX: two listeners
Pair a second compatible headset so two people can hear the same source. Each headset’s buffering and volume controls may differ.
RX: two connected phones
Connect two source devices and take turns. Play from one phone at a time; this is not an audio mixer.
For a shared TV session, test your exact pair of headphones before settling in. Audio delay can vary between devices even when both receive the same programme.
From the living room
to the next departure.


Music in an older car
Select RX, connect to the car’s AUX input and select AUX on the stereo. Stream from a compatible phone without replacing the head unit.
TV and travel listening
Select TX and connect to a compatible headphone output. A dual-prong aircraft socket is not a direct fit; check the seat’s audio connection before travelling.
Not a direct digital-audio connection. There is no optical, HDMI ARC/eARC or USB-audio input. A separate suitable converter may be required for equipment without analogue audio; it is not included.
Match the role.
Then check the model.
Apple phones, tablets & headphones
Compatible iPhones and iPads can act as Bluetooth audio sources in RX mode. Headphone compatibility must be checked separately.
AirPods compatibility is model-specific; confirm your exact generation.Android phones & tablets
Compatible Galaxy and other Android devices can stream Bluetooth audio to the adapter in RX mode. No headphone jack is needed on the phone.
Connect the adapter’s 3.5 mm plug to the receiving stereo.Brand marks identify device families and do not imply universal compatibility or endorsement.
For TVs, PCs and projectors
TX requires a working analogue audio output. Select the correct output in the source’s sound settings. A USB socket alone is not enough.
For stereos and speakers
RX requires an appropriate analogue input. Passive loudspeakers need an amplifier; the adapter is not a speaker power amplifier.
Other buying limits: For musical instruments and live monitoring, use equipment designed for those applications. This is not a hearing-aid streamer, Bluetooth keyboard/mouse dongle, Wi-Fi adapter or wireless CarPlay/Android Auto adapter.
Know what the connection carries.
Bluetooth 5.4 audio connection
Send audio to compatible wireless headphones in TX mode, or receive phone audio for your stereo in RX mode.
Check codecs separately
Bluetooth version alone does not establish AAC, aptX, LDAC or LE Audio support. Check the supplied version’s specifications if a particular codec is essential.
Bluetooth 5.4 does not guarantee instant audio. Video lip-sync and game response depend on the complete setup. For timing-critical gaming or live monitoring, consider a wired connection.
Calls in receiver mode
The adapter has its own built-in microphone for compatible phone-call use in RX mode. Position it where your voice can reach it and check the phone’s audio routing.
TX is for listening
Do not expect a Bluetooth headset microphone to be sent back through a TV or console headphone socket. This is not a two-way gaming-chat adapter.
Set the mode.
Make the connection.

First headset · TX mode
Select TX and power on
Move the switch to TX and power on using the supplied instructions. Enter pairing mode before connecting your headphones.
Put the headset into pairing mode
Follow the headset’s instructions and keep it close to the adapter. A headset that is merely powered on may not be discoverable.
Confirm the link and connect the source
Confirm that the headset is connected. Insert the plug into the source’s 3.5 mm output, start audio and raise volume gradually.
Add a second headset in TX
Pair the first headset, then follow the supplied manual’s second-device pairing procedure. Check that both headsets are connected and receiving sound.
First phone · RX mode
Select RX and power on
Move the switch to RX, power on and enter pairing mode following the supplied instructions.
Select the adapter on your phone
Open your phone’s Bluetooth device list and select the adapter. Check its advertised pairing name in the supplied instructions.
Connect to the stereo’s AUX input
Select AUX on the stereo, start playback on the phone and adjust volume gradually.
Add a second phone in RX
Follow the supplied manual’s second-phone pairing procedure. Pause one phone before starting playback from the other.
Recharge. Reconnect. Go.

USB-C recharging
Recharge the internal battery before your next listening session. Follow the supplied manual’s charging guidance.
Portable listening
Move the adapter between compatible home, car and travel setups. Runtime depends on operating mode and use conditions.
Recharge through USB-C using a suitable USB power source. Keep the charging port dry, avoid bending the audio plug under load and switch the adapter off when packing it away.
What range should I expect?
Walls, a body blocking the signal, metal equipment and radio interference can reduce usable range. Keep the adapter near the listening area for a more dependable link.

Quick answers.
Less trial and error.
Why is it paired but silent?
Check the TX/RX switch, the direction of the wired audio socket and the selected sound output or AUX input. Start playback and check volume on both ends. Pairing confirms a Bluetooth connection, not that the source is sending audio.
Why will my AirPods not pair?
Check support for your exact AirPods generation. Put the earphones into pairing mode using Apple’s instructions and temporarily disconnect competing Bluetooth sources. Bluetooth 5.4 alone does not guarantee compatibility with every headset.
Can a TV use it without a headphone output?
Not directly if the TV only has digital outputs. You need a compatible analogue output or a separately selected digital-to-analogue audio solution. This adapter cannot plug into optical or HDMI ports.
Does it work on every aircraft?
No. It directly fits a single compatible 3.5 mm audio socket. Socket layouts and airline policies vary; dual-prong systems require an appropriate separate adapter.
Can it mix music from two phones?
No. RX dual pairing lets two sources stay connected, but only one phone’s music plays at a time.
Is there an aptX low-latency mode?
An aptX mode is not claimed in this description. Confirm the supplied version’s codec specification if this matters for your setup; Bluetooth 5.4 alone does not guarantee low-latency audio.
Can I use my headset microphone for console chat?
Do not rely on that setup. TX sends programme audio; it does not provide a Bluetooth-headset microphone return path to the source.
How can I troubleshoot unstable pairing?
Charge the adapter, place it close to the other device and check that the other device is in pairing mode. Disconnect competing Bluetooth connections. If needed, follow the reset procedure in the manual supplied with your unit and pair again.
What if I hear distortion or background noise?
Try moderate volume at the source and adjust the receiving equipment gradually. Ensure the plug is fully seated. Test a different audio source or AUX input to isolate where the noise begins.
How should I care for it?
Keep it dry and away from excessive heat. Do not twist or lever the plug in a socket. Stop using it if the battery swells or the housing is damaged. Set up car audio while parked.
Which Bluetooth version is supplied?
This UGREEN India listing is for the Bluetooth 5.4 version of UGREEN 80893. Use the instructions supplied with your unit for pairing controls, indicator patterns and charging details.
