Audio Adapter Transmitter and Receiver

Good quality , usefull

I previously purchased this model in Malaysia from Ugreen's official store. It worked fine for a while, but one day, it suddenly stopped transmitting and receiving sound. The system itself remained functional, but the audio section failed. Today, I received the same model from Amazon and compared it to my previous one. There is a significant difference that makes me suspect this might be a counterfeit product. The build quality feels noticeably cheaper—tapping on the plastic casing produces a hollow sound, and when shaken, there is a rattling noise inside, raising concerns about its durability. Additionally, the TX/RX switch feels flimsy and lacks the sturdiness of the original. In terms of audio performance, it seems to work fine. Since the sound is digitally transmitted, I can't detect any major differences, though I'm unsure whether the battery life will be as good as before. Ultimately, I have no choice but to use it, but I can't shake the feeling that this is either a counterfeit product or that the manufacturer has downgraded the build quality. I'm still uncertain.

Hello! My use case is to get audio output from 3.5mm (qudelix 5k) transfered to my bluetooth headphones, and this device is make it super simple and convinient. Ideas is to use cheap wireless microphone to use in phone (android apps) calls and this thing is helped me. My current setup is: Phone --usb-- Qudelix5k -- 3.5mm output + 3.5mm input: 3.5mm output -- UgreenTX -- bluetooth -- headphones 3.5mm input -- 3.5mm hollyland lark m2 camera receiver -- air 2.4ghz -- microphone and as a result i have wireless headphones and microphone with excellent quality of sound in and out. thank you Ugreen!

One of the best devices I ever bought. Works perfectly . Clear voice. Battery last long time. Recharge it with type c. And if left it hanging it will take the shape of ur car.

Good for media but terrible for calls

Didn't really work for me. Returned it. I thought I was doing something wrong but it doesn't work with everything they have market it.

amazing and clear voice i love UGREEN products all of it is high quality products

Audio quality was pretty average, but disappointed because it keeps losing signals from my phone in the middle of the song.

Lo uso para escuchar la música del móvil en el coche, conectado siempre al cargador del coche y a la entrada RCA. Se enciende automáticamente cuando arranco el coche sin ningún problema, y en un segundo me avisa de que el teléfono se ha conectado por bluetooth. La música se escucha bien y nunca se me ha interrumpido la conexión al móvil.

funzionante e di qualità

This is a great product; it allows you to receive and transmit Bluetooth. I have used it both ways and it works great.

Seamless and easy to connect with any audio device which doesn't have a Bluetooth connection. There is no lag and output seems to be good enough. Its small and compact and the battery life is also fair enough.

I’ve been using the UGREEN Bluetooth Transmitter for a few years now, and it’s been an absolute game-changer—especially on flights. Pairing it with the inflight entertainment system gives me completely wireless freedom, and when coupled with a right-angle 3.5mm jack adaptor, it stays neatly tucked out of the way—even when getting in and out of my seat. Ease of Use: This transmitter couldn’t be easier to operate. It powers on quickly, pairs seamlessly with my Bluetooth headphones every time, and just works without fuss. Build Quality: As expected from UGREEN, the build is solid and premium. It’s compact, feels durable in hand, and fits snugly in travel bags without worry. Battery Life: The battery life is seriously impressive. It easily lasts through long-haul flights with plenty of charge left to spare—no need to top up mid-trip. Bluetooth Connection: The connection is rock solid. No drops, no lag, and the audio sync is spot-on—perfect for watching movies without lip-sync issues. Value for Money: For the performance and reliability it offers, this transmitter is incredible value. UGREEN continues to impress with high-quality, affordable tech that just works. If you travel frequently and want a reliable, wire-free way to enjoy inflight entertainment, this little device is a must-have. Highly recommended!
