It is nice and useful one. Great packing and enough instructions. You can simply change your Aux port to a great Bluetooth feature to enjoy music and audios.

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.

perfect for travelling. Was able to use it and freed me of wired headsets on a plane. Very convenient and easy to use

Don’t buy it the charge last about 3 hours and there is disconnection of sound for 4 to 5 seconds randomly.

My current TV set doesn't have (or doesn't expose) Bluetooth functionalities. This device was the perfect solution to connect my Bluetooth headsets to isolate myself from anything else happening in the room while watching Manchester City games!I tested it with a not-so-recent pair of Beats Studeio3 headsets, and it worked smoothly. I suggest charging the little device first, ensuring you can set your device on pairing mode, and then click on the device to start and complete the process.I will test it with machines at the gym even though media content on that devices not so cool. Other potential area of utilization is on a plane.

In the car as receiver they work as transmitter i tried many different devices, i followed instructions perfectly and the device simply doesn't transmit. Im returning them

Theres a delay when transmitting an audio. But if you are not an audio expert then it will be ok
