it’s really amazing and very impressive product recommend to anyone

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.

Worked Once, Then Stopped ConnectingI was really hopeful about this adapter—it worked perfectly on the first leg of our trip with my Bose headset. Unfortunately, it never connected again after that. I tried troubleshooting, but no luck. Disappointed, especially since the return window has passed.

Working as expected !

It’s well made, I love the fact it’s transmitter and receiver together. I’m a traveler and less gadgets I have to bring with me and lighter it’s my baggage. This little Bluetooth TX-RX allows me to use it on the airplane to send music and movies sound to my AirPods Pro and to listen to music by connecting it to a rental car or hotels Tv. The price is good. I never had a connection problem. In the iPhone it even shows the battery level. It connect quickly and it even has an internal microphone when connected to a car stereo!!!! Money well spent.Ah! I almost forgot - USB-C connector to charge.I’m very happy.

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

Disappointed! Not working as expected! Volume is also too low when used with TV as a transmitter!!
