### ⭐⭐⭐⭐⭐ Works

It work perfectly! I can use any headset for my zoom call

### ⭐⭐⭐⭐⭐ perfect adaptor
*by B***R on 26 July 2025*

Does what it says to do

### ⭐⭐⭐⭐ Reasonable build quality.
*by A***1 on 10 September 2025*

Does what it says on the tin. Occasionally, it may struggle to reconnect to headset if headset connects to another device. Just as well, it may miss connecting to the strongest signal and pairs with other audio devices in vicinity (it connected to my soundbar in the next room, but that may be anecdotal). Having said that, it works flawless 99% of time, it works great and is fairly easy to live with. It remembers last connected device and reconnects when plugged back in. Once connected, keeps connected for hours. Perfect to bypass bluetooth device restrictions in particular work device scenarios.
