The item is working with a majority of devices. I was able to connect it in TX mode to many BT speakers and headphones, including the Steelseries Arctis Nova 7x. I however need to mention two things. 1. In RX mode, the device cannot connect to an Apple Watch Ultra 2. As a blind person recording demos, I was hoping to be able to use this RX TX adapter to be able to send the sound of my Apple Watch to a mixer, so VoiceOver can be heard in the recordong. The Apple Watch sees the device, however when trying to connect, the Apple Watch returns a message saying to make sure that the device is available. So, for someone who would like to play music on an Apple Watch and listen to it in a car with an Aux port, this won't work. Pairing an Apple Watch works fine with other RX/TX adapter like my old Aluratek ABC01F, but not with this one. Is it caused by the microphone? Who knows. 2. In RX mode, the device provides clear vocal indications, which is awesome for a blind person. If I may suggest, in TX mode, for someone like me who cannot see the light, it is really hard to know when the device is on, off, or in pairing mode. Adding haptic feedback can be really helpful to manage connection in the TX mode.
