My new pair of Bluetooth headphones arrived today but when I paired them to my computer they will only play in mono, with Sound settings Test Speakers only showing in mono also. Also the quality of the sound being very poor when listening to music or a youtube stream. However they are fine with my television.

I am using a mini bluetooth usb adapter and the headphones are the Bluedio T2S. I am lead to believe that any usb adapter (like mine) should work fine with these.

Anybody got any ideas, would be much appreciated.


Edit: I've tried that a few times setting the profile from "HSP/HFP" to "A2DP Sink"

and it still doesn’t seem to function even if I repair the device, which I have tried numerous times.

In addition, when I setup the connection using the Bluetooth Manager app and set the Audio Profile to A2DP Sink I get "Failed to change profile to a2dp_sink".

  • Toggle modes - A2DP-HSP - and try again. Toggle again if it still doesn't work in stereo. Make sure you end up in the A2DP mode, of course. – user589808 Sep 25 '16 at 2:58
  • Hey Celtic. I'm not sure what you mean; to toggle in Sound settings or on the headphones? – Nectar Sep 25 '16 at 3:11
  • In sound settings. – user589808 Sep 25 '16 at 3:17
  • Neither A2DP Sink or HSP/HFP modes are making a difference. – Nectar Sep 25 '16 at 3:22

    I figured that already. HSP (HeadSet Profile) is Mono + Microphone whereas A2DP is Stereo (no Mic). You're already using the former and you want the latter. That's why I said Make sure you end up in the A2DP mode, of course. So, after toggling (a couple of times for good measure) and finally selecting A2DP it still shows Mono? If so, delete it and pair again. – user589808 Sep 25 '16 at 3:39
