Z1 disconnects Bluetooth microphone

[Akihe]

I have new Z1 with the software updated to the latest release. When I connect my Jabra Wave+ headset it occurs frequently that the microphone will be muted. The time is varying from a few minutes to tens of minutes. I just need to reset the headset (off - on). Please, note that the speaker works all the time so the problem is unidirectional. I found also from Google Play an application called Xperia Bluetooth Media Fix to "reset the connection" and thus fix the problem but that does not help me. I also tested two different Jabra headsets but with the same results. 

Anything to do?

Sorry I can't help but I have something similar! When I call out sometimes I can hear who I called but they can't hear me! I drop the call and retry and everything is good. This only happens on the 1st attempt then all is good after that. Just a pain rather than a problem.
