I've had the Nexus 7 for a couple of weeks now.
Ventured out and purchased a bluetooth headset. I paired it to my cell phone and it works perfectly - no trouble with sound quality or any other issues.
However, the Nexus 7 is a different story. The headset paired up fine - but that is about the extent of it.
I have Skype installed along with the 3CX softphone. None of them will push the audio through the headset.
Reading another forum, someone mentioned downloading an app called BT mono. It allows you to go in and turn on or off the audio pushing to the headset - no matter what it is.
So I started some music in "Play Music" and then hit the "On" button in BT mono. After just a short pause, the music was then pushed to the headset instead of through the internal speakers. But, the music was cutting in and out and there was a bad amount of static to it.
Android is used on this tablet - as it is a vast array of phones. So why is BT so unreliable with this tablet versus others? Like I said, the headset works just fine with my Samsung phone (just a flip-phone that isn't running Android or anything fancy).
Not sure if anyone else has had any luck getting a headset to work. My primary purpose is to use this with my VoIP softphone app on the tablet - but it simply isn't working.
