I've got a Blueparrott B250-XT+ which is a pretty popular brand of "over the head" headset for truck drivers. I'm having trouble trying to connect to the android TS app with it. I am able to hear through it briefly before the sound goes back to the device audio automatically (Samsung galaxy S3 and Sony Xperia Z2 tablet ). The microphone does not work at all, only works through device mic. I've tried different settings in audio settings, but still not working. Headset works perfectly fine on Win 7 PC. I'm always on the road and hoping to get this problem resolved. Anyone else experience the same issue? Any suggestions? Thanks for any kind of help.
