Perfect Bluetooth headset (mono) for calls
I have used a Plantronics Voyager Pro HD with several phones from Samsung / Sony, but since I switched to the M8, all callers complain about my terrible voice sound. I have tried different options, nothing helped. With my BluebudsX (stereo) sound is perfect, caller say. But I want a mono headset for calls while driving or working.
I read many posts on bad BT-connectivity or quality, so my question now is:
Which BT-headset gives you perfect in-call-sound and fit, what is your experience? Any recommendations, any no-go's?
HTC One (M8), Stock Rom 4.4.2, Sense 6,0, rooted / unlocked / S-On
Samsung Galaxy Note 10.1, (8020) LTE/WiFi, Stock Rom 4.1.2,
