Review on Sony XB950B1 Extra Bass Wireless Headphones: Enhanced Sound and App Control in Sleek Black Design by Qu Qui Qu (Cu C H in ᠌

A fatal flaw for me: it is impossible to have good sound quality AND a microphone at the same time. As far as I understand, this is a lack of all bluethooth headsets. The listening mode uses the A2DP profile with good sound quality. But if you need a microphone, the headphones switch to the HSP / HFP headset profile with an audio stream of about 64 kb / s. Just talking on the phone will do, but for long conversations / conferences via Skype or viber, this sound quality is very tiring. Wired headset for 200r gives incomparably better quality.
