I don't have any other Bluetooth headsets to compare this to, but have found the sound quality to be far better than any wired headset w/stub mic I have used. No one has any idea I'm not talking directly into the phone.As far as comfort goes, there is a way to twist the ear hook around the microphone so I was able to find a good balance point and have had no problems since fitting it correctly.Sound volume is a little weak.
