Pros: Good sound, buttons easy to pushCons: The ear piece is large and heavy and because it is not an inserted ear piece (like an ear bud), it just hangs from your ear pushing it out and competes with your eye glass frames. It is difficult to put on and never feels like it is secure or fits comfortably.I will be retiring this to the box of back up electronics and purchasing someting else. I can't comment on the stereo use because I haven't set this up yet with my phone.Score (1-10) 4Jabra BT8010 Stereo/Mono Bluetooth Headset
