Sound quality is excellent, and the fit is fairly comfortable for this type of headset. However, it takes 3 or 4 attempts before it connects to my phone's music player (Samsung A707 SYNC). I'm not sure if its the headset or the phone, but it can be frustrating. It connects on the first try, however, with the same phone when making voice calls. Also, while it can work fine at some distance, it cuts out frequently if I have the phone in my pocket. Lastly, the speed of the music I'm listening to will slow down or speed up occasionally , but I believe that is a function of Bluetooth technology. All in all, not a bad deal for the price I paid.
