I LOVE this blue tooth. The boom mic that swings up out of the way, also turns it off and on. No more holding the button down just the right way for just the right length of time to turn it on! The ear piece also folds down which makes it easy to get on in the "mid" position. Very comfortable. Headset is light and I have actually forgotten I have it on. Fits well with my glasses ear piece also. Reversible for either ear. It will recognize the phone up to 30 ft away...I tried it! Crystal clear sound on both ends. Even when driving! Battery power (length of charge) is awesome. I've had it on for 2 days straight and it still had a full charge. Charges up fast also with the included charger. I've had other bluetooth devices and this is my absolute favorite. Price is right also.
