I've gone through about 5 Bluetooth headphones and these have the best sound quality. The in-ear silicone piece is excellent very comfortable and doesn't slip out of my ear unless I really do some serious head banging. But the headset feels and looks cheap. I think it's a bad design. Very dated looking. Also the power slide button isn't real decisive. On many occasions the button was inadvertently moved to on when I didn't realize it and drained the battery.
