Finally, a Bluetooth that does what it says! Lasts all day, and longer if I don't turn it up all the way. The sound quality is amazing! I've tried many others, but I can actually hear this one really well. The sound has good bass and treble when listening to music, movies sound great as well. The call quality is superior. I was so amazed with this earbud that I will be buying another, just in case I break or lose this one. It is very comfortable in the east as well. I have small ears so the larger buds tend to hurt after a while. This one did not. I wore it for an entire 5 hour shift and it never hurt. Pairing took about 5 seconds. Super simple and quick. I let me friend try it on his phone (he is not technical in any way shape or form and has limited vision.) He got it paired the first try in the same amount of time as I did. I am very happy with this purchase
