This is yet another ear piece for my mom. (Not a clue what she does to them!) Anyway, she looks like iron man with this 1! It's really clear to hear her when she calls & all background noise seems to be vastly reduced. The battery life is good, but having the spare battery makes it so much better, especially as my mom can spend a lot of time talking!! It is a good product for a great price, is easy to pair, charge & use & seems to be a sturdy bit of kit!
