I like the "in the ear" approach. It's extremely comfortable. You have several options as far as finding a comfortable fit. It comes with a portable charger, which is a prelude to things to come.I could hear any caller without problems but in noisy environments they couldn't hear me. In a quite environment it worked very well. The battery is terrible. Their listing is "up to 3 hours". There's no way you can get that much talk time out of this. I heard allot of static. I couldn't wear my phone in the holster because of that.I'm a frequent business traveler and it doesn't work well for my needs. However, it does have some positive traits. The main two problems are extraneous noise problem and poor battery life. So if you're not in a loud area or heavy user it's a great headset.
