Finally I've found the perfect fit for me, Its small and comfortable.

Very nice comfortable fit and amazing clarity

I like the long battery life,as well as the comfortable fit

It's light, and took a bit to get the right fit, but after, no issues.

the little door/cover over the microUSB port gets in the way, the device is clunky and poorly balanced, and worst-of-all the ear hook is a poor fit to the device so that the thing drops vertically and doesn’t stay pointed at one’s mouth (and it’s a non-standard size, so it is hard to find a replacement)

Fantastic!I am so happy about finally finding an earpiece that fits in my ear so well
