Negative Positive
Title: Compact but hardly usable
Review: Goods:Small, lang-lasting battery, very easy to put on, comfortable to wear, easy to install... in other words it could've been a great device if not all these...Bads:I could hear people at the other and of the line well only provided it was quite around. Standing on a busy and therefore noisy street made me upset because I could only guess what my friend just said. So, if you plan to use it in the car and it's sound proof then it's a great thing, otherwise... disappointing
