I'm using this product past 5 months and its b'ful and awesome sound quality. I didn't found any issue with this product. Easy to configure and connect. It works with my Sony Erricson W580i Walkman phone as well as my laptop. Sound quality and beats are very good. Distortion only if u move your head 90% on left, but ignorable. Its not bulky and fit easily. Its in build mic is good. While playing a music if call comes u can atend it with this headset. It has its own volume adjustment. Overall, a good peace which makes me fully satisfied. I got what i was looking for. no wire hassle now.
