I have been using this head phone since last seven days. I have not faced any problem yet with this product. It is a simple design along with 2 mtr length wire and small microphone, it also contains of volume rockers and the ear pieces are also comfortable because of well padding, the structure of this product is quite comfortable instead of its heavy weight. I got this product at Rs.400. In this price range this product is best. The sound quality of this product is awesome for this price range. The microphone is also good quality I have checked by recording voice clip and the sound quality is nice. Over all the product is good and value for money.
