I bought the headphone 2 months before. after using it for 2 months I can tell one thing honestly that this is the best headphone at this price but though it contains a little problem. the 3.5 mm pin sometimes get a problem in which I have to push it a little then it sounds well. The feature of adjustment according to the size of head is just marvelous.the quality of sound is top class but still a little irritating sound is heard. this is user friendly as this has an adjustable mode in it.the cost of this headphone is less in compared to the other headsets but it should be a little more less. as I have bought this product from amazon at rs 999/-. but Sony should reduce the price to at least rs 600/-. but still the product is good.
