I have this headphones before. I purchased it from online because of the trust in Sony. But I utterly disappointed with this product. This product is not so good. Sound quality is good. But the volume is very low. The bass output is also the same. Only the design is good. The product have a good quality in making. I purchased it for Rs.850 including delivery charge. The price is very high according to the output providing. I really disappointed with Sony. I have Sony headsets which provides a great quality sound and bass, that is why I decided to purchase this headphone. At this price I get good headphones which provide a good output than this. I purchased JBL headphone after this which provide a massive bass and sound quality at this price segment. I have to say to the people that you can buy a better headphones for this price range.
