this is an excellent product for music lovers the quality of sound and bass is amazing the deal that i got from flipkart was also brilliant and delivery timelines are pretty smooth additional 6th star for the design of this amazing headphone talking about the battery back up its very decent if you have a use of around 3 hours a day then the bettery can last for 56 days compatibility and comfort though the cushons are good and fit well on your ears but this might trouble you if
