Hi guys I want to share my personal experience with this headphones, first of all this is overpriced headphone and do nothing in the name of noice cancelling, instead turning noice cancelling on it just enhance the sound quality a bit, overall product looks like made from cheap quality material, and the cord used in this looks very cheap and thin, it can be easily broken if not handled properly. I bought this headphones from Roorkee and in one month one the sound from left speaker starting to lag and some days later it loses all the sound, thankfully it is in the warranty period and got exchanged in 15 days.
