Well I bought it in October 2014, so I have been using them on daily basis . the headphones are pretty good in terms of build quality and design . The cushioning is also great but the bad thing about them(well all such sort of headphones) is that they are on ear headphones. so if you use it for long periods of time then your ears will hurt . These headphones are a bit tight and I have to take them off every 15-20 mins .
As for the sound quality it is really excellent . The sound is crystal clear and if you are a person who loves listening to soft music then these will suit you the best . For all the bass lovers out there it lacks that part . Bass isnt bad but its not up to the levels of the competition .
