Headphones were bought 3 years ago, the first revision. They had very bad plastic mounts (it seems that this was fixed in the new revision). White noise infuriated (you can hear if the headphones do not reproduce sound), for the "audiophile" segment this is of course nonsense)). I didn’t find how to fix it, on the forums this is not considered a minus)). I listened mainly through usb, connected to ps through 3.5 jack. When the fasteners crumbled (and on both cups), I tried to solder it all with hot glue, it helped for a while, but 1 inaccurate movement and the ear folded in half :) PS. treated with enough care, but it was not enough.
