I have had 2 pairs of these headphones now and am in a quandary as to whether I like them or not. The sound quality is excellent, absolutely no complaints there. The build quality on the other hand? The interchangeable coloured discs do indeed come off at the drop of a hat. They are presumably a very attractive gimmick (aesthetically speaking) but having to put a new set on every week becomes tiresome. The other issue, and this is not solely restricted to this set of headphones, is the weakness of the wiring around the headphone jack. The previous pair lasted approximately a year of simply being used whilst walking to and from work before the sound in the left ear went, the current pair has gone after about 6 months.
These are, in my humble view, impeccable sound wise but I wish they came without the spangly bits and with a 90 degree jack.
