I can only speak about the old K140 which I recently sold to a friend. For the 30 bucks that they cost, these are very good. Although they lack clarity, extension, detail, soundstage, and all the other hi-fi seasonings, they absolutely nail tonality excluding some treble roll-off. The bass is pretty respectable on them and very well integrated with the midrange. The treble is pretty rolled-off on these, but still somewhat well integrated with the mids. The midrange is just great. It has a weighty, grounded vocal presence that sounds very "right" to me.
