Had these, but sold them when I got a pair of KSC50, which gave me a much more enjoyable and clear sound. The KSC75 had very little bass impact, cut-off early in the treble, poor detailing in the sound. Both the KSC75 and KSC50 have a problem with comfort over a longer time of use, the clips make my ears tingle and hurt! But for a short listening session when I want some "open" sound on a vacation, the KSC50 is usable. They do provide the bass and detail that the KSC75 does not.

I tried these from a shop, they did look very nice when first spotted. I wanted some nice speakers to use with my laptop, and that could be transported if I was going away for some time. The sound was also important, of course! But these failed miserably! The sound was flat, uninspired, lacking of details and punch! Even trying a better DAC, and equalization, the sound from these could not be made to be what I wanted.   I got the B&W MM 1, and is happy with them!
