Sound,These are really bad, they can NOT handle any decent BASS levels without extreme distortion. I tried them in the studio but they bleed too much, so I took them to work and it was bad, everyone around me was able to hear the music I was playing.Design-The structure of the headphones is very poor. The ear-cup is held by a small hinge right in the center of the cup, behind the speaker. These hinges are very small and weak to handle any bending and twisting due to normal use; so the earcups snap out constantly, and they are held by the wire connecting to the other ear cup, which happens to be very thin.Construction & MaterialsThey feel like a cheap 80's imitation Chinese toy. They are very light, the padding is inflated plastic... cheap... beware, do not pay more than 10 bucks for these.
