What should I say. 3 years of use now and still playing lovely with several scotch stitches.I was listening to them on home stereo's on the max volume.They handle well without noticeable sound losses.The last year intensively with Nano 6th + Fiio E6. The bass is sweet.Can not imagine better bass from a portable headphones.Or at least not too better. Best for the price. A bit tight headphones though. I got used to it. The same as the studio Dre's on the sound but falls behind in materials and comfort.
