For the price, I would question whether you can get better sounding headphones. I have owned the Klipsch S2s, and various Sony and Sennheiser headphones, and none of them have been a patch on these. The soundstage is broad, bass is heavy but not muddied, and mid and top-end don't feel overpowered or tinny. For sheer sound quality, I'm not sure that these can be beaten at this price.
My only minor qualms are with the build quality. While not flimsy, per se, the materials used don't feel as high quality as you get with some bigger brands at similar prices. The cable seems to lack flexibility, and feels plasticky, while the ear tips also feel low quality. I suppose that the cost for these has gone into producing high quality sound though, in which case I can't really complain.
