Sure the sound is ok, bass is nice but their better suited to dance music. Rock sounds awful and turn your iPod up more than 75% volume and it will start to distort
The biggest problem I have with these is the cable, the length is just so wrong. It comes in two parts, the smaller cable is so short it won't reach down to a coat or jeans pocket and with the extension you end with tons of extra wire just getting stuck and wrapping around things - it's crazy. Also the wire is soooo thin it tangles at every opportunity.
Probably won't last a month - commuters beware.
