I've had mine for nearly 5 years now, and they continue to deliver the goods reliably and without any fuss. The first pair I had gave up the ghost after about a month, but Sony replaced them no problem and they haven't looked back since.
The sound's good - not too refined if you're really particular, but they're bombproof, comfortable and an all round good product.
I'd buy them again, except I want some Grado's now..

these are really good value for money, i've had mine for a while and never had any problems with them. the swivel cups are really handy, sound quality is pretty good for the price and they look pretty good too.
