I've had this pair of headphones for years, which is a great testimony to their longevity. Most pairs of headphones last me a year or two, but I've had these at least 5 and they're in great shape. I originally got this on recommendation by a friend of mine, saying that I should go for these over the more popular 7506 headphones that Sony offers. I compared them both at the store, and definitely agreed. You get a better depth of sound and realism in these phones than you do with the 7506's. The frequency response is similar if not exactly the same, but I think the difference is in the response to dynamics and transients. The quick hits seem more crisp in these.

The noise rejection is fair in these headphones. They do cover your ear completely, but they are not very tight on your head. That means they're more comfortable to wear which is also important, but that more of the outside noise is going to get in, and vice versa. So you might want to keep another pair around for when you're recording close up to a vocal mic, because you will probably get a little spill into the mic from these headphones.

Barring that complaint, they are otherwise a great pair and the price for them is fair. You definitely pay for Sony quality, but if you care about sound fidelity, it's worth the price you pay for their brand name. I'd get them again, listening to music sounds great in them and I like to use them while monitoring when I'm recording someone else. They also give you a snazzy velvet bag for safe keeping if you take them traveling, as well as a converter to go from 1/8" to 1/4". Nice bonuses!
