Look, you can debate the sound quality of headphones all you want, but I have gotten superb sound quality out of headphones time and time again. It is definitely worth the money, especially if they don't have a static tone that even many top-of-the-line SPEAKER systems have. Actually, that's much the same argument. I had terribad speakers for a couple years, then upgraded to a pair of, admittedly awful, Skullcandies as my "intro" to the over-ear headphone world. Even on such a bad product, I'd never go back. I got these XB500's three years ago for 80$, and it's only now that, since I have nothing else to upgrade, that I'm looking into a statistical improvement over these so I can carry them around with my laptop.
- I really, really like the recommended Beyer DT770's. Did some digging up on them, but I couldn't find the specific driver size on them (the XB500's is 40mm, if I remember right). If I understand correctly, the driver size has an effect on the bass play. !The fact that they don't have the ear cushion stitch on the inside of the ear cushion is a gigantic plus. I have no idea why these stupid headphone designers keep putting the stitch on the inside of the cushion (another reason why I enjoy these XB500's). Defeats the whole purpose if your ear doesn't match the headphone exactly! Another plus over these current is cable size, even if this current cable is probably the best I've actually had the honor of seeing (flat analog cable).
-I can afford the Sennheiser HD 598's. They look darn stylish...
