Not to be a dick, but: Head-Fi: Covering Headphones, Earphones and Portable Audio - Search Forums

use the search term: se530 w3*

choose the right sub-forum, and you're off.

I've owned the W3 and SE530, and I definitely prefer the SE530. The W3 sounded EQ'd to hell and back, while the SE530 w/ Comply tips sound very neutral in their presentation.
