My budget is $150, but i can rise up to 200, no more. I'll using these headphones on my sony ericsson w995,
i also have a sony walkman a45 ( brand new sealed, which i'll open when my current player dies). I listen a little of all genres. By the way, i am planing to use these headphones indoors only. Thank you very much in advance.

The Sony MDR-7506 is more of a studio monitor (kind of boring) headphone.
The Audio Technica ATH-M50X is a bassy headphones, it's decently ok, but not really outstanding audio quality.
Check out the Audio Technica ATH-ESW9 or ATH-WS99 (buy used off eBay).
