Headphones for PC

So I was thinking about upgrading from my Sennheiser PX100 (I think) and getting some new headphones for PC use. Here's some I found (I want them to be comfortable for hours of wearing).

or http://www.amazon.com/Audio-Technica-ATHM30-ATH-M30-Professional-Headphones/dp/B00007E7C8/ref=sr_1_cc_1?s=musical-instruments&ie=UTF8&qid=1323722992&sr=1-1-catcorr

or http://www.amazon.com/Sennheiser-HD448-Closed-Circumaural-Headphone/dp/B002DGTGO0/ref=sr_1_cc_1?s=musical-instruments&ie=UTF8&qid=1323723052&sr=1-1-catcorr

These ones are on sale so I don't want them to be too expensive. (sorry gamespot wont let me link it..)

• All the headphones you listed are well-regarded, for the most part
• Did you read the sticky? There are some very good suggestions in a variety of price ranges, there.
• You can add links by using [ url= http://www.anysite.com ] linked text [ / url] without the spaces

Good luck,
