I had the SE-A1000 for a while. I really enjoyed the sound. I didn't like the comfort. The elastic that runs through the headband is too loose. I would have had to modify the band to have more resistance. But as far as sound quality, they were very nice and clear with a pretty wide soundstage, especially considering the price. I picked them up for $30 when Best Buy was clearing them out of the Magnolia stores, but ended up returning them simply because they didn't sit on my head properly (same issue I have with AT wings, it slid around) and it didn't achieve a good seal so the sound was inconsistent for me.
The comfort issues vary from person to person, and I think it makes a nice gaming headphone if you can get it to fit properly. I'd say pick it up and try it out. Also, the 10' cord is great in some cases, annoying in others.
