Sennheiser PX 100 for Gaming?

[sreenisatish]

I am not sure if this is the right section to post this, but here goes..

I am planning to buy a headphone for gaming purposes.
As I game for long hours, these are my requirements:
Lightweight
SupraAural
Powerful (good bass is good for gaming right?)

I am not interested in microphones and stuff cause I dont multiplayer much.
I have heard reviews about the Sennheiser PX 100 and all the reviews gave perfect scores for it. But, most of the reviews concentrate on music performance. I am not sure if these perform well for gaming.

Does anybody own the PX 100? Is it good for gaming long hours?

Suggestions for other good gaming headphones are also welcome.

Budget: 3.5K

The Sennheiser PX100 has one negative thing that I would like to mention: They are not shielded properly...which means it will annoy the persons sitting next to you because its like loud noise for them
