Need advice on Headphones and USB amp/soundcard

[a66as]

Hey guys, after doing some research i have concluded that i would be better of getting a pair of headphones/usb sound card than a headset for my purposes (gaming/music/movies etc). I want something with bass (fun sounds) as well as been able to hear crisp gunshot sounds in bf1 for example.

I was looking at the Sennheiser GSX 1000/1200, what are the differences between these and do they really make a difference from the cheaper offerings?

I went with a GSX 1000 and a Sennheiser game one because i got a 20% discount on them brand new. What are you opinions on them? i only play games and watch movies and the game one are meant to be similar to the HD 598 which isn't a bad headphone.

I meant game One not game zero, which are open design headphones. i also purchased a fidelio x2 of amazon to compare the two and will be keeping the one i like the most.
