Need some advice from gamers !

First thank you for your answer. Siberia V2 has very good comments but I don't have a soundcard. For now I will use it with laptop so that is why I am looking for some USB headphones but it is also important for it to be a modular design. So, I can use it on other devices too. I think I am going to remove the Plantronics and Creative from my list.(Plantronics have Win8/8.1 driver problems and both are not modular.) So, my new list is like that I think:

1)Sharkoon X-Tatic S7
2)Steelseries Siberia V2

Sharkoon is not so popular but the users are all satisfied from what I heard, it also has Dolby Pro Logic IIx trademark from Dolby's website. It is also coming with an amp and has modular design.

Now, I have two options:

1)Sharkoon with its own amp included. ~115$
2)Siberia v2 + Creative Soundblaster external soundcard ~ 160$ total(Which is way too much for my budget : /)

Isn't there someone who is using/used Sharkoon?
