Thank you so much for your reply. I think your answer is very valid, probably a waste of money I guess. I was thinking about getting some studio headphones and then get an external microphone. I've went to the PC Store / Audio Store and tried some headsets and I'm quite disappointed in the gaming headsets. They don't feel too god and the Razer Carcharias that I actually own, well... they suck nonetheless imo, does not fit me too well because they give me a rash, picks up a lot of dust and it leaks so much! Great microphone though.
I guess I'll get a Studio Headphone and External Microphone, thank you for helping me choosing my option.
BTW I live in a Japanese Mansion but I think having a kick ass setup would make the neighbors mad. I think they will hear 🙂 Also it's very hot so I have my windows open and I'm 100% sure they're going to call the police by hearing the sounds coming out of my games haha !! ^^
