those headphones are total crap. good bass perhaps but at the expense of everything else. the quality of the bass itself isnt even good. its just boomy.
i owned a pair of xb headphones for 1 day before i returned them. so muddy it wasnt even funny.
you would do better to return them and buy something like the audiotechnica ath-m50s on ebay for $100-130. they provide decent bass but not at the expense of everything else.
you can use any headphones for gaming... but some are better than others in terms of quality.
