If you enjoy crappy mid's/high's, but love low's.. the Beats 3 Studio is fine.
If you want to hear someone sneaking up on you gaming, you're going to want to switch to a gaming headset. Astro, HyperX, Logitech & Turtle Beach all make great gaming headset for $99 or less that are great.
Then again, you got the Beats for free. You may as well use those.
