yeah if those are your 4, I'd def stick with astro.
is one of the better wireless models out there now, but if your goal is sound quality, you would be wise to look at audio-technica like edogawa recommends.
the 700s are awesome if you have a big head / large ears. hard to find headsets that cater to that
also look at the ATH-M50. one of my favorites in that price range. stereo but amazing nonethelesshttp://www.headset-ratings.com/audio-technica-ath-m50-professional-studio-headphones/
happy gaming man!
