Then you should be buying monitor headphones such as Audio Technica ATH-M50s or IAIAIA TMA-1s. You'll hear the full range of sound, un-EQ'd, with extraordinary clarity and no emphasis on any piece of the sound with headphones like those, which is invaluable for someone working in a professional/studio environment.
ALSO please for the f***ing love of God don't buy Bose either. They're no less guilty than Beats of overpricing their subpar quality goods.

They're good quality, but not for their price range. They get matched/bested by $150 Audio Technica ATH-M50s, easily bested by ~$230 AKG 701s and Beyerdynamic DT 880s or 990s, and they're in the same price range as the much higher calibre Sennheiser HD650s. All of those, sans maybe the Senns, have very rugged build quality. I personally have a pair of DT 990s, and if looks matter to you, they're highly customizable as well as being super comfortable. Hell, I'd even say my old $100 HD555s had comparable sound to Beats Pros.
My favourite assault rifle in this game so far is the AN94, but the M14 from CoD4 was my favourite in the series.
