Sonny you seem like a headset guru, what's your opinion of the Razer Kraken 7.1?
omg don't mention them again. they are a gimmick, i could show you £15 headphones better than them seriously. I sold a pair of £30 headphones in the mm once for £20 and the guy in there was embarrassed to say they sounded better than his £200+ beats. all i have done is researched plenty on head fi it's the best resource for headphones and headsets. sound city on here though as just a good base to learn from.
look in sound city Joe there's people in there that will tell you everything you want to know about a headset. just make your own thread plenty on here do.
imo though everyone should have bought HD598's yesterday from amazon for £75 (black friday deal).
your talking having to spend £150+ to get something slightly better than them for competitive gaming and it's what I use 95% of the time (well i use HD558's that can be modded into 598's by removing some foam). seriously anyone who was looking at a new headset should have bought them yesterday absolutely ridiculous price.
this is a good thread for ideas

do you want a competitive headset (for footsteps) or for immersion (loud explosions, etc)?
competitive:
hd598, k702 and k712 are the top 3 worth mentioning they all require a seperate mic like the antlion mod mic or a clip on mic from china for less than £1.
ATH-AG1
is what you would call a headset on par with the above headphones it's £240 though so as you can see buying headphones and a seperate mic is much cheaper than an all in one.
if you want all rounders that are good for immersive gaming:
hyper x cloud v2, fidelio x1 or x2 or DT770's
the most imo anyone ever needs to spend is £50-£200 there are some crazy people who can spend £1000 on headphones.
I own HD700's, Q701's and have owned HE-400's (now sold).
They are only marginally better for gaming imo than £150 headphones. So when I say £50-£200, the top end of that budget will get you a set you never need to upgrade from ever again in your life.
for people with a very tight budget koss porta pro's are £28 (plenty of mods for them on head fi which turn them into monsters). Koss KSC75 are £15 and use the same drivers but not as comfortable.
i would say those £15 clip on's would be better than the razer headset you mentioned.
DT770's also were on sale on amazon yesterday.
I believe DT880's are on sale today on amazon, worth checking them out (lightning deals).
edit: think you have missed that one also unlucky
