Pick my headphones

Go for the Technica or Sennheiser.

Get the M50

These but if you must go with one from your list then I'd go with sennheiser

i always pick up $20 ones from walmart cuz that is all i can afford. Current ones have lasted 3 1/2 years.

DEFENATLLY AKG K 272 HD !

I have ever had better headphones then this one

Here's a very, very good analysis: http://audio.tutsplus.com/articles/general/headphones-roundup-audiotuts-readers-favorites/

Done by semi-pros.

AKG K240 MKII or Audio-Technica ATH M50 is what I would go for, all great headphones/brands though...

I have had the creative fatality USB headset, worked great, lasted me 3? years. Rocking Logitech G35s. I love them, they were on sale when I got them. They currently are on sale again, $95USD, not sure what that translates to your currency though :X Guess it's 77 euros.

I use Arctic Sound P531 and they sound great, specially for their price.

from those, I think I'd say go with the ATs
I'm no expert, but here's my reasoning:
A quick perusal of head-fi.org forum threads (my go-to spot for headphone research) seems to indicate too many niggling issues with the wirelessness of the Senns.

For the K271: fuck coiled cables. Personal preference -- I just hate those.
[edit] seems I didn't look at the Amazon pic long enough -- apparently it comes with both types! [/edit]

For the K240, I'm not sure if you know what open/closed/semi-open mean. Closed-back headphones try to keep all the noise from escaping. For people around you, they're the most "polite" headphones. Open headphones don't do that. As a result, open headphones also often have a better EQ balance, and are more likely to annoy everyone around you who doesn't want to hear what you're listening to. Semi-open is somewhere in between. They're closed-ish, but plenty of sound leaks out so you can't really call them closed.

For the 272s, I've already disqualified two AKGs, why not DQ another and make my/your decision easier?! :D :P

Also, I own some Audio Technicas and enjoy them. If I bought another pair, I'd go with a different brand simply for the variety, not because of anything I don't like about my ATs. (Mine are ATH-A900LTDs, if you're curious.) Mine have extra padding and rigidness and are fairly comfortable for long periods of time (hours upon hours), but are also a bit bulky. I can't speak for the comfort of the M50s you list, but they are probably much more portable (looks like they fold up nice), which is also better for DJ-style only-listening-with-one-ear (which can be more helpful than you might think, at least when doing music things even if not DJ music things).

I also have two pairs of AKG mics that I like well enough for their relatively low cost, so I have no hate for AKG if you go that route.
If they weren't wireless, I might go with the Senns -- they have a generally good rep too.

THANK YOU FOR NOT LISTING BEATS!!! :)

[edit] Also, if you can check if whichever has a 1/4"-1/8" screw-on adapter (like so) -- that was a nice little feature to have on my AT's jack. [/edit]

Senheiser, thats all I have to say :)

The ATH-M50s!

Pick your headphones? Any? These

You should really go for the Sennheiser Pc 360 it's the best gaming headset.

You should go with ATH M50 or AKG K272. AKG K272 are far superior to M50 but they're really hard to drive, unless you already own a good amplifier you should probably go with M50.

Sony XB700, half price, same good :P

I would buy the Akg 271 MK II. They have a great cost/performance ratio , a separate cable and different earpolster.
