thank's guys :) I think I will go with the Samson's or the Takstar's

that what I meant (headphones that sound good over style)

are they "real" sound or like skullcandy / beats?

I have no idea what that is but i want to play pop, rock and indie music  if it helps I have Skullcandy Hesh V1 at the moment which are nice and bassy but seem to lack mids and highs for me?

here are the headphones I am looking at, fell free to add your own options in :)   http://www.amazon.co.uk/Superlux-HD-662-Closed-Studio-Headphones/dp/B007IV7OBM...

So these headphones http://www.gear4music.com/Recording-and-Computers/Samson-SR950-Studio-Reference-Headphones/SUR?origin=product-ads&utm_source=google&utm_medium=cpc&utm_term=&utm_campaign=PLA+Samson&utm_content=z3BwRmUS|dm_pcrid_34028316559_plid__kword__match__And this sound card...

Which is the best for artists like the offspring, t.A.T.u, the killers etc.. FYI I use spotify in high quality mode (320Kbps)

So a sound card is the way to go? I was looking at the Asus DS but it didn't seem good for or windows 7? If I get the Asus DG / PCI (I have no pci-e x1 slots) what £50 do you recommend?

£100 max ish, so my "sound card" (VIA® VT1705) is good enough and its just the headphones?

I still don't get how half of this stuff works, don't get me wrong I am a computer engineer, but am new to audio stuff.   I have a ASRock N68-VS3 FX and am using onboard sound (48K / 24Bit) with skull candy hesh (V1) headphones.   I feel that the is something missing in the sound quality...
