Which ones should I get? Obviously the HD555s will be better, but is it worth the £20 price hike? I am certainly not an audiophile (currently own some 2.1 £30 Altec Lansing speakers, not sure what model), and would certainly like to save the money if there isn't a huge difference. The HD555s look better to me (don't like the 'stripy' look of the HD515s), but then again, looks don't make headphones. Comfortability, sound, and price do. Are they both ergonomically the same? ie. they will both feel the same around my head? These will be couple with an Audigy 2 Value soundcard btw, and used for a bit of everything - gaming, music, movies.
