hd 25's are the one if you dj or produce, i had a pair once an left them at a gig.
but didn't the guy who started this thread say he wanted them for listening for 6/8 hours a day? i found the hd 25's very uncomfortable after a couple of hours due to the size of the ear cups, i also found they fell apart a bit after being used apx 5 hours a day after just a few months.
if you want them for listening all day + the odd bit of production then id get somthing the
beyerdynamic dt 250. just over a year ago you could pick them up for about 70 quid, by the time id saved up my cash they've doubled in price!!
still amazing quality production headphones, large comfortable ear cups for long sessions + a nice slimline design aesthetic so lightweight. ive also seen a couple of people, including jakes, use them to deejay.
thats were my money'd go + id urge you to consider
comfort before diving in for a pair of hd 25s (unless you deejay)
theres not really such a thing as "good headfones for dubstep", you just want a quality, flat sound. if youve got 100-200 bucks stick to brands like sennhieser , beyerdynamic , akg + sony an u shud be fine!
