I'm looking to upgrade my earphones (sen cx300) and i.ve seen these on ebay Ultimate Ears Super.Fi 4 for £50 including delivery from usa
i.ve read good things about ue on this site but not these ones because there new i think
the superfi 5 are just too costly at nearly £100 the price for these seems quite good! the music i like to listen to rock punk that sort of thing, does anybody have any viewpoints on these earphones or ue in general?

thanks
