they became more natural sounding with an adjust of the 10khz tone, sounded actually very good, quite good bass, better than most in bass thread
though the thing that made them not to liking, was their (world war 2) designed metal sheilding,
it took away some of the pleasure in listening to these headphones, if they would'nt have had that, it would have been a quite solid headphone
98-99% less radiation and 40% less hearing pressure on the perceived signal to the ear
they had a good vibe to them with dance-music
as someone mentioned for a less, price bought, they are really good, though the ear pads are too expensive,
if the metal shielding is not, of any disenjoyment
