The IM70 has a ton of bass. In certain situations, it sounds better than my over $1,000 modded beyerdynamic T1 and $400 toxic cable. I'm now debating selling it and getting a IM03 and a cheaper headphone. AT has a winner with these IEMs.
if u are looking for subbbbASSSSSS.... u will have to wait for your can to settle...
50 to 200 hours depending on who SAYS it...pataburd or his cronies.
then.....u open that HOLE,
and fill it with subBASSS ingredients...stir the pot..
and taste the brew..feel the reverbs,
then u can quit...in bliss.
....I don't even know what to say, no gif can express it.
