I both own the T1 an the Sennheiser IE 80, my two favorite headphones for at home and on the go. Both are very resolving and musical. So if you like the T1 chances are you like the IE80, required you get a good fit in ear, but the IE ships with plenty of different type/size ear tips.
Not to sound contrary, but what exactly occurred here? Was this an guinea pig run on some T1's...dare I say is that the new driver onboard a t1 (or is it a pure baffler* change). I think it'd be pretty nice to have a compiled list of the silent revisions (actual and perceived) that occurred through the T1's run history.
