50mmdrivers...slurps..very very light weight..headband is some aluminium or flexsteel strip?
shallow velorpads...very very light clamp on the head, very very poor isolation...
very clean thin treble, lean mids...
"planar" like bass, the drivers trying to latch on to something to generate the bassheft
but to no avail..lol.
But i suspect,
this would generate some clean magic with classical pieces when put on a tube amp...
