These headphones are really frustrating.   Poorly amped they sound acceptable, maybe with the treble a tad rolled off, but give them some power and you'll be clutching your head in pain at the sibilance and overly bright treble.   They look amazing, but the horrid curly cable lets them down (i've replaced mine with dual entry balanced XLR)   The pads could do with being a bit deeper, but it's easy enough to stuff them with tissue (tissue mod)   I'll probably experiment with dynamat to see if i can tighten up the bass some, and see if...
