Comfort and quality is great, though not having removable cable is bad for any headphone over 60€
Sound is not great, piercing high end even after 40+ hour burn-in time,
the frequency response is by no means flat, the low mids are very boxy, yet hollow, there's little sub information and the bass simply doesn't exist from 60 to 120Hz.
These are perfect for spotting high frequency clicks and pops, but they are so fatiguing at everything else that I could never mix or listen to music on them.
I prefer my AKGs and even Superlux headphones
