Neat idea to gather criticisms!
I can't say I dislike them, but I do have some criticisms:
- The headband plastic is prone to cracking.
- They can be a little bit clampy out of the box.
- They have a tendency to make everything sound "good" (what I mean is, they smooth over things a bit much imho).
They're good headphones overall, but they're not perfect (no pair is); if I had to pick a headphone over them, with no price consideration, the ESP/950 would be it, if I had to pick something in their price range, then I would look at Grado or the Sony open-back cans (like SA5000 or F1).
I've had mine for about 15 years. Not a single crack.
As I like these cans won't say anything else about it :)
