Just got these a day ago.
TL;DR: They sound half as good as they look.
Included cable is awful (kinks too easily); carrying bag feels kinda pointless (these don’t fold flat so idk); earpads are easy to remove and annoying to put back on; moulded plastic strain relief for headband is questionable; headband is stiffer than I’d like.
Bass is flat, extends pretty well, not good for bassheads. Midrange is not good, sounds muffled and sometimes nasally. Low treble is lacking, the rest of the treble is meh.
Just get a 400i/4XX or a Sundara (more comfortable too) if you want a more modern look. At 300 (or 250) they’re not worth it for the sound when something like the 400i/4XX exist. They do look nice but that’s just not enough.
