The good news is that there’s function to the form as well. The Nitinol headband is very lightweight and that teardrop shape just hugs the contours of your jaw in a way that keeps the headphones from shifting around.
Sonically, they lean more towards analytical and I understand why some owners think of it as a closed-back HD600, but with a little planar flavor. Feed it a good source/signal chain and it’ll keep your ears super-happy.
If it helps, you can find my writeup/impressions on the first listening session with them here. After a couple weeks of use at work, I started to appreciate them more on bass-heavy stuff. It’s still definitively planar bass, but putting in the tuning pads does help a bit with taming down the treble and allowing the bass to loosen up.
