I got these when my trusted DT-770s finally refused to work (after 10+ or even 15+ years 🙂), and they’re working great. I didn’t expect it, but sound-wise they’re quite an improvement over the DT-770.
However, they are a little less comfortable — though that might just be because, after all those years, the DT-770s had perfectly adapted to my head 😉
Highly recommended.
