Superlux HD-668 B MKII

Very comfortable fit for my head and feel better than all superlux cans I used before. The push-adjustable headband works great and even the pads still feel very good after prolonged use.
The standard noise from the headphone casing while moving, but surprisingly little from the cable itself.
Sound very neutral and can be eqd reasonably well for different uses. The highs, however, sounded pretty good to me out of the box, so there's a high possibility they could sound harsh for people with healthy hearing, as that's where I always have to adjust to my hearing profile normally.
The 3.5mm input jack is absolutely fantastic and feels superb, time will show about longevity. The cable and input have a small locking mechanism, so this should be kept in mind when cable replacement becomes an issue.
Overall great improvements in all respects and a clear recommendation as my new favourite superlux headphone out of all that I've tried.
