lil update:
I pretty much figured they were going to be more for dj/producers that are on the go a lot and need something good, and he kind of talks about it in the vid below.
the specs on them were pointing toward more of a hifi type of dj headphones.
They wanted to improve on the hd25s, not realizing that what they are famous for is not how comfy they are, but just how light and flexible they are. Headband on these guys is HUGE.
Hd25s are here to stay.
They still don’t look as professional as the HD-25’s, and I doubt they’re as good, although Sennheiser do have a high standard. But the HD-25’s do everything a DJ headphone needs to do apart from fold, why fix what isn’t broken?
