I would be very happy to see some solid breakdown on the technology used and (at least indirectly explains) how that correlates to pricing, because those of us who've been around this community long enough and have done the rounds with testing for various brands are honestly getting very tired of seeing a new lineup come out with prices that are generally plopped down somewhat arbitrarily at the various market levels.
We get it, we do. A few years ago everyone was rushing to hit the $300 segment broken by Beats. Now the new "entry hi end" is about $600, and the next is $1k, and then it's into rich kids playground in the 2k+ zone... and it's like manufacturers feel like they need something expensive to be taken seriously... But the market has matured now, and consumers aren't that stupid anymore are more educated.
Don't arbitrary price your headphone lineup to create a sense of which is "better". Don't shove something into the $1k bracket just because you can. In fact, tell us why you're better than that. Believe me, we'll listen.
Back to the original question... features/technology/accessories:
tech and features: if you're talking bluetooth or active noise cancelling, each is a different niche... are you making headphones for purists or for casuals? or that fuzzy market segment in between
accessories: swappable pads is the main one, a case is nice but depends on the headphone (very nice for foldable headphones, not so much for fixed frame but then a solid easily opened box is desirable), replaceable cable options with standard connectors will also be a draw
