Really? I like the MA900 a lot but agree it was grainy, it's been a good 3 years since I've heard one though. The MA900 sounded pretty unique to me it's design made it have a weird soundstage that I liked, it's resolution wasn't really that great, a tier below the AKG K7 variants but I got mine pretty cheap.
those Mysphere 3.1 look interesting, Headphones like that I'd usually use for gaming, I have my HD800 that I use for my PS4 so prob wouldn't look to add those but I'd love to hear them, anything unusual and odd always gets my attention.
I've said it before but I'd love for Skylar to make an open headphone, IMHO the Night Owl was a huge waste of time, it has the same issues as NH but some of them are even further exaggerated. NH was pretty closed, has a closed back sound and a small amount of leak so it was pretty pointless in my opinion to go for the Owl.
The NO also doesn't really improve over the mid range headphones like the THX00, Ether C and Flow an it's just another one in the mix. An open headphone with bio-cellulose drivers(Never before done? I wonder if they are not meant for open housing?) I think closed back headphones are as good as they are going to get and the price is the only thing increasing.
Like an Audeze shape or something completely new but liquid wood, have different styles, get rid of the dorky, halo above the suspension strap and keep the protein leather strap as the only part of the top. Make thicker ear pads too. Distortion will be higher but you also gain so much more with an open design.
