If it were just a regular one I'd try, but doing a large wall mountable one...meh.

No man...you got's ta have the iron fist of awesomeness...& exceptionally happy bright thinkin. Dude throw a couple ideas at me and I'll incorporate it mvitkun

What area do you need help in exactly, kingsley? I've been thinking of partnering up, don't want to do this myself if at all.

Sure...erm..not a pro at 3D modelling but I could pretty much sketch a 3D model anyhow. Why not MrYuriy :D

Even though they want a wall mounted headphone arm, I'm still gonna design a stand #Becausewewantto

something like this?

or possibly alternating top->bottom->top-> extrusions for each headphone so that there aren't issues with larger headphones.

Not bad. Like the main portion of the mount but the headphones don't look like they'll mount as easily as expected. Maybe Pinch tags which are magnetic to connect to the pieces of aluminium that have been extruded out/cut out.?

What about a peg board design?

You could either have a bunch of smaller arms or you could have one large rail that you put all the headphones on

Sure :) basic but yet functional. Sounds more DIY but yeah.

I'm not suggesting they sell the pegboard, I'm suggesting they sell the headphone arms/rails.

So that you could buy either the single headphone arm that goes onto the peg board or something like a telescopic rail in the shape of a headphone holder that can extend outwards to hold however many pairs of headphones you need, to a point.
