re-using parts from an old set of headphones (the drivers and cushions) seemed a good place to start in designing and building a full size set of cans.
Its been a while so Iv got to find some of the other parts (in the latest versions)
Note the headband (two are needed) is quite soft:- more infill better
Will upload next few days.
BTW the old headphones were Panasonic, I will have to remember the model. Also thinking of making some in all black as the first set were made with whichever filament was on the printer at the time. Chow
