Project is realized with
- planar drivers made by Audeze for Kingston HyperX Orbit S
- wooden caps and steel headband from unknown chinese headphones called Hores P2
- 3D printed parts for cups and headband
- leather headband with elastic straps
- detachable cable with double jack 2.5mm
- ear pads extra thick designed for AKG K2 series (like K240)
- masking and labels cut from Oracal sticker veneer color mahony
Tuning was done by copying orginal design only:
a) volume behind the driver the same as orginal cups (salt has been used to fulfill empty original cup and then the amount of salt has been used for design 3D printed cup ring to get very similar volume behind the driver)
b) ventilatoin holes with the same total area as original cups (original cup has got 3 holes diam 2mm and new cup have 5 very small holes so they have been drilled out to 1.2mm each)
c) volume behind the driver has been fulfilled with original foam and couple layers of natural felt
Because drivers have got very small resistance, less than 8 ohms (and an impedance probably also is small), so additional resistors have been soldered for each driver to get resistance close to 32 ohms.
