⁕ As you see the back cover is modularized design. I might do some different shapes of back covers and update here.
⁕⁕ Sorry that I have difficulty on headband design. It's not easy to design an adjustable
headband with PLA material. I will keep thinking about it and maybe upload a better version soon.
⁕⁕⁕ DO NOT use fenestrated earpads on these cans. They will eat the bass and mids badly and give you painfully harsh sounding.
Add adjustable headband. File name: HD_V1.2_ADJ_BAND.STL1, HD_V1.2_ADJ_ARM.STL2, HD_V1.2_ADJ_STOPPER.STL*2
