Display Vision have a set of different OLED screens, can get them from Elfa Distrelec. In Euro the price for a 128x64 OLED screen is around 58€.

Isn't it possible to track who the maker is of the OLED display itself? I really don't think Steelseries make them themselfs, most likely a third party who builds them. If it's possible, I should give it a try myself. I actually have gone so far, so I bought extra batteries and an external charger so I can continue to use them. Was able to repair the "wheel" on the headset (wouldn't respond from time to time). When I get time (working too much right now), I'll try and see if I can do something about it. It still works, and is the greatest headphones I have ever had - can have Optical (PS4), USB (PC) and Bluetooth, and recieve signals from all 3 at the same time.. Oh, and I really need to make a guide how to remove and clean the wheel for volume on the headset!
