The "charging case" is more a custom built power bank that fits tightly into the original case (or an aftermarket case) than an actual "charging case".
The build is based around a 3D-printed enclosure, an off-the-shelf power bank PCB with micro USB in and USB out, an 800mAh 16340 (CR123A) li ion cell (I used a protected cell from EEPOWER because you know, reasons) and a cheap CR123A battery holder.
You cannot charge the case while it is closed and you cannot pass-thru the power to the headphones while charging the power bank. If anyone is interested, I can upload the mechanical files (Fusion 360) and the BOM to github but it will take me a couple of days. The design is not 100% finished and I am currently testing. Once I am done, I am going to glue it in place.
I have ordered an angled USB cable because I was unable to make it fit nicely with the original cable as you can see.
It should work for
Cheers, André

as they are all the same form-factor.Cheers, André

Well, why am I even asking 😉 I finally found the time to upload everything in case someone wants to build one:
