I tried different sound mods but none worked well for me so i made a 360° Rotating Base for this one Quest 3 Koss Headphone Mount (with Elite Strap) by AlFlo3D - MakerWorld.
The Base replaces a cover one the S3 Pro.
I added my F3D File - beware i never use Fusion 360 or do 3D Modelling and building this costed me a huge amount of time but it somehow worked. But the file is a pure mess haha.
