I’ve been using the Anker Soundcore Space A40 $90 they work well and are comfortable. Link

There’s a podcast (Sad Oligarch) that outlines a lot of these “mysterious” deaths in Russia.

I recently had an issue that caused similar issues. Ended up being a bad wheel on the Z axis. Wheel was damaged and the carriage would move up and down as the Z axis traversed causing that stripped pattern.

Good luck!
