I recently switched from wireless to wired headphones (Samson SR-850, probably the best for the very reasonable price) and my chair’s wheels instantly started eating its cable. Right now I’m using a small plastic hook that came with a face mask to keep it off the floor, but I’d like to hear other solutions.
My pc is on top of the desk and the ports are on top. The cable just hangs down and it is sufficiently long to allow mobility even a bit further away. It is also short enough that it cannot touch the floor.
