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.
I wish that worked for me. The armrest of my chair catches onto every bit of cable it finds slightly hanging off the table. Granted, that’s only an issue because the armrest is T-shaped rather than O-shaped.
