I needed a headphone clip to attach the wire to my shirt so it didn't bounce around. I've got them on my JLab headphones, but it's lacking on my second set of Bluetooth headphones. I'm currently lacking access to my printer and my measuring tools, so the measurements are obviously not accurate, and untested. But generally speaking, so long as you scale both pieces, they should work correctly. If you test it, let me know how it works!
