On my iPhone headset (the one that came with the device, as well as the in-ear buds) there's a little piece of plastic that slides on the cable to one earbud, and can clip onto the other cable.
- It's not large enough to accommodate the headset cable below the split, so it can't be used to somehow hold the cable in place when it's curled up.
- It's not tight enough to stay in place if I slide it nearer the earbud, so it can't be used to essentially move the point where the cable splits closer to the earbuds.
- It's not tight enough to really hold on to the other earbud cable. It takes nearly no effort at all to pull the cables apart.
What in the world is it good for?!?
