What's the little plastic clip on the headset good for?
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?!?
It's good for avoiding tangles when you're not using your earbuds, or when you are using them, from preventing you from tearing your earbuds. (When you're jogging or whatever.) That extra clip is the first thing to give when you pull them apart. If that wasn't there, the next thing to pull would be the splitter. Then you'd have half a pair of earbuds.
I actually find it very useful to clip around the buttons on my dress shirt. Depending on the amount of slack I want, I can pin it around different buttons.
It creates enough slack in the lines/wires that go to the ears:
- reduction in cord noise carrying up into ear-buds
- the mic in the right wire stays away from your body (better pickup and less noise
- if the earbuds fall out of your ear, they don’t drop all the way to the floor
It works perfectly (see yellow arrow in picture):
The usages you described are the correct ones. The Headphones ones are really lame, but it does its job on the Macbook’s power bricks. I made a pic for you:
I can’t find my iPhone earbuds, but the idea “is more or less the same”.
