The “Magneat” is a simple little wire management system that uses a magnet to clip to your shirt. By winding your headphones’ excess cable around its post, you’ll be less likely to catch them on things. Or that’s the pitch, anyway.
You can only buy them in Iceland at the moment, though, so you’ll have some time to consider how much you want them before you make the flight over. Oh wait — you can buy them online and have them shipped over.
Honestly, the wire shortening I get, but I’m not quite sure why you’d want to attach it to your clothing.

The best solution I’ve found is a short strip of double-sided Velcro, about 1 1/2 inches long. Wrap the cord around the middle of the Velcro strip until it’s about the right length, then wrap the Velcro around the cord and itself, hook side in. You end up with a small cylinder that weighs next to nothing. Mine has never come loose.
A roll of Velcro is generally great for cable management.
If you use earbuds, it doesn’t take much weight to pull them out of your ears. Depending on the ones you buy, sometimes the weight of the wire is enough to jostle them loose if you’re out running.
Being able to anchor the wire to your clothing is actually a good thing.
Twelve years ago I bought a tiny cable turtle, pretty much the same concept sans magnets, but a bit more colourful instead. Still got it/using it twelve years later, so it comes highly recommended.
but I’m not quite sure why you’d want to attach it to your clothing.
Because the excess cord catches on every damn machine at the gym. And gym clothes often have no pockets.
You’d have to attach it to something, or it’d just unwind, most likely.
