I have noticed retailers are selling these things that keep your headphones from getting tangled. They are especially being pushed on gift guides this year as stocking stuffers.
That’s cool and all, but we don’t need to be sold another product.
Open your kitchen drawer.
Use what you have.
I have a TON of twist ties laying around and I use them for everything. Both sets of headphones are controlled by them and I use a stretched out hair tie to corral another charger cord.
The point here is, look around your house and see what you can use before adding one of those things to your shopping cart.
