We used to have earbuds that don't need to be charged because they had a headphone jack, didn't get lost so easily because they had a cord attached to a headphone jack, never lost the bluetooth connection because they had a headphone jack, and they cost less because they had a headphone jack. https://bsky.app/profile/daisyfm.bsky.social/post/3l3mfjc6sn62k
How do I jam a set of folding over-ear headphones into the top pocket of a backpack without tangling the cord with all the other crap I have in there?
Take and fold lengthwise in half twice. Hold both ends and the give it 3to 5 twists so it now looks like a twizzler now ball it up and jam it somewhere as long as its some where tight. It won't tangle cause it already is. When you ready for them just pull them out they will untwist themselves generally.
It doesn't need to be tightly twisted just enough to hold it.
Small cases for them existed. They were small, but big enough to coil the cord in without damaging it. I've used some HTC earphones from an old smartphone. I don't remember the model, but it had flip keyboard. One of the first smartphones. Those earphones are still going strong. They gotta be 15 years old or so. Easy to clean too.
I was doing this for years.
