Cable management on (wired) In-Ears

I am looking for advice on how to manage the cable of my In-Ears. I need ones with cable because of lack of bluetooth, and I need them to be small because I usually have other stuff to carry around, so please don´t recommend wireless or Over-Ears.

I currently use a small zip lock bag to put them in after use, but even there, they get tangled up, unless I spend the same amount of time storing them as I do now untangling them.

So...has anyone got an idea on how to store them better, that is, faster and without getting a giant knot? Or are there small and easy-to-store In-Ears that I am unaware of?

PS just to explain my use case: I recently got a mini-keyboard that fits in my backpack which I use to play on my train and bus transit. It only has a 3.5mm jack. Sometimes I get carried away a bit while playing and then have to frantically pack everything in order to not miss my station.
