> I feel your pain, and I just buy bunch of them so I always have some. Sadly many don't support all the features of a headphone port, meaning TRRS with control, allowing you to use an external microphone and play/pause/skip buttons as well. I'm using some tech that actually makes use of that, specifically as timecode reader for AV stuff. I need my phone to be a modern version of star trek's tricorder, not a piece of jewelry.
