OpenFit

I use bone conduction headphones. They are great. The best thing is cats approaching from behind don’t scare the crap out of you when they suddenly appear out of the corner of your eye. I’ve tried AirPods with passthru and shockz bone conduction headphones. The battery lasts longer on the shokz.

Shokz (or other.bone induction) are literally the answer to this question I also sometimes use open ear buds (I tried a few. I've some soundcores that do the job) to swap them for when they are charging on very long rides as well - my shockz are only good for 8-9 hours or so of solid play time.
