With that said, try some Powerbeats Pros. They're the Beats version of Airpods, and frankly, I like them better. At $250, they're pricey as hell, but they sound better and they stay in better. With ear hooks and a collection of different sized buds, it eliminates trying to make a "one size fits most". If you don't have "Airpods ears", the Powerbeats are probably quicker to insert once you know the "trick" to getting them in. I always to have to fiddle with Airpods a bit to get them to sit right. Powerbeats: stick 'em in with that little twist of the wrist, sorted. And the Powerbeats have physical volume buttons, the lack of such being my one annoyance with Airpods.
I find that if I buy the old foam covers, they fit in my ear a little better and I can still close the case over them. It gets in the way of some of the sensor operation though.
The amazon buds look like they will fit more ears.
Depends on the ear (and maybe sweat levels)? Mine have never dropped that way.
I just bought airpods yesterday, and tried running with them for the first time today. I couldn't run more than 30 seconds without them falling out of my ear. (Kind of disappointing after spending $200)
I also have a Bose over the ear headphone. Too clunky for running.
These Amazon buds actually look like they could be better than Airpods for running. Looks like they have the "suction cup" type of design, which usually do a much better job staying in the ear when moving around.
