Battery longevity I have no idea as of 9/31/19. The pain is so bad on the balls of my feet, arches, and heels I could cry. The other recommendation I have is when lifting or dismounting the bike, lift by the cross bar (or ladies adaptor bar attachment) because I also got my finger pinched in the handlebar when the front wheel moved. Very comfortable, well made and they look good! Can?t go wrong here. They do seem like they would be very comfortable if they werent so narrow. I?ve now bought these twice for my three year old. I?ve been very picky in my search for, what id consider the perfect AirPod Pro case. I get to ride my Mountain bike, just ain?t going anywhere when I do it. A young man has the job to convince her to do so.
