A:AnswerThe AirPod pro 3 are redesigned and do come with several ear pieces that fit your ears better. You can even check the seal/fit with the info that is automatically added to your iPhone when you set up your AirPods. I had the same problem as you in the past but these ones stay in my ears. I love the new design.
A:Answer5 minutes charge will get you 30-40 minutes of music if the buds are dead (batteries charge faster the lower they are).
Obviously the lower the charge the longer it will take, but they can fill up to full in about an hour.
