A:AnswerNo they are not. You can buy silicone sleeves that help a little, found them on Amazon. My issue is they start to hurt after a few hours of continuous use. I feel they are a bit large for mine but the sound is awesome. They are exactly like the ones that come with the iPhones and other Apple products, just wth small stems instead of wires:)
A:AnswerAs long as your music isn't ridiculously loud, yes. Also if you only have one in, that also helps. Switching between the two AirPods keeps the other one charged and lets the batteries not drain at the same time, also.
A:AnswerMy dad plans to get them and he has the Samsung galaxy Note 8. Although not all features work he loves the sound quality and will be getting them soon.
