A:AnswerYes, replacement AirPods are available directly from Apple if you were to lose or damage one of the AirPods. I think they charge $99 for one but not totally sure.
A:AnswerGo to bluetooth settings to connect your pods. Apple Music has instructions to connect. It's fairly easy but you have to find "support" in the menu. Airpods come with no instructions because bluetooth (for the most part) is automatic these days and Apple expects that consumers should be aware that instructions are included with Apple Music. Hope that helps.
A:AnswerA skin shouldn’t effect the charging capability of the wireless case most protective cases also don’t inhibit the charging either, check with manufacturer if you have any issues with charging.
