A:AnswerHi Tony, that is a replacement silicone eartip, the removable part designed to aid comfort/fit of the product. You cannot purchase actual singular earbuds. If you lose or damage one, the entire product will need to be replaced as they are paired together during the manufacturing process.
A:AnswerWe can only officially suggest using the StayHear+ Tips with the Bose product they were manufactured for. However, if you wish to use just the eartips to sleep in, you're welcome to try them and see if it helps.
A:AnswerYou will charge the earbuds with these in the charging case and connected to power with the provided charging cable. To download the Bose Music app, a smartphone will be required.
