A:AnswerOur JBL Reflect Mini NC only have Bluetooth, it has no GPS in order to find it using an app so we advise you to keep it in the charging case at all times when not in use to avoid losing it.
A:AnswerMine have the same issue. And sometimes the earbuds will go dead in the case because they are constantly connected even though I'm not using them. I will never buy another set of these. They are expensive and should work better.
