Bring your wireless JBL in ear earphones safely into the JBL Charging Case. In the case is a battery with which you provide the earplugs with 16 hours of extra playing time. Are you in a hurry? After fifteen minutes of charging, you can use your earbuds for a whole hour to listen to music. On the case is LED lighting, so you can easily see how full the battery of the case is. Do not want to charge the earbuds, but just store them? Then switch off the charging function with button on the inside of Charging Case.
