The battery-powered charging case stores and charges your sleepbuds while you’re not using them. When the case is empty, allow up to three hours to fully charge the case. When the sleepbuds are inside the case, charging time varies. When the case is fully charged and operating on battery power, you can fully charge the sleepbuds once. A single charge of the sleepbuds allows up to 16 hours of use.
Charging the case
Before charging, make sure the sleepbuds are at room temperature, between 41° F (5° C) and 113° F (45° C). You can use any compatible USB power source to charge the case. For best performance, however, use the provided USB power supply.
Connect the small end of the USB cable to the USB connector on the back of the case
Connect the other end to the USB power supply
Plug the USB power supply into an AC (mains) outlet. If necessary, attach the AC power adapter for your region
Charging the sleepbuds
The sleepbuds charge while they are in the case. Allow up to eight hours to fully charge the sleepbuds. A full charge of the sleepbuds allows up to 16 hours of use.

Place the sleepbud in the case until it magnetically snaps into place. The charging light for the right sleepbud blinks white
NOTE: If the charging light doesn’t blink white when you place the sleepbud in the case, the sleepbud may have been placed in the case incorrectly or your case battery may be depleted. Place the sleepbuds in the case again, then charge the case.
