Charging

Charge the Earbuds:

When you hear a voice prompt "battery low", place the earbuds into the charging case to charge. Charging typically takes about 1 hour for a full charge. During charging, the LED on the earbud will illuminate RED. When fully charged, the LED will turn off.

Charge the Charging Case:

A fully charged case can charge the earbuds 5-6 times, providing up to an additional 24 hours of playtime.

When all the LEDs on the case flash WHITE rapidly about 5 times every 20 seconds, the case needs recharging (takes about 2.5 hours).

Use a DC 5V / 0.5-2A USB wall charger, car charger, or computer USB port with the included Micro USB cable to charge the case.

It also shows the LED indicators on the case representing battery levels (25%, 50%, 75%, 100%) during charging. The LED flashes white based on the battery level and stays white when fully charged until the cable is removed.
