Charging your headphones | Bose Sport Open Earbuds (2021)

Lithium batteries have a built-in auto-off feature when a full charge is reached to prevent the battery from being overcharged. Even while still plugged in, the battery level will have to drop below a certain point to trigger the charging again.

1. Align the charging contacts on each earbud with the charging pins on the charging base.
2. Place the earbuds on the charging base until they magnetically snap into place.
   NOTE: Make sure you place the correct earbud on the correct side of the charging base. Look for the L (left) and R (right) markings on the inside surface of each earbud.
3. Connect the USB cable to a wall charger (not provided).
   
   

CAUTION: Use this product only with an agency-approved power supply that meets local regulatory requirements (e.g., UL, CSA, VDE, CCC). While charging, the earbud status lights blink white. When the battery is fully charged, the status lights glow solid white.

For the best battery performance, store the earbuds on the charging base when not in use.
