Why does the charging light keep flashing blue?
If [the] charging light continues to flash blue for an extended period of time, or remains solid blue, the Eargo is not inserted correctly. Remove and re-insert the Eargo.
You will know you’re all set when the charging lights under the Eargo devices remain solid white, and the indicator lights on the outside of the charger start scrolling.
