The charging case adopts a large capacity 2600mAh battery that can charge both earbuds an additional 16 times. As a result, both earbuds can obtain a total of 120 hours of continuous playback time.

Once both earbuds are placed back into the charging case and the lid is closed, both headsets will begin charging.
