This is the charging case for the AirPods Pro (1st generation). Additional information about this product: ======== * The charging case itself works normally. * There are stains and scratches due to aging, so please judge from the photos. * "Bonus" includes the left earphone. * When the left earphone's noise canceling is turned on, a "shhh" sound can be heard, so it cannot be used unless noise canceling is turned off. * This is the 1st generation, so a Lightning cable is required for charging. ========
