D1 has three built-in batteries; one inside the charging case and one in each earbud. The battery inside the case is used to charge the earbuds, while the included Type-C USB-cable is used to charge the case.
Charging and play times
The earbuds can be used for approximately 6 hours on one charge, with up to 30 hours in total before the case needs to be recharged.
Each battery takes approximately 90 minutes to fully charge.
Charging methods
The D1 case can be charged with a Type-C USB-cable, wireless charging is not supported. We recommend using the Sudio cable included in the package, however, other third-party Type-C USB-cables may be compatible too.
