T2 - User guide - Battery levels and management

T2 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.

Before using your T2 for the first time

⚠️  Sudio T2 is delivered with a protective film covering the charging connectors between the earbuds and charging case. The film needs to be removed in order for the earbuds to power on.

Charging and play times

The earbuds can be used for approximately 7.5 hours on one charge (6.5 hours while using Active Noise Cancellation), with up to 35 hours in total before the case needs to be recharged.

Each battery takes approximately 60 minutes to fully charge. T2 also supports quick charge, restoring 2 hours of playtime after 10 minutes of charging.

Charging methods

The T2 case can only 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.

Battery level indicators

There are three LED-lights that indicate the respective batteries' remaining level. The charging case’s indicating light is on the back of the case, below the charging port. The earbuds' indicating lights are below the touch control buttons. 

The LED's light up when the earbuds connect and disconnect to the case and when there is less than 25% battery remaining.

When inserting the charging cable to the case, the current battery level is displayed for 5 seconds followed by a blinking light, indicating that the case is currently charging. 

In some cases, you can also read the battery level on your phone, such as iPhone or Android devices. The level shown is that of the T2 earbuds, not the charging case.
