Ett 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 USB Type-C cable is used to charge the case.
⚠️ Sudio Ett 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 charge.
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.
While ANC is activated, the earbuds can be used for approximately 4 hours on one charge, with up to 20 hours in total before the case needs to be recharged.
Each battery takes approximately 60 minutes to fully charge. Sudio Ett also supports quick charging, 15 minutes of charging gives 1 hour of playtime.
The Ett case can be charged with a USB Type-C cable but wireless charging is also supported. We recommend using the Sudio cable included in the package, however, other third-party USB Type-C cables may be compatible too.
Our product Sudio Ladd+ is compatible with Ett for wireless charging.

There are four LED lights on the front of the charging case.
The LED lights on the charging case indicate the remaining battery level of the charging case. The LED lights will be on when you take out the earbuds or put them back into the charging case.

Charging the earphones in the charging case
Put the earbuds inside the case in order to charge their individual batteries.
- When the left earbud is placed inside the case, the left-most LED light on the case will light up for a few seconds, indicating that the left earbud is connected to the case and charging successfully.
- When the right earbud is placed inside the case, the right-most LED light on the case will light up for a few seconds, indicating that the right earbud is connected to the case and charging successfully.
- If any or both of the earbuds are fully charged when they are placed inside the case, the LED lights on the case remain turned off.
You can also check the remaining battery of the Ett earbuds on your mobile device.

For Android devices, you are able to see the battery icon on the screen, there is also a variety of third-party Android app for reading battery levels on connected devices.
If Sudio Ett is not charging properly
In some cases, the charging pins inside the case scratch the receiving pole on the earphone, leaving residue that could potentially break the connection. Gently wipe the charging pin and receiving pole with a dry cloth or a swab and try charging the earphones again. The Sudio Care Kit is ideal for this, as it comes with all tools necessary to keep your Ett in tip-top condition!
If the earphones lose battery faster than usual, follow the instructions below:
- Take out both earphones from the charging case and charge the case with the included cable separately until full.
- Make sure the cable is fully inserted into the case and that there is no dust or dirt blocking the port. Note that inserting the cable forcefully can cause permanent damage to the cable and/or case.
- Use the charging cable included in the product packaging and check that the cable is working correctly.
- Try to get power from a different source i.e. laptop charging port or from a wall outlet.
- If you have other Type C USB-cables, consider trying these and see if there is any difference.
