Before getting started
⚠️ Sudio T3 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.
The earbuds will likely have some existing battery charge, however it is recommended to fully charge T3 before using it for the first time.
Turning T3 on or off
T3 powers up as soon as the lid on the charging case is opened, as indicated by the LED lights on the earbuds and the audio feedback 🔈 On.
Similarly, T3 is turned off when placing the earbuds back into the case.
You can also use the touch controls to power the earbuds on or off. Do this by holding the touch control for 5 seconds on either earbud.
Pairing with a device
T3 enters pairing mode when opening the lid on the charging case. Open the Bluetooth settings on your device and wait for T3 and the device to locate each other, then select Sudio T3 when it appears in the list. You will hear 🔈 Connected, confirming that the devices are paired with each other!
Charging the batteries
There are three batteries in total on T3; one in the charging case and one in each earbud.
The T3 earbuds charge their batteries automatically when placed inside the charging case, this is indicated by the LED lights on the earbuds. Make sure to first remove the protective film which is covering the charging connectors.
The T3 case is charged with a Type-C USB-cable. When the case is charging, you will see a light below the charging port (where the cable is inserted). It is recommended to use the Sudio Type-C USB-cable that's included in the package, but the charging case may be compatible with third-party Type-C USB-cables as well.
T3 - User guide - Connectivity & Pairing
Sudio T3 enters pairing mode immediately when opening the lid on the charging case. When pairing T3 for the first time, you hear 🔈 On followed by 🔈 Ready to pair, find your Sudio product in the Bluetooth list of your device.
⚠️ Sudio T3 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.
Pairing T3 with a device
- Remove the T3 earbuds from the charging case and fit them inside your ears.
- Go into the Bluetooth settings on your device. The T3 earbud LED lights are flashing white and orange while scanning for available devices.
- For iOS (iPhone), go to the Settings app and select Bluetooth.
- For Android, go to the Settings app, then select Connections followed by Bluetooth.
- For Windows 10, click on the Start button, select Settings followed by Devices, and then Bluetooth and other devices.
- For macOS, go to the System Preferences app and select Bluetooth.
- Locate and select Sudio T3 in the Bluetooth list on your device.
- When paired you will hear the audio feedback 🔈 Connected.
If T3 has previously been paired with your preferred device, simply remove the earbuds from the charging case and they will automatically connect, so long as Bluetooth is activated on the device and T3 has not been paired with a different device more recently.
Device compatibility
T3 uses Bluetooth version 5.4 which is compatible with a wide range of Bluetooth devices. The paired device does not need to be the same version, but similar versions are more likely to maintain a strong connection.
Signal interference
Some wireless devices may interfere with each others' signals, such as WiFi-routers, smartwatches, other Bluetooth devices, etc. If they operate within the same frequency, you may experience interference such as dropped sound and glitching. The easiest way to locate the cause of interference is by maintaining one connection between devices at the same time or take your T3 and connected device outdoors to see if the interference clears.
T3 can be up to a maximum of 10 meters (32 ft) from the paired device, but the connection may break if they are blocked by walls or similar objects.
Pairing with multiple devices
T3 can remember up to 10 devices and will pair automatically with the last used device. In most cases, you can switch between devices by selecting Sudio T3 in the Bluetooth list which pairs it with that device instead. However, some devices require T3 to be disconnected from the previous device entirely before they can be paired. It’s not possible to keep T3 connected to several devices at the same time, such as a laptop and smartphone simultaneously.

T3 - User guide - Care and cleaning
Cleaning your earphones on a regular basis will ensure the best possible sound performance and prevent them from wearing out sooner than expected.
Sudio T3 features silicone ear tips with a built-in mesh net, protecting the earbuds from dirt, grime (and the notorious earwax), all while sitting comfortably in your ears. These ear tips can be removed from the earbuds and cleaned with water or a cotton swab. Avoid hot water though, as this can distort the size and shape of the ear tips.
Use only a slightly damp cloth when cleaning the earbuds and/or case. You can also use a fine brush or cotton swab to gently clean inside the case, avoiding damage to the charging connectors (copper pins). While the T3 earbuds and case are sweat- and splash-proof, subjecting them to high moisture levels could lead to permanent water damage.
Psst, the Sudio Care Kit is ideal for regular maintenance and includes all the tools you need to keep your Sudio earphones in shape!
Keep in mind that with time, some discoloration may eventually appear. This is most common if the earbuds or charging case continue to come in contact with dirty surfaces or materials over extended periods of time.

T3 - FAQ - Can I use one earbud at a time?
Yes, you can use one T3 earbud on its own for both playback and calls. Both earbuds have the same components (speakers and microphones), which means that you can use either the left or right earbud at your leisure.
To ensure a stable connection, always keep the unused earbud inside the charging case.
It’s always a good idea to charge both earbuds until full after having used them separately to maintain the same battery levels.
T3 - FAQ - Does T3 support wireless charging?
No, T3 does not support wireless charging through Q1-technology or similar. Charge your T3 case by inserting a Type-C USB-cable and connecting it to either a USB-port or to a wall socket via an adapter.
We recommend using the Sudio cable included in the product packaging, however other third-party Type-C USB-cables may be compatible too.
