Before getting started
⚠️ Sudio A3 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/turn on.
The earbuds will likely have some existing battery charge, however it is recommended to fully charge A3 before using it for the first time.
Turning A3 on or off
A3 powers up as soon as the earbuds are removed from the charging case, as indicated by the LED lights on the earbuds and the audio feedback 🔈 Power On.
Similarly, A3 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 7 seconds on either earbud.
Pairing with a device
A3 enters pairing mode when the earbuds are removed from the charging case. Open the Bluetooth settings on your device and wait for A3 and the device to locate each other, then select Sudio A3 when it appears in the list. You will hear 🔈 Pairing Successful, confirming that the devices are paired with each other!
Charging the batteries
There are three batteries in total on A3; one in the charging case and one in each earbud.
The A3 earbuds charge their batteries automatically when placed inside the charging case. Make sure to first remove the protective film which is covering the charging connectors.
The A3 case is charged with a Type-C USB-cable. When the case is charging, you will see a light on the front of the charging case. 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.
Restoring A3 to factory settings
If A3 starts behaving unexpectedly, or if you wish to remove the connection between A3 and the connected device, you can perform a factory reset to restore your Sudio A3 to its original settings. This will reset the connection between your paired devices, as well as the connection between the two earbuds.
1. Take the earbuds out of the charging case.
2. Wait until the earbuds have gone through the voice feedback saying: 🔈 Ready to pair, find your Sudio product in the Bluetooth list of your device. Then proceed with pressing and holding both touch points on the earbuds for 6-8 seconds until you hear Power Off.
3. Release the touch button, and once again hold both touch points of the earbuds for 6-8 seconds until you hear 3 clicking sounds.
4. Leave the earbuds out of the case and close to one another for 20 seconds so they can resynchronize.
5. Place the earbuds back in the case and close the lid and allow 1 minute before using the earphones again.
A3 powers up as soon as the earbuds are removed from the charging case, as indicated by the audio feedback 🔈 Power On. When pairing A3 for the first time, you hear 🔈 On followed by 🔈 Ready to pair, find your Sudio product in the Bluetooth list of your device.
⚠️ Sudio A3 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 A3 with a device
- Remove the A3 earbuds from the charging case and fit them inside your ears.
- Go into the Bluetooth settings on your device. The A3 earbud LED lights are flashing white 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 A3 in the Bluetooth list on your device.
- When paired you will hear the audio feedback 🔈 Connected.
If A3 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 A3 has not been paired with a different device more recently.
Device compatibility
A3 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 A3 and connected device outdoors to see if the interference clears.
A3 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
A3 can remember up to 10 paired devices, which means that you don't have to follow the pairing step every time you switch between devices. When A3 is turned on, it will automatically connect to the device most recently connected.
If you want to reconnect to one of your previously paired devices, please disconnect Sudio A3 first from the device you are currently using, and click "Sudio A3" in the list of the next device you want to connect.
Sudio A3 supports multi-pairing, but you can only play audio from one device at a time. (Multi-point connection is not supported.)
