A2 - User guide - Connectivity & Pairing

Sudio A2 enters pairing mode immediately when the earbuds are removed form the charging case. When pairing A2 for the first time, you hear 🔈 On followed by 🔈 Ready to pair, find your Sudio product in the Bluetooth list of your device.

⚠️  Sudio A2 is delivered with a red 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 A2 with a device

  1. Remove the A2 earbuds from the charging case and fit them inside your ears.
  2. Go into the Bluetooth settings on your device. 
    • 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.
  3. Locate and select Sudio A2 in the Bluetooth list on your device.
  4. When paired you will hear the audio feedback 🔈 Connected.

If A2 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 A2 has not been paired with a different device more recently. 

Device compatibility

A2 uses Bluetooth version 5.2 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 A2 and connected device outdoors to see if the interference clears.

A2 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

A2 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 A2 in the Bluetooth list which pairs it with that device instead. However, some devices require A2 to be disconnected from the previous device entirely before they can be paired. It’s not possible to keep A2 connected to several devices at the same time, such as a laptop and smartphone simultaneously.
