A1 - User guide - Connectivity & Pairing

A1 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. When pairing A1 for the first time, you hear 🔈 On followed by 🔈 Ready to pair, find your Sudio product in the Bluetooth list of your device.

⚠️  Sudio A1 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 A1 with a device

1. Remove the A1 earbuds from the charging case and fit them inside your ears.
2. Go into the Bluetooth settings on your device. The A1 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.
3. Locate and select Sudio A1 in the Bluetooth list on your device.
4. When paired you will hear the audio feedback 🔈 Connected.

If A1 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 A1 has not been paired with a different device more recently. 

Device compatibility

A1 uses Bluetooth version 5.3 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 A1 and connected device outdoors to see if the interference clears.

A1 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

A1 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 A1 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 A1 first from the device you are currently using, and click "Sudio A1" in the list of the next device you want to connect.

Sudio A1 supports multi-pairing, but you can only play audio from one device at a time. (Multi-point connection is not supported.)
