   • 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 11, 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 B5 in the Bluetooth list on your device.
4. When paired you will hear the audio feedback 🔈Connected.

If B5 has previously been paired with your preferred device, simply turn on the headset and it will automatically connect, so long as Bluetooth is activated on the device and B5 has not been paired with a different device more recently. 

Device compatibility

B5 uses Bluetooth version 6.0 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 B5 and connected device outdoors to see if the interference clears.

Pairing with multiple devices

B5 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 B5 in the Bluetooth list which pairs it with that device instead. However, some devices require B5 to be disconnected from the previous device entirely before they can be paired. It’s not possible to keep B5 connected to several devices at the same time, such as a laptop and smartphone simultaneously.
