You can pair up to seven Bluetooth devices with your wireless headset. Once you pair the first device, simply initiate the pairing mode of your headset to pair another. While your wireless headset can store up to seven devices, it will only connect to and stream audio from one device at a time.
See answer 360023242194 for help with pairing Bluetooth devices with your headset.
NOTE: When switching from one device to another, make sure you disconnect from the last device before connecting to the next one (see your Bluetooth device's documentation for help).
