The MW60 Headphones are multipoint compatible, meaning they can connect to more than one device at a time.
To enable multipoint, first enter pairing mode and connect to the first device. Once the first device is connected, enter pairing mode again - the first device will disconnect. Now connect to the second device and power OFF your headphones. Turn the headphones back ON and they will automatically connect to both the first and second devices simultaneously.
To switch between devices when connected with multipoint, simply pause playback on the first device and resume audio from the second - the headphones will swap to the device actively playing audio.
