Ear (2) can connect with two Bluetooth devices at the same time e.g., mobile phones and PC.
Once Ear (2) is connected to device A , you can connect to device B in Bluetooth Settings, so long as it has previously been connected to Ear (2). Now both device A and device B are connected together.
Note: if Ear (2) is connected to two devices, only the sound from one device can be played.
After the device connections have been established, you can select or switch devices in "Dual Connection" settings via the Nothing X App.*
*For Nothing Phone (1): all device customisations are already integrated into the settings of Nothing OS version 1.1.4 and higher.
