Two Bluetooth devices can be simultaneously connected to the headphones, but of these only one device can be used to listen to music or make phone calls at any time. It is convenient to connect devices that you use frequently so that you do not need to re-connect each time you want to switch devices.

When pairing is completed and the Bluetooth connection is established, the Bluetooth LED lights for approximately 5 seconds.
