Bring the headset and the Bluetooth device within 1 m from each other.

When you turn on the headset for the first time after purchasing, initializing, or repairing it, the headset enters pairing

mode automatically. When you want to pair a 2nd or subsequent device, press and hold the

button of the

headset for more than 7 seconds to enter pairing mode.

When you pair the headset with devices again after initializing or repairing the headset, information for pairing with

the headset remaining on the iPhone or other device may prevent you from pairing them successfully (iPhone etc.).

In this case, delete the pairing information of the headset from the device, and then pair them again.
