Connect with a cable
When you use the audio cable, the wireless connection switches off, so you can use your headset offline, for example, during a flight.
Connect the cable to the headset, and the other end to the headset connector on your device.
When you've connected the cable, your headset switches to flight mode. You can only connect the headset to one device at a time.
The headset keys work differently when the headset is used with a wired or wireless connection.
Not all phone models support a cable connection. For these phones, use the wireless connection.
