Using the headphones
Switching the Bluet ooth on/ off
In instances where using Bluetooth devices are restricted, such as during aircraft
take off of landing, you can use your headphones’ NoiseGard Active noise
cancellation feature (without the hassle of cables) to block out aircraft engine
noise. NoiseGard ANC significantly blocks out ambient noise giving you extra
comfort and rest during a flight.
When using the ANC feature, ensure that the NoiseGard ANC is switched on. To
switch the NoiseGard ANC on in full or adaptive mode, see page 27.
You can also play higher resolution music mid-air, without Bluetooth, by
connecting your headphones to your smartphone or device using the USB cable.
X Push the Bluetooth switch on/off to enable or disable the Bluet ooth connec-
tivity from the headphones.
– Switch the Bluetooth on “I” if you want to use the wireless features of
the headphones, e. g. pairing another set of headphones to the device or
listening music wirelessly
– Switch the headphones off “0” if wireless transmission is not allowed or
restricted, e. g. during aircraft take-off and landing
