Audio input
If you don't want to use the Bluetooth connection, you can also connect your Headphones 7 Bluetooth ANC to your
music player using the audio cable provided. You don't need to switch on your headphones if you want to use the audio
cable. In order for your headphones to work properly, do not let the battery run down completely.
Simply connect the cable provided to the AUDIO INPUT (8) to enable this mode.
Important: You will not be able to control playback from the headphones while this mode is on so you will have to
adjust the volume and switch to the previous/next song from your music player.
ANC (Active Noise Cancelling). System to reduce background noise
Press the ANC button (5) to enable and disable the active noise cancelling mode. The ANC INDICATOR (4) glows when
this option is enabled. You don't need to switch on your headphones to enable this mode.
You can enable ANC on your Headphones 7 ANC while either the Bluetooth mode or AUX mode (audio cable) is enabled.
If you are studying or sleeping on a plane, you can also enable this function while not listening to music to cancel
