Did you know that the noise cancellation (NC) function can be used without playing back music?
It can be a handy feature to block out background sounds in noisy places such as a train or a plane.
However, your headphones will go to [Auto Power Mode] if no music is played back after 5 mins.
To avoid this, you can use the bundled stereo cable that was provided when purchasing your product.
Keep it connected to a playback device such as a mobile phone or an MP3 Player without actually playing music.
This will prevent the headphones going into [Auto Power Mode].
That way you can use the NC function on its own and enjoy a moment of absolute silence.
