Noise cancellation is not working

The combination of both active and passive noise reduction technologies in your headphones is desgined to block out most sounds but may not block out everything. You may still hear higher pitched sounds like sirens and even human voices, although the volume of these sounds should be dramatically reduced. If you feel you are not geting any noise reduction with your headphones, here are a few steps you can try.

Switch to Quiet mode or disable ActiveSense

New Modes and the ActiveSense feature was added in the Bose Music App, versions:
  • iOS: 5.0.2
  • Android 5.0.1
  • QC Earbuds firmware version 2.0.7


In Aware Mode, ActiveSense™ technology automatically adjusts the noise cancellation so you can enjoy your music comfortably. If the noise cancelling suddenly turns off due to loud noises around you, switch to "Quiet" mode or disable ActiveSense. See

Remove the earbuds from your ears and then reinsert them

Removing and reinserting the earbuds can reactivated the noise cancelling.

Make sure you are in "Quiet" mode.

Check your settings in the app to make sure you are in "Quiet" mode not "Aware" mode. In "Aware" mode, external mics on the headset feed outside sounds into the headset and therefore can make other noises or the noise floor seem louder.
See Setting the adjustable Active Noise Cancellation mode.

Be sure the earbuds are being worn properly

Proper fit is important for product comfort and performance. If the earbuds do not fit properly or the orientation is incorrect it could lead to poor audio or mic performance. See, Wearing and adjusting your earbuds for more details.

Make sure in-ear detection is enabled in the Bose Music app

You can access this option from the Settings menu. See In-Ear detection for more information.

Do you hear static or distorted audio while in noisy environments?

If the audio is distorted while in loud environments such as construction zones or during take off on an airplane, see Crackling sound heard in noisy environments.

Try a different noise cancelling level.

You can adjust the noise cancellation levels using the slider in the Bose Music app.

Try different levels and see if the noise cancellation is improved. For more information see, Setting the adjustable Active Noise Cancellation mode.
