QuietComfort 35 wireless headphones II | Noise cancellation is not working

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.

Move away from any hard surfaces.

Reflected sound (caused by using the headset close to a hard surface – like a wall) will negatively affect noise cancellation.

Check for and install any available product updates.

On a computer, visit btu.bose.com and follow the instructions to ensure your product has the latest features and enhancements. See Updating the software or firmware of your product.

Be sure the earcups are tightly seated against the head.

Glasses, earrings and hats may prevent the headphone cushions from forming a tight seal around the ear. Remove any of these items and retest the noise cancelling feature.

Be sure the cushions are securely attached to the earcup.

If the ear cushion is not affixed to the ear cup properly, the noise reduction or sound quality may be affected. For more information, see Replacing the ear cushions.

Reset your product.

Much like rebooting a smartphone, your product might need to be reset on occasion to correct minor issues. For more info, see Resetting your product.
