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 you're wearing the earbuds correctly.
A proper fit is important for comfort and sound quality. If the earbuds are not worn properly or positioned incorrectly, audio and microphone performance may be affected. See Wearing and adjusting your earbuds for more details.
Make sure in-ear detection is enabled in the Bose 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?
In very loud settings—such as airplane takeoffs, concerts, emergency sirens, or construction zones—your headphones' noise-cancelling microphones can become overwhelmed, which may cause brief crackling or distortion. This can happen even in Quiet or Aware mode.
It’s similar to when someone talks too loudly into a phone—the sound gets distorted until they lower their voice. Your headphones react in the same way to intense external noise.
This is normal and doesn’t damage the product. To reduce it, try moving away from the loud source when possible. For example, on a plane, sitting farther from the engines can help.
Try a different noise cancelling level.
You can adjust the noise cancellation levels using the slider in the Bose app.
Try different levels and see if the noise cancellation is improved. For more information see, Setting the adjustable Active Noise Cancellation mode.
