QC25 Noise Cancelling less powerful over time

I have found that the effectiveness of the noise canceling on my QC25's has decreased over time (even with new batteries). Is that normal? When they were new, it would drown out someone talking next to me. Now I can still clearly hear them with the noise canceling turned on.

Hello gscott133,


Thanks for posting and welcome to the Bose Community.


We're sorry to see your noise cancelation is not working as good as it used to, but we'll be happy to help.


We would suggest contacting technical support over the phone for service since you have also tried new batteries as well.


If you go HERE, select your region, scroll to the bottom of the page, choose "Contact Us" and a phone number will be displayed. 


Kind Regards,

Joel - Community Support
