Hi, could somebody help - I can't work out how to activate noise cancellation without putting music on - QuietComfort 35 II . thank you in advance. Yana
Thanks for reaching out. Welcome to the community.
When you turn on the QuietComfort 35 II Headphones this will activate the noise cancellation technology.
Do let us know if this appears to not be working.
