The level of noise cancellation on these headphones is not adjustable.
Sorry, there was a problem. Please try again later.Just have read a review and apparently the ANC can be ON/OFF with Volume buttons and Pairing with Power ones.... Check the below link: http://economictimes.indiatimes.com/magazines/panache/sennheiser-hd4-50-btnc-review/articleshow/58608380.cms
Sorry, there was a problem. Please try again later.It isn't user-adjustable. However, from my own personal experience it seems to compensate for the amount of ambient noise to allow just enough in to be aware of your surroundings so you won't get run over on your daily commute. It doesn't detract from the listening experience at all. The fidelity is better than its competitor in my honest opinion.
