The noise cancelling is excellent for noisy work environments.

in noisy environments (e.g. commuter train)

If the above does not resolve the issue then it would need to be determined if the issue is the environment or one of the components that is causing the issue

(It can take ten to fifteen seconds.)As far as active noise cancellation goes, it may not be adequate enough for some, but I find that it does improve my listening environment.

The call quality is okay even in a moderately noisy environment

In a semi quiet environment these work perfectly, at home while using my

I'm dead to the world however in louder environments they just don't do enough for me

In terms of high-quality plastics mixed with metal bones, they are more a peer to the less expensive Bose and Sony; the B&O clearly wins in build and material quality
