Even in quiet environments, my girlfriend can't even hear me when I talk through them

n’t take public transportation or work in a noisy environment.

The noise cancellation works better than I had expected even in noisy environments (i.e. data center, airliner, etc.)

The noise cancelling is excellent for noisy work environments.

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

(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.

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

In a quiet environment, the person on the other end thinks I sound great; in a car, it is not as good as holding a phone up to your mouth (again, riding, not driving).

If the issue is not present in the new environment then that would indicate that the components are fine and the original environment (or something in the original environment) is the issue

but I prefer my old Bose QC15 for noisy environments

I am in a very noisy work environment, so noise canceling was the primary driver for this purchase

The only issue I have is that the phone call performance is poor in noisy environments

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

These issues aside, the headphones are still fantastic and I highly recommend them to music lovers and those who are bothered by noisy environments.

This would be nice to have when using them at work or in other relatively quiet environments

The call quality is okay even in a moderately noisy environment

i didn't hear any of the grinding or background noise or music, and this is a very noisy environment.

These are the only headphones I've owned that are suitable for noisy environments

in noisy environments (e.g. commuter train)

so if you already have good headphones you may not be as blown away by these as I

Some fault the B&O for having finnicky touch controls; these have no touch controls and only 2 buttons: on/off, vol up/down

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

n’t had any issues chagring other than trying to decipher the LED indicator color meanings, but after quick consult of the Sennheiser website and instruction
