I work in an office, not and overly loud office, but one where noise cancellation works pretty well

I bought for use on an iPhone, in a noisy office, to make phone calls.

Active noise canceling works well to drown out typical office noise like typing and the like

I look forward to taking these to work to see how they perform in a very noisy office setting, and I will also check them out during an upcoming cross-country flight.============Returned after a few days trial.

I spend all day in a noisy office, and these do a great job of muting the sounds around

Original review:I’m so disappointed with these

Would've preferred USB-C but for this price I'm not complaining at all.
