Things to note:
- Over-the-ear designs provide better noise cancellation.
- On-ear designs are smaller (and therefore take up less room in one's carry-on bag).
- The article didn't review in-ear earphones, which, in my opinion, offer better noise isolation than noise-canceling headphones and are much smaller, but suffer from not being as comfortable for extended use.
But I digress. Audio filtering sometimes even has to be done in the field, which in urban environments can be quite noisy. So, as you can see, audio forensic examiners and audio technicians both can benefit from noise canceling and noise isolating headphones and earphones.
