Aren't ear-plugs noise cancelling? What if they just put tiny speakers inside ear-plugs and bypassed the whole active noise cancelling component?

- Erwin 8y agoThat's pretty much the venerable Etymotic which also have the best isolation as per that site: https://www.rtings.com/headphones/tests/isolation/noise-isolation-cancellation-passive-active https://www.rtings.com/headphones/tests/isolation/noise-isol... For me, they're not comfortable for more than 3 or so hours while I can have either The QC30 or HD800S on all day.
- diffeomorphism 8y ago> Aren't ear-plugs noise cancelling? No, they are isolating. Canceling is an active process using destructive interference of sound waves. Since it is a different mechanism you have quite different properties. For example size/material/fit on ear have different constraints and you can selectively filter out different frequencies (many noise canceling headphones allow you to let voices through for example, or sirens/warning noises).
