Before diving into our top picks, let’s clarify the difference between active noise cancellation (ANC) and passive noise isolation.
- Active Noise Cancellation (ANC): Uses built-in microphones to detect external noise and counteract it with anti-noise sound waves. This is the best option for frequent travelers dealing with airplane noise, traffic sounds, or chatty environments.
- Passive Noise Isolation: Relies on the headphone’s physical build and materials to block sound. Over-ear headphones with well-cushioned ear cups offer better passive noise isolation, but they don’t actively cancel out lower-frequency sounds like ANC models do.
For air travel and loud environments, ANC headphones are the superior choice. However, if you’re looking for a budget-friendly alternative, passive noise isolation can still be effective in reducing distractions.
