Best Noise‑Cancelling Earphones & ANC Explained
Why noise‑cancelling?
Active noise cancellation (ANC) uses outward‑ and inward‑facing microphones to detect ambient noise and generate counter‑signals that cancel those sounds. Search interest for “true wireless earbuds with noise cancelling” peaked in March 2025 according to the Accio report, reflecting growing demand for quiet listening in crowded cities, airplanes and offices.

Understanding ANC vs Passive Isolation:
-
- Active noise cancellation generates anti‑noise to cancel external sounds. It works against constant low‑frequency noise like engines or air‑conditioners and consumes battery power.
-
- Passive noise isolation relies on physical barriers (ear tips or over‑ear cushions) to block noise. It doesn’t drain battery but is less effective against low‑frequency rumble.
-
- Hybrid ANC (found in many premium models) combines feed‑forward and feedback microphones for better cancellation across a wider frequency range.
Travel & Work‑from‑Home Tips:
- Use ambient modes when needed: Features such as ambient sound (Samsung Buds2 Pro ) or Transparent Mode allow environmental sounds in so you can hear announcements or colleagues.
- Ensure a proper seal: Select ear tips that fit snugly; ANC performance drops if there’s a gap.
- Manage battery: ANC reduces battery life. charge or carry a portable charger.
