Noise cancelling headphones were once reserved for frequent flyers and audiophiles. In 2025, they're essential kit for anyone who works from home, commutes, or simply wants to focus. Here's how they work and which ones to buy.
How Active Noise Cancellation Works
ANC headphones use microphones to pick up ambient sound, then generate an "anti-noise" signal that cancels it out before it reaches your ears. The result: background noise dramatically reduced without you having to crank the volume.
ANC vs Passive Noise Isolation
Passive isolation physically blocks sound using ear cups and padding. ANC actively eliminates it electronically. The best headphones combine both for maximum quiet.
Best ANC Headphones of 2025
Sony WH-1000XM6
The gold standard of ANC. Exceptional noise cancellation, superb sound quality, and 30+ hours battery life. The go-to recommendation for most people.
Bose QuietComfort Ultra
Bose's spatial audio implementation is class-leading. Slightly less battery life than Sony but marginally better comfort for long sessions.
Apple AirPods Max (USB-C, 2024)
Luxury build quality and seamless Apple ecosystem integration. Best if you're deep in the Apple ecosystem.
Anker Soundcore Q45
The budget pick — solid ANC and good sound at under £60. A remarkable value proposition.
What to Consider When Buying
- Battery life (aim for 25+ hours)
- Transparency mode quality for safe outdoor use
- Comfort for extended wear
- Multipoint connection to pair two devices at once
