On a flight or in an open-plan office, battery life and comfort matter as much as the noise cancelling itself — a headphone you take off after two hours isn’t doing its job. This guide compares four over-ear models on what their makers actually list.

Sony WH-1000XM6
Sony lists the QN3 processor running 12 microphones, a six-mic beamforming system for calls with wind resistance, and — a change worth noting — a foldable design with a compact magnetic case. Pick it if call quality and the newest ANC matter. Skip it if the XM5 at a lower price covers you.
Sony WH-1000XM5
Eight microphones, Auto NC Optimizer, and Sony’s clearest battery numbers: 30 hours with ANC, 40 without, and three hours from a three-minute charge. Pick it for long-haul flights. Skip it if you need a headphone that folds small — the XM6 listing makes a point of folding; the XM5 listing doesn’t.
Bose QuietComfort
Bose leads with comfort (plush cushions, padded band), Quiet and Aware modes, adjustable bass/mid/treble EQ and up to 24 hours of battery. Pick it for long wear. Skip it if battery is your top priority.
Sony WH-CH720N
Sony’s “lightest wireless noise-cancelling headband ever” at 192 g, with multipoint pairing to two devices. The listing is inconsistent on battery — 35 hours in the title, 50 hours in a bullet — so plan around the lower figure. Pick it on a budget. Skip it if you want the strongest ANC.
What the listings don’t tell you
- ANC strength isn’t quantified. “Best” and “legendary” are marketing words.
- Fit with glasses varies by head shape — buy where returns are easy.
- Codec support for your phone: check the live page if you care about high-resolution audio.
Bottom line
Flights: XM5 for listed battery, XM6 for the newest ANC and calls. Comfort: Bose. Budget and light: CH720N.
