The ANC Heavyweight Championship
Sony's WH-1000XM6 and Bose QuietComfort Ultra remain the two reference points for premium noise-canceling headphones. After two weeks of A/B testing, here's how they compare.
ANC Performance
- Sony XM6: 42dB attenuation at 100Hz, adaptive with 8 microphones
- Bose QC Ultra: 40dB attenuation at 100Hz, consistent across environments
Sony's adaptive ANC is more aggressive in consistent noise (airplanes). Bose maintains more consistent cancellation across varied environments.
Sound Quality
Sony's new 40mm carbon fiber driver delivers tighter bass and clearer midrange. LDAC and DSEE Extreme support high-res streaming. Bose's Immersive Audio creates a wider soundstage.
Comfort and Build
After 4+ hours, the Bose QC Ultra remains more comfortable thanks to lighter clamping force and softer cushions. Sony provides better passive isolation from its seal.
Battery Life
Sony wins: 40 hours with ANC on. Bose delivers 24 hours. Both support quick charge — 5 minutes for 3 hours of playback.
Verdict
For maximum ANC and battery life, choose Sony XM6. For superior comfort and consistent ANC, choose Bose QC Ultra.
