Bose QuietComfort Ultra
Score: 85/100
Bowers & Wilkins Px7 S3 Black
Score: 86/100Rankings
The Bowers & Wilkins Px7 S3 delivers audiophile-grade sound, strong active noise cancellation and a 30-hour battery, but its 1.1 kg weight and lack of a foldable design make it less travel-friendly. It excels for listeners who prioritize sound fidelity and ANC over portability. Best suited for audiophiles and frequent travelers who value premium build and long endurance.
The Bose QuietComfort Ultra (1st Gen) is an over-ear wireless headphone delivering industry-leading ANC and up to 24 hours of playback. Its bulkier build and lack of water resistance limit active-use scenarios. Ideal for travelers and office workers seeking premium noise cancellation.
