Bose wins on pure noise cancelling — measurably the best in class — plus comfort and calls. Sony wins on battery (30 vs 24 hours), LDAC support, and value at $250–$300 street. Most travelers should buy the Sony; ANC purists who find the Bose on sale at $279–$329 won't regret it.
— THE VERDICT · JUDGEANY EDITORSTwo philosophies of flagship
The Sony WH-1000XM5 and the Bose QuietComfort Ultra (2023, first generation) are the two default answers to "what's the best noise-cancelling headphone?" — but they win for different reasons. Sony is the travel all-rounder: 30-hour battery, 250-gram comfort, LDAC hi-res wireless, and a street price that keeps falling. Bose is the ANC purist: the best-measured noise cancelling on the market, superb comfort, and superb calls — with weaker battery and codec support. We don't run a test lab; this comparison aggregates manufacturer specs, owner reviews, and published expert measurements.
Noise cancelling: Bose wins, measurably
This is the clearest gap between them. SoundGuys' lab measurements put the Bose at roughly 87% ambient noise reduction — the highest recorded in its class — against roughly 84% for the Sony. Owners agree: the Bose silences planes and offices like nothing else, while the Sony is excellent but a half-step behind, especially on deep low-frequency rumble.
Sound and codecs: pick your ecosystem
The Sony plays warmer and bass-heavier out of the box (fixable with its excellent in-app EQ) and offers LDAC hi-res wireless for Android users — but no aptX. The Bose sounds energetic and detailed with CustomTune ear calibration, supports aptX Adaptive (only useful with Snapdragon Sound phones), and offers no LDAC. iPhone owners get AAC either way, so the codec gap matters most to Android users.
Comfort, battery, and calls
Both are light and comfortable — 250 g (Sony) vs ~253 g (Bose) — with owners praising each for all-day wear. Battery is Sony's clear win: 30 hours with ANC on against Bose's 24 (18 with Immersive Audio on), and some Bose owners report fast standby drain. Calls go to Bose by a nose: its mic array earns the most consistent owner praise, though Sony's XM5 closed much of the gap versus the XM4.
Price and the verdict
Neither should be bought at list price. The Sony routinely sells for $250–$300 (list $399.99); the first-gen Bose for $279–$329 (list $429, pushed down by the 2025 second generation). Buy the Sony for the best all-round travel package and value. Buy the Bose if maximum noise cancelling and comfort justify the premium — and make sure you're getting the 2023 first-gen model at the discount price, not the $449 second gen by accident.
