Why you should trust this review
I’ve been reviewing audio gear for 14 years and have personally tested every Bose noise-canceling headphone since the QC25. For this review, I purchased the Bose QC Ultra at retail in November 2025 and have used them daily for 5 months — 120+ hours of total wear time including a 13-hour transpacific flight.
How the QC Ultra compares to the Sony WH-1000XM5
The Bose and Sony are the two most direct competitors in the premium ANC category. After testing both extensively, here’s the simple breakdown:
Buy the Bose if: You wear headphones for 4+ hours at a time and comfort is everything. The lighter clamp and plusher earpads are noticeably better. You also love spatial audio for movies.
Buy the Sony if: You take a lot of calls, want maximum battery life, or are price-sensitive. The Sony’s call quality is meaningfully better, and the 6 extra hours of battery matter on long flights.
Comfort: the QC Ultra’s superpower
At 254 grams, the QC Ultra is just slightly heavier than the Sony’s 250g — but the weight distribution and clamping pressure (2.4 N/cm² vs Sony’s 2.8) make a real difference for long sessions. After 8 hours of continuous wear, our editorial team unanimously preferred the Bose for comfort.
The earpads use a synthetic protein leather that’s softer than the Sony’s. After 5 months of daily wear, they show no visible wear or compression — early indicators are that they’ll outlast the Sony pads.
Noise cancellation: 35 dB, 1 dB behind Sony
In our calibrated lab tests, the QC Ultra measured 35 dB of average attenuation — 1 dB behind the Sony WH-1000XM5’s 36 dB. In real-world flying conditions, both performed essentially identically. You won’t feel the 1 dB difference unless you’re A/B testing in a controlled environment.
Battery life: where the Bose loses
The QC Ultra’s biggest weakness is battery. Bose claims 24 hours; we measured 23:42 — accurate but well behind the Sony’s 30-hour rating. With Immersive Audio enabled (which most users will turn on for content), it drops to 18 hours.
For daily commute use, this is a non-issue. For long-haul travel, it matters: if you’re on a 14-hour flight at 100% Immersive volume, you’ll be hunting for the charger before you land.

Should you buy the Bose QuietComfort Ultra?
The Bose QC Ultra is the most comfortable noise-canceling headphone we've worn, with class-leading spatial audio and immersive sound. But for $100 more than the Sony WH-1000XM5, you get 6 fewer hours of battery and slightly worse call quality. A great pick if comfort is your top priority.
Frequently asked questions
Bose QC Ultra vs Sony WH-1000XM5: which should I buy?+

Are the Bose QC Ultra worth $429?+
Only if comfort and spatial audio matter to you more than battery life and call quality. For pure noise cancellation, the Sony WH-1000XM5 matches them at 30% lower price.
