The Sony WH-1000XM6 and Bose QuietComfort Ultra Headphones are the two best noise-cancelling headphones money can buy. If you're trying to decide between them, stop reading generic "it depends" reviews. Here's the actual answer.
Sony takes the crown with better sound quality out of the box, class-leading 40-hour battery life (up from 30 hours on the XM5), improved noise cancellation that now matches Bose, and a lower $349 street price. The XM6's new driver design with carbon fiber composite diaphragms delivers noticeably more detail and bass texture. Bose still wins on pure comfort, but Sony wins everywhere else.

| Weight | 248g | 250g |
| Codec Support | LDAC, AAC, SBC, LC3 | aptX Adaptive, AAC, SBC |
| Bluetooth | 5.4 | 5.3 |

| Quick Charge | 3 min = 3 hours | 15 min = 2.5 hours |
The XM6 is a meaningful sonic upgrade over the XM5. Sony's new carbon fiber composite diaphragm delivers tighter bass with less bloat, cleaner mids, and more extended treble. Compared to the Bose QC Ultra, the Sony sounds more detailed and balanced across all genres. Jazz and acoustic music reveal the difference most clearly — instruments have more separation and texture on the XM6.
The Bose QC Ultra sounds warmer and more relaxed. Some listeners prefer this, especially for podcasts and casual listening. But if you care about audio fidelity, the Sony is the better headphone. LDAC support at 990kbps from an Android device pushes the gap even further — the Bose tops out at aptX Adaptive's 420kbps.
For years, Bose held the ANC crown. With the XM6, Sony has finally pulled even. Both headphones effectively silence airplane cabin noise, office chatter, and city traffic. The Bose is marginally better with irregular, variable sounds (barking dogs, construction). The Sony is marginally better with low-frequency drone (engines, HVAC). In practice, you won't notice the difference. Call it a tie.
The QC Ultra is the more comfortable headphone for extended wear. The earcups are slightly deeper, the headband pressure is more evenly distributed, and the protein leather stays cooler. The Sony XM6 improved over the XM5 with wider earcups and softer padding, but after 3-4 hours, the Bose still feels noticeably less fatiguing. If you wear headphones 8+ hours a day at a desk, this matters.
Buy the Bose if comfort is your top priority. If you're a frequent flyer who wears headphones for entire trans-Atlantic flights, or an office worker who keeps them on all day, the QC Ultra's superior ergonomics justify the $80 premium. The Bose Immersive Audio spatial feature is also genuinely impressive for movie watching.
For everyone else — commuters, music enthusiasts, casual users — the Sony XM6 gives you better sound, longer battery, and a lower price. That's a hard combination to beat.
Apple AirPods Max (2nd gen, $549) — Premium build, great ANC, perfect for Apple ecosystem users. But the price is hard to justify over either of these.
Sennheiser Momentum 4 ($299) — Audiophile-leaning tuning, 60-hour battery. Weaker ANC, but spectacular sound for the price.
Sony WH-1000XM5 ($248 refurbished) — Still excellent. If budget is tight, the XM5 at $100 less than the XM6 remains a phenomenal value.
Yes for most people. The XM6 offers better sound quality, 40 hours of battery life vs 24, and costs $80 less. Bose wins on comfort, but Sony wins on nearly everything else.
They are extremely close. The Bose QC Ultra had a slight edge previously, but the XM6 has closed the gap with improved 8-mic ANC processing. Both are class-leading.
Yes, the WH-1000XM6 supports LDAC, AAC, SBC, and LC3 codecs, giving you high-resolution wireless audio on compatible devices.
