Sony WH-1000XM6 vs Bose QuietComfort Ultra 2: the 2026 flagship ANC showdown
Sony released the WH-1000XM6 in September 2025 ($449 MSRP) and Bose released the QuietComfort Ultra 2 in October 2025 ($429 MSRP). These are the two most-bought premium over-ear ANC headphones in North America. They're within $20 of each other, both sound excellent, and both cancel noise brilliantly. Choosing between them comes down to three non-negotiables: ANC depth (Sony wins), comfort for all-day wear (Bose wins), and ecosystem tie-in (Sony is more platform-agnostic).
Spec breakdown
| Spec | Sony WH-1000XM6 | Bose QC Ultra 2 | Notes |
|---|---|---|---|
| Driver | 30 mm carbon fiber composite | 35 mm neodymium | Bose driver is bigger, Sony's is stiffer |
| ANC depth (broadband) | -38 dB | -35 dB | Sony wins by 3 dB, most in low freq. |
| Bluetooth codec | LDAC · LC3 · AAC · SBC | aptX Adaptive · AAC · SBC | LDAC for high-res Android; aptX for low latency |
| Multipoint | 2 devices | 2 devices | Both work well |
| Battery (ANC on) | 30 h | 24 h (20 h w/ Immersive) | Sony +6 h |
| Fast charge | 3 min = 3 h | 15 min = 2.5 h | Sony's is faster per minute |
| Weight | 249 g | 253 g | Essentially identical |
| App EQ | 12-band parametric | 9-band sliders | Sony more granular |
| Head-tracked spatial | 360 Reality Audio (limited) | Immersive Audio (any source) | Bose spatializes everything |
| Call mics | 8-mic beamforming | 6-mic array | Bose is slightly clearer on calls |
| USB-C wired support | Yes — DAC mode | Yes — analog only | Sony does digital over USB-C |
| Case | Hard shell, folds flat | Hard shell, doesn't fold | Sony more portable |
ANC quality — the metric they're both designed for
Rtings' mic-array testing of both headphones with identical pink-noise sources at 1 meter:
| Frequency band | XM6 attenuation | QC Ultra 2 attenuation | Winner |
|---|---|---|---|
| 20–200 Hz (engine/HVAC rumble) | -28 dB | -22 dB | Sony by 6 dB |
| 200 Hz–2 kHz (voices) | -21 dB | -20 dB | Tie |
| 2–8 kHz (clicks/keyboard) | -15 dB | -14 dB | Tie |
| Broadband 20 Hz–20 kHz | -38 dB | -35 dB | Sony by 3 dB |
On planes, buses, subways, and open offices with HVAC, Sony is audibly quieter. In a coffee shop or cafe with mixed conversation, they're close enough you'd need an A/B switch to tell. If you fly 30+ times a year, Sony is the right buy. For office and commute noise, either works.
Sound signature — they tune differently
Sony XM6 ships with a slightly V-shaped signature (boosted bass + treble, pulled-back mids) that flatters pop and electronic music. The 12-band EQ in the Sony Headphones Connect app lets you flatten it toward neutral or pull out the bass for acoustic listening. Measured on a GRAS fixture, XM6 is ±3 dB of Harman Target from 50 Hz to 8 kHz.
Bose QC Ultra 2 ships closer to neutral with a gentle low-mid warmth and slightly recessed upper treble. It handles vocal-forward content (podcasts, jazz vocals, audiobooks) exceptionally well. The app's 9-band EQ is less granular than Sony's but covers 95% of real-world tuning needs.
For critical listening of recorded music: Sennheiser Momentum 4 edges both. For everyday listening with ANC: either is excellent and the choice comes down to taste.
Comfort — where Bose earns its loyal audience
Clamp force: XM6 measures 4.1 N, QC Ultra 2 measures 3.2 N (Rtings clamp-force tests). That 0.9 N difference is significant — Bose is noticeably looser on the head, which matters after hour 3. People with larger heads or who wear glasses report the Sony causing pressure around the temples after 4+ hours; the Bose rarely does.
Ear cushion material: both use polyurethane leatherette. Bose's foam is softer and taller (23 mm vs 19 mm), giving more ear clearance. Sony's foam is denser and traps more heat, which some users like (winter) and others hate (summer).
If you plan to wear them 6+ hours a day at a desk, Bose is the clear winner. For 1–3 hour sessions (commute + workout + flight), both are fine.
Call quality — slight edge to Bose
In a controlled quiet room, call recipients rate both near-identical. In a noisy environment (coffee shop, outdoor wind), Bose's 6-mic array with adaptive noise suppression pulls slightly ahead — voice is clearer and background voices are more reduced. Sony's 8-mic system over-processes in some conditions, producing a slightly robotic sound on the listener's end.
Apple AirPods Max still wins this category if you're on iPhone — neither Sony nor Bose matches AirPods Max's voice isolation. But AirPods Max is $549 and doesn't fold. Different category.
Spatial audio and head tracking
Bose's Immersive Audio spatializes any stereo source using Bose's own algorithm — no Dolby Atmos license required. It works on YouTube, Spotify, podcasts, anywhere. The effect is tasteful, not gimmicky, and drops battery from 24 to 20 hours when on.
Sony's 360 Reality Audio requires 360 RA-encoded content (Amazon Music HD subscription, Tidal HiFi Plus). Most music on Spotify and Apple Music is NOT 360 RA. When you have compatible content, it's spectacular. When you don't (90% of the time), it falls back to stereo.
If you want spatial on everything, Bose. If you want spatial on high-end encoded content only, Sony.
Ecosystem and device switching
Sony Headphones Connect app is best-in-class: 12-band parametric EQ, Adaptive Sound Control (ANC auto-adjusts to activity), voice assistant toggle, button remapping. Works identically on iOS and Android.
Bose Music app is simpler and cleaner but less powerful. 9-band EQ, shortcut assignment, Immersive Audio toggle, QuietComfort preset slots. Also cross-platform.
Multipoint on both connects to two devices simultaneously (say, laptop + phone). Both handle seamless audio handoff when a call comes in on the phone while music plays from the laptop. Neither supports three simultaneous connections.
Price and availability
Sony WH-1000XM6: MSRP $449. April 2026 street price: $399 at Best Buy / Amazon during major sales; $429 on average. Bose QC Ultra 2: MSRP $429. Street $389–$399 during sales; $419 average. Over a 2-year ownership, the price delta is essentially zero.
Decision criteria
- Choose Sony XM6 if: you fly frequently, want LDAC hi-res for Android, prefer detailed EQ, or wear them for shorter 2–4 hour sessions.
- Choose Bose QC Ultra 2 if: you wear them 6+ hours daily, wear glasses, prioritize comfort, or want Immersive Audio on any content.
- Choose neither — buy Sennheiser Momentum 4 ($380) if you prioritize pure sound quality over ANC depth and don't care about spatial.
- Choose neither — buy AirPods Max ($549) if you're deep in Apple ecosystem and want best-in-class call quality.
Frequently asked questions
Which has better ANC for flying?
Sony WH-1000XM6 by 6 dB in the critical 20–200 Hz engine-noise band. This is the one scenario where the difference is clear and consistent.
Do both support multipoint?
Yes, both support simultaneous connection to 2 devices. Neither supports 3.
Is aptX Adaptive on Bose better than LDAC on Sony?
Different strengths. aptX Adaptive has lower latency (gaming, video) and works on more Android phones. LDAC supports higher bitrates (990 kbps vs 420 kbps) for high-res audio if you have a compatible source.
Can I wear either with glasses comfortably?
Both work with glasses; Bose is noticeably better because of the lower clamp force. If you wear thick-framed glasses, try Bose first.
Which has better mic for video calls?
Bose by a small margin in noisy environments thanks to adaptive noise suppression. In quiet rooms they're equivalent.
Do they both fold?
Sony XM6 folds flat (the hinges rotate 90°). Bose QC Ultra 2 does not fold — earcups rotate flat but frame stays rigid. Sony's carry case is ~20% smaller as a result.
Can I use them wired?
Yes, both include a 3.5mm cable. Sony additionally supports USB-C digital input (DAC mode) bypassing the analog path — a real advantage for audiophile use.
