Quick verdict: Sony for flexibility, Bose for USB listening
At similar prices, the Sony WH-1000XM6 is our starting point for most buyers: it offers finer sound adjustments and lasted longer in one directly comparable battery test. Choose Bose QuietComfort Ultra Headphones (2nd Gen) if USB-C listening matters or its fit is more comfortable on your head.
Both are strong noise-cancelling options. Neither is a waterproof workout headset. This is a research-based comparison, not a Decively hands-on test; evidence and listings checked October 7, 2026.

The differences worth paying for
The Bose in this comparison is the second-generation over-ear model, not the original Ultra or the Ultra Earbuds. Both launched in 2025; this guide reflects their current features in 2026.
| Decision point | Sony XM6 | Bose Ultra 2 |
|---|---|---|
| ANC-on battery claim | Up to 30h | Up to 30h |
| ANC-on independent test | 37h 14m | 27h 12m |
| Sound adjustments | 10-band EQ | 3-band EQ |
| Wired listening | 3.5mm analog | USB-C + analog |
| Power-off analog playback | Yes | No |
| Bluetooth calls / multipoint | Yes / two devices | Yes / two devices |
| Main compromise | No USB audio | Shorter tested battery |
Battery claims: manufacturers. ANC-on rundown and EQ comparison: SoundGuys. Wired connections: Sony and Bose documentation. Figures describe these exact generations.
Noise cancelling and comfort: fit matters more than a tiny lead
There is no convincing universal ANC winner. RTINGS gives Sony a small isolation advantage; SoundGuys describes the difference as practically close. What Hi-Fi? found Bose’s Quiet mode blocked noise more strongly, but preferred Sony’s subtler sensation. That disagreement is a reason to prioritise fit and comfort, not a reason to invent a score.
Android Central reviewer Tshaka Armstrong preferred Bose’s lighter clamping force for long sessions. In an r/bose comparison thread, owners also described different fit preferences. These are individual experiences, not a guarantee that Bose will fit everyone better. Glasses, head shape and earcup seal can change the result.
For music, Sony’s 10-band EQ offers finer adjustments than Bose’s three-band controls. What Hi-Fi? preferred Sony’s sound; that remains a listening preference. Sony uses broad touch gestures, while Bose combines playback buttons with a touch volume strip.
Battery life: look beyond the identical 30-hour claims
Independent ANC-on rundown reported by SoundGuys: 37h 14m for Sony and 27h 12m for Bose. Bars use the same scale; these are not Decively measurements.
Sony and Bose both advertise up to 30 hours with ANC. SoundGuys’ standardised rundown favoured Sony, as the chart shows. Your volume, codec, calls and settings can change that result; neither figure is a promise for every user.
Bose specifies up to 23 hours with Immersive Audio and ANC, or 45 with both off. Sony specifies up to 40 hours with ANC off. Keep the listening mode consistent when comparing battery claims.
USB-C, calls and your phone: the biggest practical difference
Original Decively connection diagram. Sony supports passive analog playback; Bose offers USB digital audio but needs power for wired listening.
Bose can play audio through USB-C; Sony’s USB-C port is for charging. Sony also plays through its 3.5mm cable with the headphones switched off. Bose’s analog connection requires the headphones to be powered, so it is not a passive backup when its battery is empty. Both support Bluetooth calls and two-device multipoint.
There is an important 2026 update: Bose firmware 8.2.20 added 24-bit/48kHz USB audio and PC USB voice calls, supported only in certain VoIP apps. Firmware 10.12.12 adds LE Audio/Auracast in beta on compatible Android and Windows devices, plus improved USB call compatibility. Update first; do not assume an older review describes today’s software, or that every computer, phone or console is supported.
Both work with iPhone and Android. Sony offers LDAC on compatible Android devices; Bose’s aptX Adaptive/Snapdragon Sound features require compatible source hardware. Ordinary iPhone Bluetooth listening uses AAC, not those Android codec features. Choose around your actual phone and work setup, rather than a codec badge.
Which one should you buy at today’s price?
Start with the feature you would miss. If you rarely connect a cable, Sony’s stronger customisation and tested battery advantage are easier to justify. If you regularly listen from a laptop over USB-C, Bose offers something Sony cannot add with an EQ setting. If neither premium option solves your main need, our best wireless headphones guide also covers budget listening, music customization and desk calls.
A meaningful discount can reverse the recommendation. Compare the delivered total, seller, warranty and included bundle, rather than assuming the dearer option is better. The linked Sony US offer includes a Deco Guide; do not pay extra for that bundle if it adds nothing you need.
Choose Sony when charging breaks and EQ matter
The practical all-round pick if its fit works for you and USB audio is unimportant. Check the black/Obsidian bundle and seller terms.
Choose Bose when USB audio or its fit settles the decision
A more useful choice for a compatible wired laptop setup. Confirm “2nd Gen”: our local link check selected the older Diamond 60th Edition on Amazon UK.
A few buying questions
Are these good for flights?
Both are suitable noise-cancelling travel headphones and fold into cases. Fit, battery and your aircraft’s audio connection are more useful tie-breakers than a blanket ANC winner.
Should I upgrade from an older model?
Only if the new feature fixes a real limitation. USB-C listening can justify Bose 2nd Gen; detailed EQ or a different fit can favour Sony. If your current pair already does the job, an upgrade is optional. Our Sony XM5 review and first-generation Bose Ultra review cover those older alternatives.
Will the Amazon link always show the same version?
No. Local matching can change the model or bundle. Confirm WH-1000XM6 for Sony and QuietComfort Ultra Headphones (2nd Gen) for Bose, plus delivery eligibility, before ordering.
