Day to day
How each one fits your routine
For a work laptop, you need a microphone path as well as sound
When your employer allows a wired USB headset but disables Bluetooth, Bose is the one to consider. Before relying on it for work, check its installed firmware and the meeting app you use. Sony’s analog lead carries listening audio, but its phone-call instructions use the phone microphone, so that lead is no replacement for a verified USB conference setup. Sony is still suitable when the approved route is Bluetooth.
Where this comes from
PC USB calls arrived with Bose firmware 8.2.20, along with specific VoIP compatibility limits. Sony documents no USB audio and relies on the source phone microphone for analog calls.
A cable at your desk changes how you get back to the phone
Bose documents a button sequence for leaving USB audio to reach a previously connected Bluetooth device, and for going back to USB afterward. That can work at a desk with computer music and separate phone calls, as long as you do not mind switching sources yourself. Sony turns Bluetooth off once its analog cable is plugged in. Pick Bose for the documented routine of switching from USB to the phone, or keep Sony wireless if getting to the phone comes first.
Where this comes from
In the Bose guide, you press the Bluetooth/Power button to select Bluetooth and press it again to return to USB audio. Simultaneous mixing is not promised, and neither is automatic interruption of USB by every incoming call.

Passive analog stays available on Sony. A Bose audio cable cannot fix an empty battery on its own.

In practice
Differences you will notice
Who wins on cables reverses with the question
On the powered-off analog requirement, Sony wins. On the digital USB requirement, Bose wins.
How we worked this out
Sony has passive analog but no USB audio. Bose Ultra 2 has USB audio but no passive analog.
Bose’s planning margin shifts with Immersive Audio
Its Immersive Audio claim of 23 hours sits seven hours under the standard claim of 30 hours.
How we worked this out
30 − 23 = 7 hours, then 7 ÷ 30 × 100 = 23.3% lower rated duration.
On paper, Sony is lighter by 3.8%
The gap on paper is 10 g and does not amount to a large change in headset class.
How we worked this out
3.8% = (264 − 254) ÷ 264 × 100.
Plug in your setup
Which headphones suit the way you listen?
Start with how you listen. Charging over USB is not the same as playing audio over USB, and some headphones need power even on a cable. These answers are placeholders until you apply your own.

Battery figures are maker claims for the stated mode. They do not reflect measured travel time. Volume, codec, calls and battery age all change runtime. Closed earcups can still leak some sound. Weight alone does not predict comfort. USB audio needs a compatible source and cable. This check does not judge sound quality, mic quality or amplifier power.
Option A

WH-1000XM6

Trade-offs
What each pick costs you
With Sony WH-1000XM6
- Its 30-hour ANC claim matches the XM5.
With Bose QuietComfort Ultra Headphones (2nd Gen)
- A separate 23-hour battery claim applies to Immersive Audio.
Decision guide
How to decide
Pick Sony WH-1000XM6 when an analog cable needs to work on a completely flat battery. Pick Bose QuietComfort Ultra 2 when digital USB-C audio and listening while charging matter to you. Both claim 30 hours of standard ANC playback.
Pick the cable you will really use
USB-C charging, USB audio and passive analog are each a separate capability. Sony handles the dead-battery airplane case, and Bose handles a direct USB-C connection at the desk. Choosing by socket shape alone could lead you to the wrong purchase.
Thirty hours does not decide between them
Because the ANC figure is the same, battery capacity cannot break the tie. Bose’s Immersive Audio mode shifts the math, so decide which mode you expect to use before you compare numbers.
Be honest about the sound claim
Noise-canceling or spatial-audio branding from a manufacturer does not measure how these will sound on your head. Once your connection needs are settled, move on to fit, seller terms and the actual offer.
What this page can’t tell you
- Measured ANC performance and call quality are not ranked here.
- Different manufacturer test conditions stand behind the two 30-hour claims.
