The catch
Sony WH-1000XM6
Calls with the supplied analog cable go through the source’s microphone. The USB charging socket on it is no evidence of a USB audio path.
Side by side
Sony WH-1000XM6 vs Bowers & Wilkins Px7 S3 Compared: Px7 USB drops Bluetooth, Sony works unpowered
Quick verdict
WH-1000XM6 is the pick for a folding travel frame, lower listed weight and analog playback on an empty battery. Px7 S3 is the pick for documented USB audio and charging from a capable computer, or for physical Bluetooth volume buttons. On Px7, USB mode disconnects Bluetooth, and the analog cable needs power while it occupies the charging socket. Sony also disables Bluetooth when its analog cable is in use. Neither passive listening nor a cable automatically keeps every wireless feature.
Before you buy
Why, and what it costs you
The USB feature you buy for work may cost you the phone handoff you also wanted
Px7’s USB route works well with a laptop that provides both audio and power. When it is connected, the headphone drops Bluetooth. So a parent waiting for a school call to cut into the music needs a separate alert or has to go back to wireless. Sony’s analog connection carries the same Bluetooth restriction, which means picking it does not fix the wired handoff problem. What you decide is whether the documented one-cable desk route is worth that trade-off to you. Neither pair is verified here as a mixer for wired and wireless audio at the same time.
Where this comes from
This pairs connection-mode exclusions with an important phone interruption. It does not claim that every call is missed or that wireless handoff guarantees delivery.
The catch
Bowers & Wilkins Px7 S3
Powered analog takes up the USB-C port, and you set analog volume at the source. The 300 g frame does not fold inward.
Sony WH-1000XM6
- Why pick it
- Your travel bag is crowded, and you need a folding pair plus battery-free analog playback. That fallback comes without ANC.
- Documented use while charging matters to you. Sony stops charging at roughly 80% during use and notes that electrical noise is possible.
- The catch
- Calls with the supplied analog cable go through the source’s microphone. The USB charging socket on it is no evidence of a USB audio path.
Bowers & Wilkins Px7 S3
- Why pick it
- You want USB sound and charging through a single capable computer port, and you have a separate plan for phone alerts.
- Physical volume buttons are your preference during Bluetooth use. Those controls stop working through the supplied analog interface.
- The catch
- Powered analog takes up the USB-C port, and you set analog volume at the source. The 300 g frame does not fold inward.

What this page compares
Sony XM6 against Bowers Px7 S3 for travel and a USB desk. See how they handle battery-free analog, phone interruptions, charging during use and controls that change with the cable.
Both premium ANC headphones are after the same travel-and-work budget. USB input and folding make a useful first comparison, yet a real decision also depends on the power state, phone handoff and control restrictions of each route.

A lighter frame and a no-power fallback solve different travel problems
Sony’s listed 254 g sits 46 g under Bowers’s 300 g, and its inward fold can suit a busy carry-on. Those points are about carrying and storage. Passive analog covers a separate failure, which is getting audio at your seat once the battery has died. Px7’s supplied analog lead still needs power and uses USB-C, so packing its charging lead does not automatically let you add power during that analog session. When an analog output is your only dependable source, Sony is the stronger documented fallback. You still need the right adapter, and ANC is gone when Sony has no power.
How we worked this out
300 minus 254 equals 46 g, with cases and cables left out. This keeps storage, carried mass and power-failure consequences apart and does no comfort or case-volume calculation.
Buttons bought for easier handling can let you down at the hi-fi socket
Someone who dislikes touch gestures may like the physical buttons on Bowers. Over its analog cable, volume and play/pause no longer work on the headphone. Sony also depends on the source controls for analog volume. If you sit far from a hi-fi system or often use an aircraft socket, make sure the source remote or seat controls are easy to reach. Choose Px7’s buttons for your Bluetooth routine and not for an analog remote it never promised. Liking one control style does not establish an accessibility or medical benefit.
How we worked this out
This crosses control behavior with a source that is physically out of reach. It makes no unsupported claim about gloves or any particular impairment.
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.

Spec by spec
Where they really differ
| Spec | Sony WH-1000XM6 | Bowers & Wilkins Px7 S3 | In practice |
|---|---|---|---|
| Packing and listed mass | Inward fold and approximately 254 g | No inward fold and 300 g | Before the case and cables, Sony is listed 46 g lighter. You still need to check the fit for comfort. |
| Analog with no battery | Works without ANC | Requires enough charge and power-on | A missed charge still leaves Sony with a simple analog fallback. |
| USB desk route | Charging and use documented, USB audio undocumented | USB audio and charging from a capable computer | On these headphones, USB-C is documented for different jobs. |
| Important phone call during wired listening | Analog disables Bluetooth | Analog and USB disconnect Bluetooth | Multipoint handoff should not be assumed to continue once the wire is connected. |
| Physical volume control | Touch sensor for Bluetooth, source control for analog | Buttons for Bluetooth, inactive for analog | The tactile edge of Bowers holds in one mode and not on every connection. |
| Long analog session | Passive fallback and separate charging connector | Powered analog occupies USB-C | At the same time, Px7’s ordinary charger cannot occupy that same socket. No splitter has been validated. |
Trade-offs
What each pick costs you
With Sony WH-1000XM6
- At a listed 254 g, it is 46 g under Px7, but lower mass says nothing about lower clamping pressure or comfort with glasses.
With Bowers & Wilkins Px7 S3
- Playback of up to 24-bit 96 kHz over USB describes the input. It proves no audible advantage, and using USB disconnects Bluetooth.
Change of plan
When the answer changes
Priority goes to folding travel storage and an analog fallback that needs no power
Go with Sony WH-1000XM6. Sony is the one with the documented combination.
Most important is a one-cable USB route for computer listening
Go with Bowers & Wilkins Px7 S3. Px7 carries audio and charging, and Bluetooth is disconnected.
Decision guide
Before you buy
A tidy one-cable desk and a dependable travel fallback are the goal. Px7 S3 gives you USB audio and charging together, but wired mode drops the phone connection and analog still needs power. XM6 folds and keeps a passive analog fallback.
