Main trade-off
Sony WH-1000XM5
Starting USB charging turns XM5 off and prevents powered playback. It cannot provide the same documented USB listening-and-charging desk route.
Head-to-head
Sony WH-1000XM5 vs Bowers & Wilkins Px7 S3: Px7 plays and charges over USB, Sony works unpowered
The short answer
Choose Px7 S3 if a low-battery day usually happens at a computer with a usable USB audio port. It can listen and charge there. Choose WH-1000XM5 if the fallback you need is a headphone jack with no battery power. Sony’s analog mode works passively without ANC. Px7’s analog connection needs power and occupies USB-C. Both lose Bluetooth during their documented wired listening routes.
Before you choose
The reasoning and the trade-offs
The best low-battery choice changes between the desk and the aircraft seat
If you forget to charge before working at a USB-equipped laptop, Px7 can keep playing while the same cable supplies power. Sony’s XM5 shuts down when charging starts. On a flight with only an analog headphone output, the result reverses: Sony plays passively after its battery empties, while Px7 still needs charge. This is why a general battery winner would be misleading. Decide where a forgotten charge is most likely to interrupt you. A compatible source and cable are required, and passive Sony playback has no ANC.
What this is based on
Two distinct failure conditions using the documented power and input paths. No assumption that an aircraft offers USB audio or usable charging power.
Main trade-off
Bowers & Wilkins Px7 S3
The analog cable still needs battery power and uses the charging socket. Its USB convenience at a desk does not transfer to an analog aircraft seat.

Bowers & Wilkins Px7 S3
- Choose it for
- You need to continue a USB computer listening session while the same cable charges the battery.

About this comparison
Compare Sony XM5 and Bowers Px7 S3 for a low-battery desk, wired travel and phone interruptions. See when USB charging helps and when the analog cable blocks it.
The still-sold XM5 and Px7 S3 both suit a buyer who wants an ANC pair for work and travel. Neither folds inward. Their opposite responses to low battery at a computer and at an analog source create a meaningful decision.

What matters in practice
The differences that matter

How we reached this conclusion
Two distinct failure conditions using the documented power and input paths. No assumption that an aircraft offers USB audio or usable charging power.
Two sockets do not automatically mean two connections can work together
Sony has separate analog and USB-C sockets, which may look more flexible than Px7’s shared socket. Its instructions still prohibit powered playback while charging. Px7 makes the physical conflict obvious because the analog lead occupies USB-C. Neither should be bought for a promised analog-plus-charging setup based on the connector diagram alone. At a desk, switching Px7 to its documented digital USB route is the useful workaround. For Sony, charge before the session or use its unpowered analog fallback without ANC.
How we reached this conclusion
Physical connectors cross-checked against operating restrictions rather than treated as evidence of simultaneous functionality.
USB convenience can conflict with staying available to your family
Someone using a laptop for work may want a phone call from school to interrupt the audio. Px7 does that in its Bluetooth multipoint workflow, but plugging in USB disconnects the wireless devices. Sony analog also removes Bluetooth. If that interruption is important, choose a wireless session or keep a visible or independent phone alert instead of relying on the headphones. Px7’s USB benefit remains valuable for focused listening, but it should not be mistaken for a simultaneous wired-and-wireless call mixer.
How we reached this conclusion
Documented Bluetooth handoff scope and wired exclusions crossed with an important incoming-call requirement.

Which headphones work with the way you listen?
Start with the way you listen. USB charging is not the same as USB audio, and some headphones need power even with a cable. These choices are examples until you apply yours.

Battery figures are manufacturer claims for the stated mode, not measured travel time. Volume, codec, calls and battery age change runtime. Closed earcups can still leak sound. Weight alone does not predict comfort. USB audio needs a compatible source and cable. This check does not assess sound quality, microphone quality or amplifier power.

Meaningful differences
What changes the fit
| What changes | Sony WH-1000XM5 | Bowers & Wilkins Px7 S3 | Why it matters |
|---|---|---|---|
| Low-battery computer session | Starting USB charging turns the headphone off | USB audio and charging from a capable computer | Px7 avoids a listening break when the computer and cable support that route. |
| Empty-battery analog | Playback without power or ANC | Battery charge and power-on required | The advantage reverses when the source only provides an analog output. |
| Charging port during analog | Separate USB-C and analog sockets, powered use during charging prohibited | Analog lead occupies USB-C | Socket count alone does not prove simultaneous charging and listening. |
| Bluetooth while wired | Unavailable with supplied analog cable | Disconnected by analog or USB audio | A parent awaiting a call should not assume wired listening retains multipoint handoff. |
| Bluetooth volume interface | Touch sensor | Physical volume buttons | Pick the interface you prefer. Both require source controls for analog volume. |
| Storage mechanism | Turns flat, no inward fold | Turns flat, no inward fold | Neither solves a strict inward-fold requirement. Check the case against the available bag space. |
What you give up
Every choice has a cost
If you choose Sony WH-1000XM5
- The frame turns flat but does not fold inward. An analog call uses the source microphone, and Bluetooth is disabled in that mode.
If you choose Bowers & Wilkins Px7 S3
- USB listening disconnects Bluetooth. Keep a separate way to notice important phone calls during the wired session.
Recommendation switch
The decision flips if...
A compatible computer is the usual place I recover from a missed charge
Choose Bowers & Wilkins Px7 S3. Px7’s USB listening-and-charging path addresses that interruption.
I need a battery-free analog travel fallback
Choose Sony WH-1000XM5. XM5 provides passive playback with no ANC.
An inward-folding frame is essential
Choose neither. Both turn flat without an inward fold.
What matters in practice
Before you choose
You want a pair that survives forgotten charging at home and on a flight. Px7 can listen and charge from a capable USB computer. XM5 instead offers passive analog playback, while connecting its charger stops powered operation.
What this comparison cannot tell you
- No matched sound, ANC, comfort or call test establishes a winner.
- Neither connector count nor a USB-C label establishes an undocumented operating mode.
