The catch
Sony WH-1000XM4C
Bluetooth is disabled by the supplied analog cable, which relies on the source phone microphone for speech. With LDAC the 27-hour ANC claim falls to 20.
Side by side
Sony WH-1000XM4C vs Bose Ultra 2 for Flights and a Shared TV: Bose shares compatible TV audio, Sony works unpowered
Quick verdict
If you absolutely need to keep listening over analog after the headphone battery dies, WH-1000XM4C is the one. Bose QuietComfort Ultra 2 is for people who own compatible Bose Smart equipment for SimpleSync shared listening, or who want its documented USB-audio input. Both fold inward. Bose’s analog route still needs power, so weigh that trade-off before assuming it is the safer travel choice.
Before you buy
Why, and what it costs you
Separate TV volumes call for an audio path that keeps both listeners connected
If one person wants louder dialogue and another wants a quiet room, a Bluetooth logo does not say whether the TV speaker stays active. Through SimpleSync with compatible Bose Smart equipment, Bose documents independent headphone and speaker volume. That is a concrete reason to choose it when your room already has the right hardware. Sony may work through a TV or transmitter, but simultaneous speaker output and delay depend on that equipment. We have not verified a universal Sony setup or a hearing benefit.
Where this comes from
A documented ecosystem connection set against two listeners who want different volumes. No universal TV compatibility or medical claim is made.
The catch
Bose QuietComfort Ultra Headphones (2nd Gen)
Sony’s battery-free analog fallback is not something it offers. SimpleSync depends on compatible Bose equipment and is no promise for every TV.
Sony WH-1000XM4C
- Why pick it
- You need an analog fallback that still works with the headphone powered off. ANC isn’t available then.
- A folding travel pair is what you want, and the Bose-specific shared-TV connection isn’t something you need.
- The catch
- Bluetooth is disabled by the supplied analog cable, which relies on the source phone microphone for speech. With LDAC the 27-hour ANC claim falls to 20.
Bose QuietComfort Ultra Headphones (2nd Gen)
- Why pick it
- You already own compatible Bose Smart equipment and want headphones and speakers at separate volumes through SimpleSync.
- Documented USB audio, or powered analog during charging, is what you’re after. Analog still needs power, and the second setup takes two cables.
- The catch
- Sony’s battery-free analog fallback is not something it offers. SimpleSync depends on compatible Bose equipment and is no promise for every TV.

What this page compares
Sony XM4C and Bose Ultra 2 for travel and a shared TV. Learn which one plays through a cable with no battery, and when Bose’s independent TV volume calls for extra equipment.
These are folding ANC headphones for everyday travel. Bose adds a documented shared-TV workflow and USB audio. Those extras count only if they suit the buyer’s equipment and power routine.

The cable in your flight bag may still call for a second cable
Suppose a flight follows a workday and you missed a charge. Sony can play from the seat’s headphone output with its power off, while Bose requires power for analog audio. The Bose manual permits USB charging alongside that analog connection, but then you also need an available USB power source and lead. When the only dependable seat connection is analog, Sony is the simpler fallback. Powered ANC is unavailable on an empty Sony, and either pair may need an aircraft adapter.
How we worked this out
This covers failure-state and simultaneous-connection requirements and does not assume power is available on the aircraft.
Whichever feature you leave on changes the endurance to plan around
If you buy Bose for Immersive Audio, plan from its 23-hour claim and not its 30-hour maximum. If you choose Sony for LDAC plus ANC, use 20 hours and not 27. These figures do not establish a matched winner, because the features and test conditions differ. They do help you avoid a common travel mistake, which is picking a favorite listening mode and planning the journey from a battery claim that belongs to another mode.
How we worked this out
Every manufacturer’s operating condition is kept as stated. It gives no cross-brand performance ratio or measured endurance advantage.
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-1000XM4C | Bose QuietComfort Ultra Headphones (2nd Gen) | In practice |
|---|---|---|---|
| Unpowered analog backup | Music with power off, without ANC | Analog listening requires headphone power | A headphone jack on its own cannot rescue a Bose with an empty battery. |
| Wired digital listening | Analog path documented. USB audio not established by this evidence | USB input, 16-bit at 44.1 or 48 kHz | A verified USB option for a compatible source comes with Bose. Do not assume audio from a charging connector. |
| Shared TV with separate volume | No Bose SimpleSync integration | SimpleSync with compatible Bose Smart speaker or soundbar | A specific ecosystem route exists for Bose. Confirm your exact equipment before you buy. |
| Analog while charging | No claim of powered operation during charging is made here | Separate analog connection can be used with USB power | The powered workaround that Bose documents needs both connections. |
| Mode-specific battery claim | Up to 27 hours AAC/SBC ANC, or 20 LDAC ANC | Up to 30 hours, or 23 with Immersive Audio | Pick the mode you will use before you trust the longest figure. |
| Storage | Inward-folding frame and included case | Inward-folding frame and included case | Folding by itself does not decide this pair. Source compatibility and power draw the stronger line. |
Trade-offs
What each pick costs you
With Sony WH-1000XM4C
- Run its ANC optimizer again when wearing conditions change, such as taking off glasses. The US box has no charging cable.
With Bose QuietComfort Ultra Headphones (2nd Gen)
- To charge while using an analog seat or TV output, keep USB power on hand next to the analog lead. Immersive Audio cuts the published 30-hour claim to 23 hours.
Change of plan
When the answer changes
The travel fallback has to work without any battery power
Go with Sony WH-1000XM4C. That requirement is met by the passive analog route on Sony, without ANC.
You own compatible Bose Smart equipment for shared TV or need documented USB input
Go with Bose QuietComfort Ultra Headphones (2nd Gen). Those verified connection routes make Bose’s extra setup and powered-analog requirement worth it.
Decision guide
Before you buy
A single pair has to serve on flights and in front of the television, without forcing everyone else to live with your volume. Sony supplies a battery-free travel backup. Bose can share TV sound at its own volume via compatible Bose equipment, yet it needs power even over analog.
What this page can’t tell you
- We claim no comparative result on ANC, hearing outcome, TV delay or microphone isolation.
- No ambient or transparency mode can promise that you will hear a child, an alarm or an announcement.
