Noise-Cancelling Headphones for Flights
Sound quality is not something we can assess. Battery life with noise cancelling on is published, and on a plane it is the number that decides whether you carry a charger.
We have not tested this gear. Every figure here is compiled from published manufacturer specifications and published airline policies, and the arithmetic is public so you can check it. This page contains affiliate links — see the affiliate disclosure.
Both cover a single long-haul flight on one charge. The published difference is 30 h against 50 h with noise cancelling on, and 251 g against 295 g. Buy the Sony for weight, the Soundcore for endurance and a published price. Neither publishes a warranty term.

What we can compare, and what we cannot
We have not listened to either of these. Sound quality, how effectively each one cancels the specific low-frequency drone of a cabin, and how the pads feel after eight hours are the three things people actually buy headphones on, and we have no basis for an opinion on any of them.
What is published, and what genuinely decides this purchase for a traveler, is battery life with noise cancelling engaged and weight on your head. Those are the two figures below, and they point in opposite directions.
Battery life against real flight lengths
A battery figure only means something against a trip. Here is what each published rating actually covers:
| Route | Approximate flight time | Sony, 30 h | Soundcore, 50 h |
|---|---|---|---|
| New York to Los Angeles | ~6 h | Five flights on one charge | Eight flights on one charge |
| New York to London | ~7 h | Four flights | Seven flights |
| Los Angeles to Tokyo | ~12 h | Two flights | Four flights |
| Los Angeles to Sydney | ~15 h | Two flights | Three flights |
| A two-week trip, four legs plus airport time | ~35 h | One charge mid-trip | No charging needed |
Every flight on earth fits inside 30 hours, so both headphones clear the single-flight test comfortably. The difference only appears across a whole trip — and it is the difference between remembering a USB-C cable and not.
Worth noting: if you carry a power bank anyway, and most people should, the endurance gap shrinks to almost nothing. A published 36 Wh bank recharges either set several times over.
44 grams, and whether it matters
251 g against 295 g is a 17% difference, and it sits on your head rather than in your bag. Over a twelve-hour flight that is a real consideration, and it is the strongest argument for the Sony.
Against your baggage allowance, though, neither is significant: even the heavier set is 0.65 lb, under three percent of Hawaiian’s published 25 lb carry-on cap. This is a comfort decision rather than an allowance one.
How they pack
Soundcore publishes that the Q45’s cups pivot and retract; Sony’s case does not fold flat. In a 20 L personal item that is a genuine difference — a rigid headphone case is one of the most awkwardly-shaped objects most people carry, and it competes directly with a laptop for the flat space against the back panel.
The practical answer either way: the headphones go on your neck or in the seat pocket, not in the bag, and the case travels empty. That is also the only way to guarantee they are not inside a bag that gets gate-checked.
Neither publishes a warranty term
This is the finding that surprised us, and it is a category-wide problem rather than a criticism of either brand. Both companies publish detailed acoustic and battery specifications and neither states a warranty term in the specification sheets we compiled.
On a site that weights warranty terms at 20%, that means both of these score on fewer axes than a suitcase does. Consumer electronics are simply not sold the way luggage is — a ten-year term is normal on a carry-on and unheard of on headphones. We would rather say so than pretend the comparison is complete.
The verdict
- You fly long-haul and value comfort over everything → Sony WH-1000XM5. 44 g lighter, and 30 h covers any single flight.
- You take multi-leg trips and forget chargers → Soundcore Space Q45. 50 h published, and it packs flatter.
- You want a published price to judge value against → Soundcore, at $149. Sony publishes none.
- Sound quality is your first criterion → neither of these entries will help you, and we are not going to pretend otherwise. A site that listens to headphones is the right source for that question.
Every pick, with the working
Each entry below shows the published inputs, the four axis scores they produce, and what you give up. The order is the computed order, not a commercial one.
1 · Long-haul flights where you would rather not carry a charger for the headphones
Sony WH-1000XM5 Noise-Cancelling Headphones
Skip this one. Skip it if a charger is the thing you forget. The Sony is 44 g lighter and publishes 30 hours with noise cancelling on, which covers any single flight — but the Soundcore publishes 50, and on a three-leg trip that is the difference between packing a cable and not. Neither maker publishes a warranty term in the specification sheets we compiled.
251 g and a published 30 hours with noise cancelling on — enough for a transatlantic round trip on one charge, which is the only battery figure that matters on a plane.

What it does well
- 251 g published — the lightest over-ear in this comparison by 44 g
- Up to 30 h with noise cancelling on covers any single flight on earth
- 3 minutes of charge yields 3 hours of playback with a USB-PD adapter
What you give up
- Sony publishes no warranty term in the specification sheet we compiled
- The case does not fold flat, so it takes real volume in a personal item
- No manufacturer-published price
The arithmetic behind the score
- Value not scored — No manufacturer-published price, so this axis is not scored.
- Airline-fit breadth not scored — No published dimensions to check against carrier limits.
- Carry efficiency not scored — No published capacity, so weight per liter cannot be computed.
- Warranty & support 0.0/10 — no published term (0 of 6); no published repair route (+0); airline damage not covered (+0)
Weights and breakpoints are published on how we rank. Where an input is not published, that axis is dropped and the remaining weights are re-normalized.

2 · Multi-leg trips where charging the headphones is an annoyance
Soundcore Space Q45 Noise-Cancelling Headphones
A published 50 hours with noise cancelling on is 20 more than the Sony, which is the difference between charging once a trip and not thinking about it at all.

What it does well

- 295 g is 44 g heavier than the Sony
- No published warranty term
- 40 mm drivers and Bluetooth 5.3 are specs, not a sound-quality claim — we have not listened to either
