MINOR · GEMINI · QUESTION 24

Gemini went back to its earlier list for a request for a ranked top 5 of noise-cancelling headphones.

Why it’s minor

The change lasted one day before the model went back.

The full answers

Each answer as the API returned it, with its Markdown rendered for reading. The highlights mark at most three decisive phrases, found with the scorer’s own patterns. Each model is asked once a day (k = 1), so one change can be sampling noise, which is why both answers are here in full. How scoring works.

Picks read from the answer, in order
  1. Sony WH-1000XM4
  2. Bose QuietComfort Ultra
  3. Sennheiser Momentum 4 Wireless
  4. Sony WH-1000XM5
  5. Bose QuietComfort

Here is the ranked top 5 list of noise-cancelling headphones specifically chosen for long-haul flights.

For a 10+ hour flight, criteria like comfort (clamping force/weight), battery life, the ability to fold into a compact travel case, and low-frequency noise cancellation (for engine drone) are just as important as sound quality.

1. Sony WH-1000XM4

  • •The Best Overall for Travel
  • •Why it ranks #1: Even though Sony released the newer XM5, frequent flyers largely prefer the XM4. Why? Because the XM4 features hinges that allow them to fold down into a very compact, hard travel case that easily fits into a packed personal item. They offer top-tier noise cancellation that completely erases airplane engine drone, they are incredibly lightweight, and they have a 30-hour battery life.
  • •Battery: 30 hours
  • •Folds for travel: Yes

2. Bose QuietComfort Ultra

  • •The Best for Comfort & Pure Noise Cancellation
  • •Why it ranks #2: Bose has always been the king of the airplane cabin, and the Ultras are their newest flagship. They have arguably the best Active Noise Cancellation (ANC) on the market right now. More importantly for a long-haul flight, they are supremely comfortable, with soft earcups and very low clamping force, meaning you can wear them for 15 hours without getting a headache.
  • •Battery: 24 hours
  • •Folds for travel: Yes

3. Sennheiser Momentum 4 Wireless

  • •The Best for Battery Life & Sound Quality
  • •Why it ranks #3: If you are flying from New York to Sydney, this is the headphone you want. The Momentum 4 boasts an absolutely insane 60-hour battery life with ANC turned on. You can do the flight, the entire vacation, and the return flight without ever reaching for a charger. They also offer audiophile-grade sound quality. The only downside is that they fold flat, but don't fold inward, meaning the travel case is a bit larger.
  • •Battery: 60 hours
  • •Folds for travel: Folds flat (but not inward)

4. Sony WH-1000XM5

  • •The Best for Modern Tech & Smart Features
  • •Why it ranks #4: Sony's newest flagship headphones are spectacular. The ANC is slightly more refined than the XM4, they sound incredible, and they are very lightweight. The only reason they sit at #4 for flights specifically is their design: they do not fold on hinges. Because they only fold flat, their travel case is unusually large and takes up a lot of premium space in a backpack.
  • •Battery: 30 hours
  • •Folds for travel: Folds flat (but not inward)

5. Bose QuietComfort (2023 Edition)

  • •The Best Lightweight/High-Value Option
  • •Why it ranks #5: Replacing the legendary QC45s, the standard Bose QuietComfort headphones are the quintessential travel headphone. They are the lightest headphones on this list, making them feel like a cloud on your head. They fold up into a tiny profile, block out engine noise flawlessly, and are generally priced lower than the other flagship models on this list.
  • •Battery: 24 hours
  • •Folds for travel: Yes

Note for flyers: All five of these headphones come with a 3.5mm audio cable in the case, which you will need if you want to plug into the seatback in-flight entertainment system.

Picks read from the answer, in order
  1. Active Noise Cancellation
  2. Bose QuietComfort Ultra
  3. Sony WH-1000XM5
  4. Sennheiser Momentum 4 Wireless
  5. Sony WH-1000XM4
  6. Apple AirPods Max

Here is the ranked top 5 list of the best noise-cancelling headphones specifically suited for long-haul flights.

For 8+ hour flights, the ranking criteria heavily weigh Active Noise Cancellation (ANC) for engine drone, long-term comfort (clamping force and weight), battery life, and travel portability.

1. Bose QuietComfort Ultra

  • •The Best Overall for Air Travel
  • •Why it ranks #1: Bose is the undisputed king of blocking out low-frequency airplane cabin noise. The QC Ultras are incredibly lightweight with a gentle clamping force, meaning you can wear them for a 14-hour flight without getting a headache. Unlike their closest competitor (the Sony XM5), they fold up compactly into a smaller travel case, which is a massive advantage for carry-on packing.
  • •Battery Life: 24 hours.

2. Sony WH-1000XM5

  • •The Runner-Up & Best All-Rounder
  • •Why it ranks #2: Sony’s flagship headphones offer phenomenal, adaptive ANC that automatically adjusts to the changing pressure and noise of an airplane cabin. They sound slightly better than the Bose and feature excellent fast-charging (3 minutes plugged in gets you 3 hours of playback). They only drop to #2 because they do not fold on hinges; they only lay flat, meaning their travel case takes up noticeably more room in a backpack.
  • •Battery Life: 30 hours.

3. Sennheiser Momentum 4 Wireless

  • •The Battery Life Champion
  • •Why it ranks #3: If you are flying from New York to Singapore and back, you won't even need to pack a charger. The Momentum 4 boasts an unbelievable 60-hour battery life with ANC turned on. Combine that with Sennheiser’s superior, audiophile-grade sound quality and plush ear pads, and they are a dream for frequent, long-haul flyers. The ANC is excellent, though just a hair less powerful than Bose and Sony.
  • •Battery Life: 60 hours.

4. Sony WH-1000XM4

  • •The Best Value / Practical Traveler's Choice
  • •Why it ranks #4: Despite being the older generation to the XM5s, many frequent flyers still prefer the XM4s. Why? Because they fold up into a tiny ball. They take up very little space in your personal item, still feature elite-level noise cancellation, are incredibly comfortable, and because they are a previous generation, you can often find them heavily discounted.
  • •Battery Life: 30 hours.

5. Apple AirPods Max

  • •The Best for the Apple Ecosystem (with caveats)
  • •Why it ranks #5: If you are an iPhone/iPad/Mac user, the seamless switching and spatial audio while watching movies on your iPad is unmatched. The ANC and transparency modes are arguably the best on this list. However, they rank #5 for long-haul travel due to two major flaws: They are very heavy (mostly metal) and can cause neck/crown fatigue after 5 or 6 hours, and the included "case" offers zero protection for being stuffed into a tightly packed carry-on bag.
  • •Battery Life: 20 hours.

Pro Travel Tip: Whichever pair you choose, if you want to watch the seatback in-flight entertainment (movies) wirelessly, consider buying a Bluetooth transmitter like the Twelve South AirFly. It plugs into the plane's headphone jack and transmits the audio via Bluetooth to your wireless headphones.
