MINOR · GEMINI · QUESTION 24

Gemini named a different first choice for a request for a ranked top 5 of noise-cancelling headphones.

Why it’s minor

Which products a model recommends is read out of its answer by the least reliable part of our scorer, so compare the two answers before reading much into this.

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.

Best noise-cancelling headphones for long-haul flights — give me a ranked top 5 with brand and model.

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

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

For long-haul travel, rankings prioritize Active Noise Cancellation (to block jet engine drone), long-term comfort (for 8+ hour wear), battery life, and packability.

1. Bose QuietComfort Ultra

  • •Why it ranks #1 for flights: Bose is the undisputed king of blocking out low-frequency airplane engine noise. The Ultras are exceptionally light, have deep earcups that don’t press against your ears, and crucially for travel, they fold up compactly into their case. The new "Immersive Audio" feature also makes watching movies on your tablet feel like a home theater experience.
  • •Battery Life: Up to 24 hours.

2. Sony WH-1000XM4

  • •Why it ranks #2 (and beats its newer sibling): While Sony has released the newer XM5, frequent flyers still largely prefer the XM4. Why? It folds. The XM4 collapses into a much smaller travel case than the newer model. It still boasts world-class noise cancellation, phenomenal sound quality, and physical touches that make it a legendary travel companion.
  • •Battery Life: Up to 30 hours.

3. Sennheiser Momentum 4 Wireless

  • •Why it ranks #3 for flights: Battery anxiety is real on long-haul flights, and Sennheiser eliminates it completely. These boast an absurd 60 hours of battery life with ANC turned on. You could fly from New York to Singapore and back, and still have battery left over. The sound quality is arguably the best on this list, and the earcups are very plush.
  • •Battery Life: Up to 60 hours.

4. Sony WH-1000XM5

  • •Why it ranks #4 for flights: The XM5 actually has slightly better noise cancellation and microphone quality than the XM4. The headband is also completely redesigned to be ultra-light, preventing the "crown ache" some get after 10 hours of wear. The only reason it sits at #4 for travel is that it does not fold; the travel case is quite large and takes up significant space in a personal item or backpack.
  • •Battery Life: Up to 30 hours.

5. Bose QuietComfort (2023 Edition)

  • •Why it ranks #5 for flights: This is the direct replacement for the legendary Bose QC45. It lacks the premium materials of the "Ultra" (rank #1), but it keeps the classic, highly packable folding design and top-tier noise cancellation. It also utilizes tactile, physical buttons rather than touch controls, which many travelers prefer when trying to adjust volume or pause in a dark airplane cabin.
  • •Battery Life: Up to 24 hours.

A Quick Note on Apple AirPods Max:
While the AirPods Max have incredible ANC, they are left off this specific travel list for three reasons: they are very heavy (which causes neck fatigue on 10-hour flights), the case offers zero protection in a backpack, and they do not come with an audio cable, meaning you cannot plug them into the seatback in-flight entertainment system without buying a separate $35 proprietary cable.

Traveler Pro-Tip: Whichever pair you buy, check the box before you leave for the airport. Most of the headphones above come with a 3.5mm audio cable and an airplane adapter, which you will need if you want to watch movies on the seatback screens!

For long-haul flights, the criteria for the "best" headphones change slightly from everyday use. You need top-tier Active Noise Cancellation (ANC) to drown out the low-frequency drone of the engines, supreme comfort so they don’t hurt your ears after 10 hours, long battery life, and portability (including a cable to plug into the in-flight entertainment).

Here is the ranked top 5 based on those specific travel needs:

1. Bose – QuietComfort Ultra

  • •The Verdict: The absolute best for long-haul travel.
  • •Why for flights: Bose practically invented aviation headsets, and it shows. The ANC on the QC Ultras is arguably the best on the market at eliminating airplane engine rumble. More importantly, they have a very low clamping force, making them the most comfortable headphones for a 15-hour flight. Unlike their main rival (the Sony XM5), they fold up compactly into a small travel case.
  • •Battery: 24 hours (with ANC on).
  • •Wired for In-Flight TV: Yes (cable included).

2. Sony – WH-1000XM5

  • •The Verdict: The best all-rounder with the smartest tech.
  • •Why for flights: The ANC is neck-and-neck with Bose, and they feature an "Auto NC Optimizer" that automatically adjusts the noise cancellation based on the atmospheric pressure in the airplane cabin. The battery life is stellar, and they charge incredibly fast (3 hours of playback from a 3-minute charge). The only reason they are #2 is that they do not fold on hinges, meaning their travel case takes up noticeably more room in your personal item.
  • •Battery: 30 hours (with ANC on).
  • •Wired for In-Flight TV: Yes (cable included).

3. Sennheiser – Momentum 4 Wireless

  • •The Verdict: The battery life king.
  • •Why for flights: If you are flying from New York to Singapore, having a layover, and flying somewhere else, these are for you. They boast an astonishing 60-hour battery life with ANC turned on. You can leave your charger packed away for the entire trip. While the ANC isn't quite as absolute as Bose or Sony, it is still excellent, and the sound quality for music is noticeably superior to both of them.
  • •Battery: 60 hours (with ANC on).
  • •Wired for In-Flight TV: Yes (cable and airplane two-prong adapter included).

4. Sony – WH-1000XM4

  • •The Verdict: The frequent-flyer favorite that refuses to step down.
  • •Why for flights: Even though these are the older generation (replaced by the XM5 at the #2 spot), seasoned business travelers still buy these specifically for flights. Why? Because they fold up. You get 95% of the ANC and sound quality of the newer XM5, but in a much more travel-friendly, compact form factor. They also frequently go on sale now, making them a great value.
  • •Battery: 30 hours (with ANC on).
  • •Wired for In-Flight TV: Yes (cable and airplane two-prong adapter included).

5. Bowers & Wilkins – Px7 S2e

  • •The Verdict: The premium luxury upgrade.
  • •Why for flights: If you find the plastic builds of Sony and Bose a bit cheap, B&W offers aluminum arms, memory foam, and premium fabrics. They look and feel like first-class travel accessories. The clamping force is well-balanced for long wear, the ANC is highly effective at blocking cabin noise, and the high-fidelity sound profile is incredibly rich.
  • •Battery: 30 hours (with ANC on).
  • •Wired for In-Flight TV: Yes (USB-C to 3.5mm cable included).

(Note: The Apple AirPods Max are noticeably absent from this list. While they have incredible ANC, they are very heavy for 10+ hour wear, have a battery life of only 20 hours, feature a highly protective-lacking travel case, and do not come with a cable to plug into the airplane TV—you have to buy a $35 proprietary cable separately).
