MINOR · GEMINI · QUESTION 24

Gemini changed its list 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-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.

  2. Bose QuietComfort Ultra
  3. Sony WH-1000XM4
  4. Sennheiser Momentum 4 Wireless
  5. Sony WH-1000XM5
  6. Bose QuietComfort

For long-haul flights, the criteria for a great headphone change slightly compared to everyday use. Comfort (for 8+ hours of wear), battery life, portability (folding designs), and low-frequency Active Noise Cancellation (ANC) to block engine drone become the absolute most important features.

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

1. Bose QuietComfort Ultra

  • •The absolute best for travel
  • •Battery Life: 24 hours
  • •Why it ranks #1: Bose has long been the king of the airplane cabin, and the Ultras are their masterpiece. They offer arguably the best ANC on the market for blocking out engine roar and crying babies. More importantly, they feature best-in-class clamping force and earcup depth, meaning you can wear them for 14 hours straight without getting a headache. Crucially for travelers, they fold up on hinges into a compact travel case.

2. Sony WH-1000XM4

  • •The best value & practicality for flyers
  • •Battery Life: 30 hours
  • •Why it ranks #2: You might wonder why the older XM4 beats the newer XM5 on this list. It comes down to travel design. The XM4s fold up into a much smaller footprint than the XM5s, taking up significantly less space in your carry-on. They also offer world-class ANC, excellent sound quality, and multipoint Bluetooth pairing. Because they are a previous generation, you can often find them at a significant discount.

3. Sennheiser Momentum 4 Wireless

  • •The battery life & sound quality champion
  • •Battery Life: 60 hours
  • •Why it ranks #3: If you are flying from New York to Singapore and back, these are the headphones for you. The 60-hour battery life (with ANC turned on) completely obliterates the competition; you won't even need to pack the charger in your personal item. Furthermore, they offer the best pure audio quality on this list. The ANC is excellent, though slightly just below Bose and Sony. (Note: They fold flat, but do not collapse inward).

4. Sony WH-1000XM5

  • •The supreme tech powerhouse
  • •Battery Life: 30 hours
  • •Why it ranks #4: If you don't mind sacrificing a bit of bag space, the XM5s are phenomenal. They use an auto-optimizing ANC system that constantly adjusts to your environment, making them incredibly effective at silencing sudden cabin noises. They are incredibly lightweight and have the best microphones on the market if you need to take a business call on a layover. They only drop to #4 because the case is quite large and bulky for travel since the headphones do not fold at the hinges.

5. Bose QuietComfort (2023 Edition)

  • •The classic, no-nonsense travel companion
  • •Battery Life: 24 hours
  • •Why it ranks #5: The direct successor to the legendary QC45, the standard Bose QuietComfort is a staple of frequent flyers. They are incredibly lightweight, fold up completely, and feature tactile, physical buttons (which are much easier to use than touch-controls when you are half-asleep in a dark airplane cabin). They don't have the premium build materials of the Ultras, but they are cheaper, lighter, and just as comfortable.

A quick summary to help you choose:

  • •Choose Bose QC Ultra if you want the absolute best comfort and noise cancellation money can buy.
  • •Choose Sony WH-1000XM4 if you want the best balance of top-tier ANC and a compact, foldable travel footprint.
  • •Choose Sennheiser Momentum 4 if you are taking ultra-long flights and refuse to worry about battery life.

Travel Tip: All of these headphones come with an included 3.5mm aux cable so you can plug into the in-flight entertainment system. However, consider buying a cheap Bluetooth Airline Transmitter (like the Twelve South AirFly) so you can connect to the seatback screen wirelessly.
