The best foldable noise-canceling headphone is the Sony WH-1000XM6, because it is the only current flagship that folds up — earcups rotate and the headband collapses — producing a compact block rather than a wide slab. The Bose QuietComfort Ultra and Sennheiser MOMENTUM 4 fold flat, which is slim but keeps the headphone’s full width. The Apple AirPods Max does not fold at all: its dimensions are fixed at 168.6 by 83.4 by 187.3 mm.
Three different things
Fold-up, fold-flat, and no fold
Manufacturers use “folding” loosely, and the distinction is the whole point of this page.
Fold-up
The earcups rotate inward and the headband collapses at a hinge, producing a compact three-dimensional block roughly half the footprint of the extended headphone. This is the Sony and the Soundcore. It is the best geometry for a full bag, a packing cube, or a daypack.
Fold-flat
The earcups rotate to lie in the same plane as the headband, producing a thin wide object. This is the Sennheiser, the JBL, and functionally the Bose. It is the best geometry for a laptop compartment and the worst for a cube.
No fold
The headphone is a fixed object and the case is a box the size of it. This is the Apple AirPods Max, whose published dimensions are 168.6 mm by 83.4 mm by 187.3 mm — and whose Smart Case is soft, adds 134.5 g, and leaves the headband exposed.
A rigid case does not compress. A soft one does not protect. The best travel case is a small rigid one, and only three headphones here ship that.
The comparison
Which headphone folds which way
| Model | Fold type | Case | Suits |
|---|---|---|---|
| Sony WH-1000XM6 | Fold-up | Compact hard, magnetic | A full bag, a packing cube |
| Soundcore Space Q45 | Fold-up | Hard shell | A full bag, on a budget |
| Bose QuietComfort Ultra 2nd Gen | Rotates flat | Compact hard | A structured backpack |
| Sennheiser MOMENTUM 4 | Fold-flat | Slim carry case | A laptop compartment |
| JBL Tour One M3 | Fold-flat | Case plus accessories | A laptop bag, with kit |
| Apple AirPods Max (USB-C) | None | Soft Smart Case, headband exposed | A bag with room to spare |
The real arithmetic
How much difference does the fold actually make?
Enough to change what else fits. A fold-up headphone in its case occupies roughly half the volume of an unfolded one, and the practical consequence in a 40-liter personal item that also holds a laptop, a charger, a water bottle and something to read is binary: the headphones go in the bag, or they go round your neck through three terminals.
The Apple case is the clearest illustration. Headphones at 386.2 g plus a case at 134.5 g is 520.7 g of published weight in a fixed-size object that will not compress. The Sony folded, in its case, is a fraction of that footprint. Nothing about sound quality moves the experience of packing as much as that does.
If pack size is the binding constraint on your buying decision, the honest next question is whether you want an over-ear at all — an earbud case goes in a jacket pocket. See earbuds versus over-ear for flying.
Protecting the mechanism
A hinge is the thing that eventually breaks
Worth saying, because it is the counter-argument to everything above. A folding headphone has more moving parts than a fixed one, and headphone hinges are the most common point of eventual mechanical failure in the category. The Apple, which does not fold, has nothing there to fail.
The mitigation is simple and it is the case. Folding a headphone and then putting it loose in a bag applies exactly the loads that stress a hinge; folding it into a rigid case does not. See travel headphone cases for what a good one does, and how to pack headphones for travel for the rest of the technique.
In short
Key takeaways
- Fold-up (Sony, Soundcore) gives a compact block. Fold-flat (Sennheiser, JBL, Bose) gives a thin wide slab. Apple gives neither.
- The right geometry depends on your bag: fold-up for a cube, fold-flat for a laptop compartment.
- A fold-up headphone in its case takes roughly half the volume of one that does not fold.
- Apple AirPods Max is 386.2 g plus a 134.5 g soft case that leaves the headband exposed.
- A hinge is the most common eventual mechanical failure. Always fold into the case, never loose into the bag.

The picks in full
Every pick, in detail
1. Best folding design
Sony WH-1000XM6
The most complete travel headphone on sale: 254 g, 30 rated hours with noise canceling on, and it folds into a case small enough to stop being a decision.
Our editorial score: 9.1 / 10
#ad Live price not shown. How this is funded
Also sold direct by Sony — we earn nothing there, so check both.
The XM6 is the only current flagship that genuinely folds up: the earcups rotate and the headband collapses, producing a compact block rather than a wide slab. The case closes magnetically and is small enough that it stops being a packing decision.
Combined with approximately 254 g, that makes it the least intrusive full-size headphone to travel with, by a clear margin. If the reason you are on this page is that your bag is always full, the search ends here.
The honest caveat: a folding hinge is a mechanism, and mechanisms are what eventually fail on headphones. Use the case rather than the bare fold, and it is a non-issue for years.
What works on a plane
- Folds, which halves the space it takes in a personal item
- 254 g is light for a flagship over-ear, and weight is what you feel at hour four
- LDAC plus LC3 means it is not locked to one phone ecosystem
- 30 rated hours with noise canceling on covers almost any single routing
What does not
- You pay a flagship price for the last increment of noise canceling
- The folding hinge is one more mechanism to eventually wear out
- No airline two-prong adapter in the box

2. Best folding on a budget
Soundcore Space Q45
Fifty rated hours with canceling on, a hard case and a 3.5 mm cable in the box, at a fraction of flagship money. The compromise is in the last 10 percent of quiet, not the first 80.
Our editorial score: 8.2 / 10

It folds, and it ships with a hard-shell case — which for a budget product is genuinely notable, because the case is a real cost and the first thing a manufacturer cuts. On the specific criterion of this page, the cheap headphone matches the flagship.
The plastic build is the reason the case matters more here than anywhere. Approximately 295 g and plainer pads mean hour five is less comfortable, but if you are optimizing for packed volume rather than long-flight comfort this is very hard to beat for the money.
What works on a plane
- Up to 50 rated hours with canceling on, which beats every flagship here
- Hard case and 3.5 mm cable included, so nothing else to buy for a seatback screen
- Five minutes of charge buys four hours, which covers a gate-side mistake
- The cheapest way to get genuinely useful drone reduction on a plane
What does not
- Soundcore's own 98 percent figure is a marketing claim, not a measurement, and the gap to Bose is audible
- 295 g with plainer pad materials, so hour four is less comfortable than the Sennheiser's
- Plastic build will not survive being crushed in an overhead bin the way the metal Apple would

3. Smallest case among the quiet ones
Bose QuietComfort Ultra Headphones (2nd Gen)
The quietest cabin of anything here, and the only over-ear in this group whose box already contains the audio cable a seatback screen needs.
Our editorial score: 9.0 / 10
#ad Live price not shown. How this is funded
Also sold direct by Bose — we earn nothing there, so check both.
The Bose does not fold up, but the earcups rotate flat and Bose has made the hard case unusually compact for a full-size over-ear. Among the headphones that cancel at the very top of the field, it is comfortably the most packable.
The trade with a rigid case is that it holds its volume regardless. It will slide into a structured backpack beautifully and refuse to compress into a half-full tote — which is a different failure mode from being simply large.
What works on a plane
- The best low-frequency canceling in this group, which is exactly the band engine drone lives in
- The 2.5 mm-to-3.5 mm cable is in the box, so a seatback screen needs nothing extra
- Compact hard case for a full-size over-ear
- Up to 45 hours with canceling off, if you only want isolation on a train
What does not
- Immersive Audio costs you a third of the battery, dropping to 23 rated hours
- Heavier than the Sony by roughly 10 g, and clamp is firmer out of the box
- The hard case is compact but still rigid, so it will not squash into a full bag

4. Best fold-flat for a laptop bag
Sennheiser MOMENTUM 4 Wireless
Sennheiser publishes up to 60 hours. That is the difference between charging at the gate and not thinking about a charger for an entire two-week trip.
Our editorial score: 8.8 / 10
#ad Live price not shown. How this is funded
Also sold direct by Sennheiser — we earn nothing there, so check both.
Fold-flat earcups make the MOMENTUM 4’s case slim and wide. In a bag with a laptop compartment that is arguably the better geometry — it slides in alongside the machine and takes up no depth at all.
In a packing cube or a cylindrical daypack it is the worse geometry, because it keeps the full width of the headphone. This is the clearest case on this page of the right answer depending entirely on the bag rather than the headphone.
What works on a plane
- Up to 60 rated hours, roughly double the flagship norm
- The 1.2 m 3.5 mm cable is in the box, so seatback screens work straight out of the bag
- Fold-flat earcups make the carry case slim rather than deep
- The 42 mm transducer is the most relaxed listen here over a very long session
What does not
- Published measurements consistently place its noise canceling a step behind the Bose
- The case is broad, so it eats width in a personal item even though it is slim
- Fold-flat is not fold-up, so the footprint is larger than the Sony's

5. Fold-flat with the most in the case
JBL Tour One M3
The only headphone here that ships with the answer to the airline-jack problem in the box: the Smart Tx transmitter plugs into the seat and sends the movie to your headphones over Bluetooth.
Our editorial score: 8.7 / 10
#ad Live price not shown. How this is funded
Also sold direct by JBL — we earn nothing there, so check both.
Also fold-flat, with the same slim-and-wide geometry as the Sennheiser. What makes it different on this page is what else has to fit in the case: the Smart Tx transmitter, a USB-C-to-3.5 mm cable, a USB-C-to-USB-C cable and a USB-C-to-USB-A adapter.
That is a fuller kit than anything else here, and it is worth thinking about as a packing decision rather than only a feature list. You are carrying more, and you are carrying more that you would otherwise have had to buy separately.
What works on a plane
- The Smart Tx transmitter solves in-flight entertainment without a separate purchase
- Up to 40 rated hours with canceling on, comfortably over a long-haul plus layover
- Five minutes of charge buys five hours
- Both a 3.5 mm and a USB-C wired path in the box
What does not
- The Smart Tx is one more small object to lose, and it needs its own charge
- 278 g sits between the Sony and the Sennheiser without beating either at their own game
- Noise canceling is very good rather than class-leading

How we decide
How these picks were chosen
We do not run a test lab and we do not claim to have flown with these units. Every verdict on this page is one of three things: a measurement published by somebody who does own a test rig and is credited by name, a manufacturer specification we quote and then interpret against what a long flight actually demands, or a plainly-labeled editorial judgment. The five axes we score on — cabin-noise reduction, battery on a long-haul, pack size, comfort past hour three, and wired fallback — are the ones that decide a travel purchase, and the weighting is published in full.
Questions
Common questions
Which noise-canceling headphones fold the smallest?
The Sony WH-1000XM6, because it is the only current flagship that folds up — the earcups rotate and the headband collapses, producing a compact block in a magnetic-closure case. The Soundcore Space Q45 also folds up and ships a hard case.
Do AirPods Max fold?
No. Apple publishes fixed dimensions of 168.6 mm by 83.4 mm by 187.3 mm, and the Smart Case is a soft cover that adds 134.5 g while leaving the headband exposed. This is the biggest practical difference between them and the Sony for a traveler.
What is the difference between fold-up and fold-flat?
Fold-up collapses the headband as well as rotating the cups, giving a compact block. Fold-flat only rotates the cups into the plane of the headband, giving a thin but full-width object. Fold-up suits a packing cube; fold-flat suits a laptop compartment.
Will a folding hinge break?
It is the most common point of eventual mechanical failure on a headphone, but it takes years and it is largely preventable. Fold into the supplied case rather than putting the folded headphone loose into a bag, which is what applies the loads that stress a hinge.
Is a hard case better than a soft one for travel?
For protection, clearly. For packing, not always — a rigid case holds its volume no matter how much you want it not to, so it is excellent in a structured backpack and awkward in a soft bag you were hoping to compress. A small rigid case is the best of both, and only three headphones here ship one.
