A model-specific case - like this AirPods 4 cover - is the only way to get a correct fit. AirPods 4 and Pro 2 cases aren't interchangeable.
If you're wondering about AirPods 4 case compatibility with the AirPods Pro 2 - whether one case can cover both, or whether a spare you already own will fit - here's the short answer up front: no. AirPods 4 cases and AirPods Pro 2 cases are different physical sizes with different charging and feature layouts, so a case built for one will not fit or properly function on the other.
Quick answer
No, AirPods 4 and AirPods Pro 2 cases are not interchangeable. The Pro 2 charging case is about 10 mm wider than the AirPods 4 case, and the two have different ports, speakers and charging features. Always buy a case made for your exact model.
That's the verdict, but the why is worth understanding - partly so you buy correctly, and partly because the differences explain a lot about what each case can and can't do. Below you'll find the exact dimensions, a clear feature-by-feature breakdown, and a simple way to make sure you get the right case the first time.
Why an AirPods 4 Case Won't Fit a Pro 2 (and Vice Versa)

The simplest reason is shape. The AirPods Pro 2 earbuds have larger stems and silicone ear tips, so their charging case is built wider to hold them. The AirPods 4 earbuds are slimmer, open-fit buds, so their case is narrower. When you put the two charging cases side by side, the heights and thicknesses are close, but the Pro 2 case is clearly the wider of the two - and that width gap is what breaks compatibility.
Slip an AirPods 4 into a Pro 2 case and it rattles around, the lid won't sit right, and the cutouts miss their marks. Try the reverse and the Pro 2 case simply won't close over the wider Pro 2 - sorry, the narrower AirPods 4 cover won't stretch around the wider Pro 2 charging case at all. On top of the size mismatch, the two cases put their charging ports, status lights, speakers and (on the Pro 2) the lanyard loop in different places, so even if the size were closer, the openings wouldn't line up. A protective case is molded to one specific charging case; there's no flex to span a generation.
The Pro 2 case is about 10 mm wider than the AirPods 4 case - that single gap is why they'll never swap.
A Pro 2 case (shown here with a carabiner) is molded to the wider Pro 2 charging case - it won't seat on an AirPods 4.
It helps to think about what a protective case actually is: a precise mold of one specific charging case, with openings cut exactly where that case puts its port, light and speaker. There's no stretch or give to absorb a 10 mm difference in width, and no way to relocate a cutout. That's why "close enough" never works between generations - a case that's even a couple of millimeters off will either refuse to close or leave the shell loose enough to slip, and a misplaced cutout means a port or speaker you can't reach. Manufacturers design to one model on purpose, because a cover that tried to fit several would fit none of them well.
The Exact Case Dimensions, Side by Side
Here are the official charging-case measurements for each model. Note how similar the height and depth are, and how different the width is - that middle number is the whole story.

The headline figure: the Pro 2 case is roughly 0.4 in (about 10 mm) wider than the AirPods 4 case - 60.6 mm versus about 50.1 mm - because the Pro 2 buds are larger. Heights and depths are within about a millimeter, which is exactly why people assume the cases swap, and exactly why they don't.
It's worth dwelling on that pattern for a second, because it explains a common mistake. When you hold the two cases, your eye reads them as "about the same" - they're nearly identical in the two dimensions you notice first, height and thickness. The difference lives entirely in the dimension that's hardest to eyeball: width. So the cases feel interchangeable in the hand right up until you actually try to swap a cover, at which point the 10 mm gap makes itself impossible to ignore. The weight tells the same story from another angle - the Pro 2 case is meaningfully heavier at about 1.79 oz, reflecting the larger shell and the extra hardware Apple packs into it, while the AirPods 4 case is lighter and slimmer because it's holding smaller buds and fewer features.
Charging & Feature Differences That Matter
Size aside, these cases simply do different things - and there's an important split within the AirPods 4 line that trips people up. The base AirPods 4 and the AirPods 4 with Active Noise Cancellation (ANC) have different charging cases, so "AirPods 4" isn't a single answer. Here's the accurate breakdown.
Pro 2 wireless charging is Qi and MagSafe (not Qi2/25W - that's the AirPods Pro 3 case). The AirPods 4 ANC case is a Qi "Wireless Charging Case" with no magnet array, so it isn't MagSafe.
A few things to underline, because they're the details guides routinely get wrong. The base AirPods 4 case charges by USB-C only - no wireless charging, no built-in Find My speaker, no precision-tracking chip. The AirPods 4 with ANC adds Qi wireless charging, Apple Watch-charger compatibility and a Find My speaker, but it is still not MagSafe (it has no magnet array, so it rests on a pad rather than snapping to it) and it has no lanyard loop. The AirPods Pro 2 case is the most fully featured of the group: USB-C or Lightning depending on year, Qi plus MagSafe, Apple Watch charging, a Find My speaker, a U1 precision-tracking chip and a lanyard loop.
Why does this matter for a case? Because a good protective cover has to leave all of that working. It must not block the USB-C port, the wireless-charging area (where applicable), the Find My speaker grille, or - on the Pro 2 - the lanyard loop. A cover designed for the wrong model won't just fit poorly; it can cover the very features you paid for.
The Find My speaker is the feature most worth protecting access to, and it's the one a wrong-model or poorly-designed case is most likely to muffle. On the Pro 2 and the AirPods 4 ANC, that little speaker is what chirps when you're hunting for a misplaced case, and a cover that seals over the grille turns a loud, findable case into a quiet one. The lanyard loop on the Pro 2 is the other easy-to-lose feature: it's a genuinely useful anchor point for a wrist strap or a clip, and a case that covers it takes that option away. None of this is exotic - it's just the practical reason "buy for your exact model" isn't fussy advice but the difference between a case that helps and one that quietly takes features away.
How to Buy the Right Case the First Time
It comes down to two identifications and three checks.
First, identify your exact model. Is it AirPods 4 or AirPods Pro 2? If it's AirPods 4, do you have the base or the ANC version? They share a case size but differ in charging features, so a protective case fits either, while your charging expectations should match your version. If it's AirPods Pro 2, note your port: the 2022 release uses Lightning, the 2023 update uses USB-C, and the port cutout differs.
Then run three checks on any case you're considering: does it allow charge-through (so you can charge without removing it), does it leave the Find My speaker clear (on the Pro 2 and AirPods 4 ANC), and - for the Pro 2 - does it keep the lanyard loop accessible? For the base AirPods 4, only the USB-C cutout matters since there's no wireless charging, speaker or lanyard to preserve.
30-second rule
Match the case to your exact model and, for the Pro 2, your port. Then confirm three cutouts: charging, the Find My speaker (Pro 2 and AirPods 4 ANC), and the lanyard loop (Pro 2 only). Get those right and the case will fit and function perfectly.
A couple of buying traps are worth calling out, because they catch people who otherwise did everything right. The first is the listing that says "fits AirPods Pro / Pro 2 / AirPods 4" as if one case covers all three - read those carefully, because a single physical case cannot fit all of those sizes; usually it means the product is sold in model-specific variants and you must select yours at checkout. The second is buying based on a photo alone: cases for different generations look almost identical in a thumbnail, so trust the model label, not the picture. And the third is forgetting the port on a Pro 2 - a USB-C case looks right but won't seat cleanly on a Lightning case, so that one detail is worth a second look before you order.
How to Tell Which AirPods You Actually Have
Most fit mistakes start one step earlier than the case - with not being sure which AirPods you own. They look alike across generations, so here's how to settle it quickly.
Look at the buds first. AirPods Pro 2 have short stems and soft silicone ear tips that go into your ear canal, with little vents on the tips. AirPods 4 have a hard, open-fit shape with no removable tips - they rest at the opening of your ear rather than sealing it. If you see swappable rubber tips, you have a Pro model; if the buds are one smooth piece of plastic, you have AirPods 4.
Then check the case and your settings. The Pro 2 case is the wider one with a small lanyard loop on the right side; the AirPods 4 case is narrower and has no loop. For the exact model name, open the Settings app on a paired iPhone and tap the AirPods at the top - it will read "AirPods Pro" (2nd generation), "AirPods 4," or "AirPods 4 with Active Noise Cancellation." That settings screen is the definitive answer, and it also resolves the base-versus-ANC question for AirPods 4 in one glance.
Finally, confirm the port for a Pro 2. Look at the charging slot on the bottom of the case: a USB-C oval means the 2023 model, while the older flatter Lightning connector means the 2022 model. You can also check the original box or your purchase records. Once you've got the model name and, for the Pro 2, the port, you have everything you need to buy a case that fits the first time.
Fastest check
Open Settings on your iPhone and tap your AirPods at the top of the screen. The exact model name - including "with Active Noise Cancellation" for the AirPods 4 ANC - is printed right there, no guessing required.
A Note on Other AirPods Generations
Creslia airpods pro case carbon fiber protective keychain.
This guide focuses on AirPods 4 versus AirPods Pro 2, but the same principle applies across the whole lineup: every generation has its own case, and none of them cross-fit. An AirPods 4 case won't fit AirPods Pro 3, AirPods 3 or AirPods 2; a Pro 2 case won't fit any of those either. Apple changes the case size and the port, speaker and charging layout with most releases - the AirPods Pro 3 case, for example, is different again from the Pro 2 and adds newer wireless charging. There is no genuinely "universal" AirPods case that fits properly across models, so any listing claiming one fits everything is worth treating with suspicion. The safe move is always the same: match the case to your exact model.
This is also why a case you loved on an older pair won't carry over when you upgrade. Moving from AirPods 2 or AirPods 3 to AirPods 4, or from an older Pro to the Pro 2, almost always means a new case, because the charging case changed shape underneath. It's a small cost to plan for, but it's far better to know up front than to order a cover that arrives and won't close. When in doubt, the model name in your iPhone's settings plus the port on the bottom of the case are all the information a good retailer needs to point you to the right cover - and all the information you need to avoid buying the wrong one.

No. AirPods Pro 2 cases do not fit AirPods 4. The Pro 2 charging case is noticeably wider - about 60.6 mm versus roughly 50.1 mm for the AirPods 4 - because the Pro 2 earbuds have larger stems. A Pro 2 case will be too loose and won't align with the AirPods 4 port and lid, so you should always buy a case made for your exact model.
Are AirPods 4 and AirPods Pro 2 cases the same size?
No. They are similar in height and depth but differ most in width. The AirPods 4 charging case is about 46.2 by 50.1 by 21.2 mm, while the AirPods Pro 2 case is about 45.2 by 60.6 by 21.7 mm. That roughly 10 mm width difference is the main reason a case made for one will not fit the other properly.
Does the AirPods 4 case support wireless charging?
Only the AirPods 4 with Active Noise Cancellation. The ANC model has a wireless charging case that supports Qi and an Apple Watch charger in addition to USB-C. The base AirPods 4 charging case charges by USB-C only and does not support wireless charging, so check which version you own before assuming wireless will work.
Is the AirPods 4 case MagSafe?
No. The AirPods 4 with ANC has a Qi wireless charging case but no MagSafe magnet array, so it will rest on a MagSafe pad without magnetically snapping into place. MagSafe with a magnet array is a feature of the AirPods Pro 2 and AirPods Pro 3 cases, not the AirPods 4. The base AirPods 4 case has no wireless charging at all.
Will an AirPods 4 case fit AirPods Pro 3 or AirPods 3?
No. Every AirPods generation has its own case size and layout, so an AirPods 4 case will not fit AirPods Pro 3, AirPods 3, AirPods Pro 2 or AirPods 2. There is no universal AirPods case that fits properly across generations. Always match the case to your exact model to get correct cutouts, fit and charging access.
How do I know which AirPods case I need?
Identify your exact model and, for AirPods Pro 2, your port (USB-C from 2023 or Lightning from 2022). Then choose a case made specifically for that model and confirm it allows charge-through and leaves the right features clear - the USB-C port for all models, plus the Find My speaker and, on the Pro 2, the lanyard loop. Matching the model and the port is what guarantees a proper fit.
The Bottom Line
AirPods 4 and AirPods Pro 2 cases are not interchangeable, and the dimensions make it obvious why: the Pro 2 case is about 10 mm wider to hold its larger buds, and the two models route their ports, speakers, charging and lanyard features differently. Add the split between the base and ANC versions of the AirPods 4, and "will this case fit?" really does come down to knowing your exact model. Identify what you own - AirPods 4 base, AirPods 4 ANC, or AirPods Pro 2 with USB-C or Lightning - buy a case made for it, and check the charging, speaker and lanyard cutouts. Do that and the case will fit perfectly and leave every feature working, which is the entire point of protecting earbuds you use every day.
