Short answer: AirPods Pro turn a pair of earbuds into three everyday tools at once: Live Translation that speaks another language into your ear, a Hearing Test plus an FDA-authorized Hearing Aid feature for adults with perceived mild to moderate hearing loss, and a fit test that checks whether your ear tips actually seal. The catch is the phone in your pocket matters as much as the earbuds — Live Translation needs an iPhone 15 Pro or later with iOS 26 or later and Apple Intelligence turned on, while the hearing features are limited to AirPods Pro 2 and Pro 3. Get the fit right first, then set up translation and hearing in that order, and you will avoid most of the frustration people report with these features.
This guide walks through all three features in practical order: fit, translation, and hearing health. It covers what each feature needs, how to set it up step by step, where the honest limits sit, and how to decide whether AirPods Pro 3 are worth it if you already own AirPods Pro 2. Prices quoted are Apple's US list prices at the time of writing; street prices and regional prices vary, so check Apple's store in your country before buying.
Start with fit: nothing else works well without a seal
Every headline feature on AirPods Pro depends on the silicone tip sealing your ear canal. A poor seal weakens bass, weakens Active Noise Cancellation, and can make hearing measurements less reliable. Apple says a properly fitted pair should feel snug and secure without excessive pressure, and it recommends wearing a new size for 10 to 15 minutes during normal activity, such as walking, before judging it.
AirPods Pro 3 ship with five ear tip sizes — XXS, XS, S, M, and L — with size M preinstalled. That is a genuine improvement over earlier generations: the first-generation AirPods Pro did not include XS or XXS tips, and AirPods Pro 2 did not include XXS. If you have small ear canals, or if one ear has always felt different from the other, the extra sizes are worth trying rather than settling for M. Apple notes that the best tip size for heart-rate sensor accuracy on AirPods Pro 3 may differ from the best size for acoustic seal, so if you use both features, test each goal separately.
How to run the acoustic seal test
- Put both AirPods Pro in your ears and confirm they are connected to your iPhone or iPad.
- Open Settings, then tap the name of your AirPods Pro near the top of the screen.
- Tap Test Acoustic Seal (on older software this is labelled Ear Tip Fit Test) and follow the on-screen instructions.
- If the result suggests a change, first try adjusting the position of the earbuds — Apple suggests rotating the stem toward your face and pressing gently to secure the fit — then retest before switching sizes.
- If the same result repeats, try a different tip size. It is completely normal to need a different size in each ear.
Two warning signs point to the wrong size before you even run the test: tips that feel loose or fall out when you move your head are usually too small, while tips that feel compressed or uncomfortable are usually too big. A tip that passes the seal test but hurts after 30 minutes is still the wrong tip — comfort over a full day matters more than a single green result.
Practical tip: swap tips over a clean surface, keep the spares in the case pouch or a small labelled bag, and re-run the seal test after any change. Tips wear out over time, so if noise cancellation suddenly feels weaker, check the tips before assuming the hardware has failed.
Live Translation: a real-time interpreter in your ear
Live Translation is Apple's Apple Intelligence feature that translates a nearby speaker's words and plays them in your ears in your own language, while your iPhone shows a running transcript. When both people wear supported AirPods, each person hears the conversation translated into their own language. Apple labels the setting Live Translation (Beta), which is a fair warning: this is a young feature, and Apple itself notes that it uses generative models whose outputs may be inaccurate, unexpected, or offensive. Do not rely on it for medical, legal, or safety-critical conversations without a human interpreter to confirm anything important.
What you need before it will even appear
Apple Support lists a short, strict checklist. Miss one item and the option simply may not show up:
- Supported AirPods: AirPods 4 with Active Noise Cancellation, AirPods 5 (both models), AirPods Pro 2, AirPods Pro 3, or AirPods Max 2, with the latest firmware.
- Supported iPhone: iPhone 15 Pro or later. The standard iPhone 15 and iPhone 15 Plus do not qualify, because they do not support Apple Intelligence.
- Software: iOS 26 or later, with Apple Intelligence turned on.
- App: Apple's Translate app must be installed — if you deleted it, reinstall it from the App Store.
- Languages: You must download both languages — the language the other person speaks and the language you want to hear — before the conversation starts.
That last point is the one travellers most often miss. Download both language packs at home on Wi-Fi, not at the airport. Once the language models are downloaded, Apple says all processing takes place on your iPhone, where your conversation data remains private. That on-device design is also why the iPhone requirement is so strict: the earbuds are not doing the translating, your phone is.
Supported languages
Apple's Live Translation with AirPods supports Chinese (Mandarin, Simplified and Traditional), English (UK and US), French (France), German (Germany), Italian, Japanese, Korean, Portuguese (Brazil), and Spanish (Spain). Simplified Chinese is not available in mainland China, and some features may not be available in all regions or languages, so check Apple's feature-availability page for your country before travelling specifically for this feature.
How to set it up and start a conversation
- Wear your AirPods and confirm they are connected.
- Go to Settings, tap your AirPods name, then tap Live Translation (Beta) and then Languages.
- Download your language and the other person's language.
- To start, open the Translate app and tap Live, squeeze both AirPods stems, or ask Siri to start Live Translation.
- Speak naturally and pause between thoughts. Short, complete sentences translate far more reliably than long, rambling ones.
In practice, Live Translation works best for the situations it was designed for: ordering food, asking directions, checking into a hotel, and chatting with relatives. It is not a document translator and it does not translate websites. Background noise, strong accents, slang, and overlapping speech all reduce accuracy, so step somewhere quieter when the conversation matters.
One honest comparison: rivals such as Google's Pixel Buds work with far more languages through Google Translate, while Apple's list is deliberately short. Apple's trade-off is depth over breadth — translation built into the earbuds and the phone you already carry, processed on-device once languages are downloaded, rather than a wider list routed through the cloud. If your language pair is not on Apple's list, Live Translation is not the tool for that trip, no matter which AirPods you buy.
Hearing health: a five-minute test and a real hearing aid feature
AirPods Pro 2 and AirPods Pro 3 include three hearing-health features: a Hearing Test, a Hearing Aid feature, and Hearing Protection (also called Loud Sound Reduction). The Hearing Test and Hearing Aid feature are not available on AirPods 4, AirPods 5, or AirPods Max models, so if hearing support is your main reason for buying, make sure you are buying a Pro model.
The Hearing Test: a screening, not a diagnosis
The Hearing Test takes about five minutes. You need AirPods Pro 2 or Pro 3 with current firmware, a compatible iPhone or iPad with iOS 18 or iPadOS 18 or later, and a quiet room. The test plays tones at different frequencies and volumes, and you tap whenever you hear one. The result is saved as an audiogram in the Health app, which you can export as a PDF and share with a clinician.
Be clear about what this is: a screening tool, not a full hearing evaluation. If results keep pointing the same way, or if daily listening feels difficult, take the exported audiogram to a licensed audiologist. Apple advises seeking medical advice for difficulty hearing or a sudden change in hearing, and that advice should be followed rather than explained away.
The Hearing Aid feature: what the FDA authorization actually means
On September 12, 2024, the US Food and Drug Administration authorized Apple's Hearing Aid feature through its De Novo pathway, describing it as the first over-the-counter hearing aid software device. It is intended for adults aged 18 and older with perceived mild to moderate hearing impairment. The FDA's clinical evaluation involved 118 participants with perceived mild to moderate hearing loss, and found that people using the self-fitting approach achieved similar perceived benefit to participants who received professional fitting of the same device.
That authorization is meaningful but narrow. It covers mild to moderate loss only — not severe or profound loss — and it covers adults only. If your test shows more than mild to moderate loss, or if you have pain, discharge, dizziness, or sudden hearing change, AirPods Pro are not a substitute for professional care.
Setup is straightforward once you have a result:
- Wear your AirPods Pro and open Settings, then tap your AirPods name.
- Open Hearing Assistance and choose your recent Apple Hearing Test result, or add an audiogram from a clinic.
- Follow the setup flow to turn on the Hearing Aid feature and adjust comfort levels.
- Test it in a real conversation, not just in a quiet room. Restaurants and group conversations are where the benefit — or the limits — show up.
Hearing Protection and everyday listening
Hearing Protection reduces loud environmental noise when you are in Transparency mode, and it works alongside the other hearing features. Apple notes it is not suitable for protection against extremely loud impulse sounds such as gunfire, fireworks, or jackhammers, or against sustained sounds louder than 110 dBA — so it is a daily-listening safeguard, not industrial hearing protection.
For everyday use, two habits protect your hearing more than any feature: keep volumes moderate, and let the iPhone's headphone audio level notifications actually change your behaviour. The Health app records headphone audio levels over time, which makes it easy to spot a creeping volume habit before it becomes a problem.
AirPods Pro 2 vs Pro 3: which one fits this guide?
| Feature | AirPods Pro 2 | AirPods Pro 3 |
|---|---|---|
| Live Translation | Yes, with latest firmware and a supported iPhone | Yes, with latest firmware and a supported iPhone |
| Hearing Test and Hearing Aid | Yes | Yes |
| Ear tip sizes in the box | XS, S, M, L (no XXS) | XXS, XS, S, M, L |
| Listening with noise cancellation | Up to 6 hours per charge; up to 30 hours total with the case | Up to 8 hours per charge; up to 24 hours total with the case |
| Listening in Transparency with Hearing Aid | Up to 10 hours per charge on Pro models in this mode | Up to 10 hours per charge in Transparency using the Hearing Aid feature |
| Heart-rate sensing during workouts | No | Yes, with the Fitness app or compatible apps |
| US list price | Often discounted since Pro 3 launched (check current retailer pricing) | $249 |
The honest verdict: if you already own AirPods Pro 2, you already own the translation and hearing features in this guide — Pro 3 adds a better seal range, stronger noise cancellation (Apple claims up to twice as effective as Pro 2, and up to three times that of AirPods 5 under IEC 60268-24 testing), longer per-charge listening, and heart-rate sensing, but it is not required to unlock this guide. If you are buying fresh, Pro 3 is the straightforward pick at the same $249 list price, especially if small ear tips or workout heart-rate tracking matter to you. Note the battery trade-off honestly: Pro 3 lasts longer per charge but offers less total time with the case (24 hours vs 30 hours), so heavy travellers who rarely charge the case may actually prefer keeping Pro 2 charged differently — or simply packing a cable.
Everyday-use checklist
- Before a trip: download both translation languages, re-run the seal test with the tips you will travel with, and charge the case fully — Pro 3 gives up to 8 hours per charge with noise cancellation, but only 24 hours total with the case.
- Before an important conversation: test translation with a friend first, in a quiet room, with short sentences. Confirm anything critical through a second channel.
- Every few months: re-check tip fit, clean tips gently, and re-run the Hearing Test in the same quiet room so results stay comparable.
- If hearing feels worse suddenly: stop self-fitting and seek professional advice promptly rather than turning the volume up.
- If Live Translation does not appear: check, in order, iPhone model (15 Pro or later), iOS version (26 or later), Apple Intelligence on, Translate app installed, AirPods firmware current, and both languages downloaded.
The bottom line is simple. AirPods Pro are at their best when you treat them as a system — tips, phone, software, and downloaded languages all in place — rather than as earbuds that magically translate and protect hearing on their own. Set the fit once, download languages before you need them, take the hearing test in a quiet room, and keep a human interpreter and a clinician in the loop wherever the stakes are high. Done that way, these are genuinely useful everyday features, not just launch-event demos.
Frequently Asked Questions
Do I need AirPods Pro 3 for Live Translation, or will Pro 2 work?
AirPods Pro 2 work. Apple lists AirPods Pro 2 and Pro 3, plus AirPods 4 with Active Noise Cancellation, AirPods 5, and AirPods Max 2, all with the latest firmware, paired with an iPhone 15 Pro or later running iOS 26 or later with Apple Intelligence turned on. The iPhone requirement is the real gate, not the earbud generation.
Which languages does Live Translation with AirPods support?
Chinese (Mandarin, Simplified and Traditional), English (UK and US), French (France), German (Germany), Italian, Japanese, Korean, Portuguese (Brazil), and Spanish (Spain). Simplified Chinese is not available in mainland China, and availability varies by region, so check Apple's feature-availability page before travelling.
Does Live Translation work without the internet?
Once both language models are downloaded to your iPhone, Apple says all processing takes place on your iPhone. Download both languages on Wi-Fi before you need them, since you cannot download a language pack in the middle of a conversation without a connection.
Can AirPods Pro replace a prescription hearing aid?
No — not for everyone. Apple's Hearing Aid feature is FDA-authorized for adults aged 18 and older with perceived mild to moderate hearing impairment only. It is not intended for severe or profound loss, and the five-minute Hearing Test is a screening tool, not a full evaluation. If results suggest more than mild to moderate loss, or hearing changes suddenly, see a licensed audiologist.
How do I know which ear tip size is right?
Start with the preinstalled M tips, wear them for 10 to 15 minutes during normal activity, then run the Test Acoustic Seal in Settings under your AirPods name. If it suggests a change, adjust position first, then try another size. Different sizes in each ear are normal, and on Pro 3 the best size for heart-rate accuracy may differ from the best size for seal.
Is the Hearing Aid feature available everywhere?
No. Apple notes the hearing features may not be available in all regions or languages, and the FDA authorization described here is a US authorization. Check Apple's current availability page for your country, and confirm the feature appears in Settings before buying for this purpose.
