Which model do I have? The complete guide to model numbers

Lost an AirPod or is your charging case broken? Then you will want to know exactly which AirPods model you have. Because if you want to replace a single AirPod or charging case, it has to match your current generation exactly. A 2nd generation AirPod simply does not work together with a 3rd generation – and vice versa.

At Earbuds Restore we specialise in single AirPods and charging cases. We supply exclusively original AirPods parts, carefully tested for sound, battery and connectivity. In this extensive guide we explain step by step how to find out which AirPods you have, what the differences between the generations are, and how to choose the right replacement part.

Why it matters to know your AirPods model

Apple has released multiple generations of AirPods by now: the standard AirPods (1st, 2nd, 3rd and 4th generation) and the AirPods Pro (1st, 2nd and 3rd generation). Although they look similar at first glance, they are not technically interchangeable. Each generation has its own chip, drivers and firmware.

In practice this means:

• A single 2nd generation AirPod cannot be paired with a 3rd generation AirPod
• AirPods Pro 1 earbuds do not fit in an AirPods Pro 2 charging case (and vice versa)
• The AirPods 3 charging case does not work with AirPods 2 earbuds
• Even within the Pro line, generation 1 and 2 are not compatible

Before you order a single AirPod or separate charging case, it is therefore essential to identify your exact model first. Fortunately, that is easier than you might think.

How to find your AirPods model via your iPhone

The quickest way to discover which AirPods you have is via your iPhone or iPad. Follow these steps:

The model number always starts with the letter "A" followed by four digits, for example A2032 or A2931. With this number you can look up exactly which generation you have in the table below.

Model number on the charging case or on the earbud itself

Besides the digital method via your iPhone, you can also find the model number physically:

On the charging case

Open the lid of your charging case and look at the inside of the lid. The model number of the case is printed there in small letters. On some models it is on the bottom of the case, close to the Lightning or USB-C port.

On the earbud

Each AirPods earbud also has its own model number. It is printed in very small letters on the stem of the AirPod, on the inside (the side that faces your face when you wear the AirPod). You may need a magnifying glass or your phone's camera to read it.

Overview table: model number → official name → generation

Below you will find a complete overview of all AirPods model numbers, so you can determine exactly which generation you have:

The third numbers (e.g. A3054, A2931, A3049) are worldwide/regional variants of the same model. You can read the exact number on the earbud itself or via Settings > Bluetooth > (i).

How do I know whether I need a single AirPod, a charging case or a complete set?

Not everyone needs the same thing. Depending on your situation, it is smart to replace just one part instead of buying a full set:

When should you buy a single left or right AirPod?

• You have lost one AirPod (the other still works fine)
• One AirPod is broken or its battery drains much faster than the other
• The sound in one earbud has become noticeably worse

In these cases you simply order a single left or right AirPod of the same generation.

When does a new charging case make more sense?

• You have lost your case but your earbuds still work
• The case no longer charges (broken port or battery)
• The lid no longer closes properly
• You want to upgrade to a case with wireless charging

Then take a look at our separate charging cases and pick the right one for your generation.

Compatibility per generation (combining a single AirPod)

A frequently asked question is: "Can I combine a new single AirPod with my existing AirPod?" The answer is yes, as long as it is the same generation. Here is an overview:

Earbuds Restore supplies exclusively original AirPods parts. That is why pairing goes just as smoothly as with a new set from Apple. Your new single AirPod is recognised automatically and works with your existing earbud right away.

How do you pair a new single AirPod or charging case?

Received a replacement AirPod or charging case? Pairing is simple. Follow these steps:

1. Place your new AirPod (or both AirPods) in the charging case
2. Close the lid and wait 30 seconds
3. Open the lid and hold the case close to your iPhone
4. An animation appears on your iPhone – tap Connect
5. Follow the on-screen instructions to complete the setup
6. Done! Your AirPods are now paired and ready to use

When is it smart to replace your AirPods?

AirPods do not last forever. After about 2-3 years of intensive use you will notice the battery does not last as long. That is normal for lithium-ion batteries. But when is replacement really necessary?

• Short battery life: When your AirPods only last 1-2 hours instead of 4-5 hours
• One side lost: A single replacement is then much cheaper than a new set
• Sound issues: Crackling sound, volume differences, or problems with noise cancellation
• Connection issues: AirPods that keep losing the connection or no longer pair
• Physical damage: Broken case, cracked earbud, or sensors that no longer work

A single AirPod or charging case is often the smarter and more sustainable choice. You save money and avoid unnecessary electronic waste.
