Are AirPods (1st and 2nd Generation) the Same Size? The Definitive Guide

Yes, the AirPods (1st generation) and AirPods (2nd generation) are virtually identical in size and shape. This means they are largely interchangeable in terms of fit, compatibility with accessories, and overall feel in your ear.

A Closer Look at AirPods Dimensions and Design

While the performance and internal components of Apple’s AirPods received updates between the first and second generations, the exterior design remained remarkably consistent. This was a deliberate choice, allowing existing users to easily upgrade without needing new cases or adjusting to a different fit. Let’s delve into the specifics:

AirPods (1st Generation) – A Pioneering Design

The original AirPods, released in 2016, introduced a radical new concept for truly wireless earbuds. Their dimensions were meticulously crafted to strike a balance between comfort, stability, and audio quality. They measured approximately:

Height: 40.5 mm (1.59 inches)
Width: 16.5 mm (0.65 inches)
Depth: 18.0 mm (0.71 inches)
Weight: 4 g (0.14 ounces) per AirPod

The charging case, crucial for power and storage, was also precisely sized for portability:

Height: 53.5 mm (2.11 inches)
Width: 44.3 mm (1.74 inches)
Depth: 21.3 mm (0.84 inches)
Weight: 38 g (1.34 ounces)

AirPods (2nd Generation) – Evolution, Not Revolution

Released in 2019, the second-generation AirPods brought advancements like the H1 chip for faster pairing, “Hey Siri” support, and an optional wireless charging case. However, visually, they were nearly indistinguishable from their predecessors. The dimensions remained effectively the same:

Height: 40.5 mm (1.59 inches)
Width: 16.5 mm (0.65 inches)
Depth: 18.0 mm (0.71 inches)
Weight: 4 g (0.14 ounces) per AirPod

The standard charging case mirrored the first-generation case in size. The optional Wireless Charging Case maintained the same height, width, and depth, but was slightly heavier at 40 g (1.41 ounces) due to the inclusion of wireless charging circuitry. This slight weight difference is hardly noticeable in everyday use.

Why the Consistent Design?

Apple’s decision to maintain the same external dimensions had several benefits:

Compatibility: Existing users could upgrade to the 2nd generation AirPods without needing to replace their cases, ear hooks, or other accessories.
Familiarity: Users were already accustomed to the fit and feel of the original AirPods, ensuring a seamless transition to the new model.
Production Efficiency: Maintaining the same form factor streamlined manufacturing processes and reduced production costs.

Minute, But Important, Differences

While the overall size is identical, there is one subtle visual difference between the charging cases. The 2nd generation charging case has its setup/pairing button moved slightly lower on the back of the case. This change doesn’t affect usability but is the most reliable way to visually differentiate the cases from each other.

AirPods (1st & 2nd Generation) – Frequently Asked Questions (FAQs)

To further clarify the similarities and differences between the first and second-generation AirPods, here are some frequently asked questions:

FAQ 1: Can I use my first-generation AirPods case with my second-generation AirPods?

Yes, you can use your first-generation AirPods charging case with your second-generation AirPods, as long as it’s not the wireless charging case. The standard charging case is fully compatible.

FAQ 2: Are the AirPods (1st and 2nd generation) interchangeable in the case?

Yes, the individual AirPods are fully interchangeable. You can use a left AirPod from the first generation with a right AirPod from the second generation, and vice versa, inside either the original or standard 2nd generation charging case.

FAQ 3: Will my AirPods 1st generation ear hooks fit the AirPods 2nd generation?

Absolutely. Because the external dimensions are the same, any ear hooks designed for the original AirPods will fit the second-generation model perfectly.

FAQ 4: Does the wireless charging case work with the first-generation AirPods?

Yes, the wireless charging case designed for the second-generation AirPods is compatible with the first-generation AirPods. You can charge your original AirPods in the wireless charging case.

FAQ 5: Can I tell the difference between the first and second-generation AirPods just by looking at them?

It’s extremely difficult. The AirPods themselves are visually identical. The primary visual cue is the position of the setup button on the charging case. The second-generation case, with the standard charging capability, has its button slightly lower. Also, if the case supports wireless charging, it’s a second-generation case.

FAQ 6: Are there any performance differences between the first and second-generation AirPods in terms of sound quality?

The sound quality is generally considered similar. While the second-generation AirPods feature the newer H1 chip, which provides enhanced processing, the core audio components remained largely unchanged. Most users find the sonic differences to be negligible.

FAQ 7: What is the main advantage of the second-generation AirPods over the first?

The primary advantage is the H1 chip, which enables faster pairing with Apple devices, more stable wireless connections, and support for “Hey Siri” voice activation.

FAQ 8: Do both generations of AirPods have the same battery life?

The battery life for audio playback and talk time is comparable between the two generations. Apple claims similar battery performance for both models.

FAQ 9: Are accessories like skins and stickers interchangeable between the two generations?

Yes, any skin, sticker, or other cosmetic accessory designed to fit the original AirPods or charging case will also fit the second-generation model, provided it is not specifically designed to cover the charging case button.

FAQ 10: Is it worth upgrading from the first-generation AirPods to the second?

The value of upgrading depends on your individual needs and priorities. If you value faster pairing, hands-free “Hey Siri” functionality, and potentially slightly improved call quality, the upgrade may be worthwhile. However, if you are satisfied with the performance of your first-generation AirPods, there may not be a compelling reason to upgrade.

FAQ 11: Do both generations of AirPods support spatial audio?

No, spatial audio is supported only on later AirPods models, specifically the AirPods 3rd generation, AirPods Pro, and AirPods Max. First and second-generation AirPods do not have this feature.

FAQ 12: How can I identify which generation of AirPods I have?

The easiest way to identify your AirPods generation is by checking the model number, located inside the charging case lid, on the original box, or in your iPhone’s settings.

AirPods (1st generation): A1523, A1722 (AirPods); A1602 (Charging Case)
AirPods (2nd generation): A2032, A2031 (AirPods); A1602 (Charging Case – standard); A1938 (Charging Case – wireless)

By examining these details, you can quickly and accurately determine which generation of AirPods you own. Hopefully, this comprehensive guide has answered all of your questions about the size and compatibility of the first and second-generation AirPods.
