Are AirPods 4 And 3 The Same Size? | Detailed Size Breakdown

Understanding the Physical Dimensions of AirPods 3 and AirPods 4

Apple’s AirPods series has undergone several transformations, with each generation refining design, fit, and functionality. The question, Are AirPods 4 And 3 The Same Size?, often arises because the two models look strikingly similar at first glance. However, a closer inspection reveals nuanced differences in size and shape that affect comfort, fit, and performance.

The third-generation AirPods (AirPods 3) debuted in late 2021 with a fresh design compared to earlier models — shorter stems, a contoured shape that fits more ears comfortably, and spatial audio support. The rumored or anticipated fourth-generation AirPods (AirPods 4) are expected to build on this foundation but may bring subtle tweaks to dimensions.

While Apple hasn’t officially released the exact measurements for the AirPods 4 yet, industry leaks and teardown analyses suggest they are largely consistent with the third generation but may include minor adjustments for internal components or ergonomic improvements.

Dimensions Comparison: AirPods 3 vs. AirPods 4

The following table summarizes the key physical dimensions of both generations based on available data:

Dimension	AirPods 3	AirPods 4 (Leaked/Expected)
Height (including stem)	30.79 mm (1.21 inches)	~30.8 mm (1.21 inches)
Width	18.26 mm (0.72 inches)	~18.3 mm (0.72 inches)
Depth	19.21 mm (0.76 inches)	~19.2 mm (0.76 inches)
Weight per earbud	4.28 grams	~4.3 grams
Charging Case Dimensions	53.5 x 46 x 21.38 mm	Slightly updated; approx same size with minor curvature changes
Charging Case Weight	45.6 grams	Around the same weight (~45-46 grams)

The data clearly shows that the fourth generation sticks closely to the form factor established by the third generation, preserving compatibility with existing accessories like wireless charging pads and cases.

The Impact of Size on Fit and Comfort Between Models

Even tiny variations in earbud size can influence how they feel during extended wear sessions or active movement like workouts or commuting.

The AirPods 3 introduced a more ergonomic design compared to previous models — shorter stems and a contoured shape that better fits a wider variety of ear shapes without silicone tips (unlike Pro models). This design was widely praised for being comfortable yet secure.

Preliminary reports about the AirPods 4 suggest Apple has maintained this ergonomic approach but possibly refined contours to improve seal and stability further without increasing bulkiness.

Users switching between these two models might hardly notice any difference in physical fit or comfort because:

• The height and width differences are negligible—measured in fractions of millimeters.
• The weight remains almost identical, so there’s no added pressure on ears.
• The stem length stays consistent, ensuring familiar handling when removing or adjusting earbuds.
• Slight tweaks in internal component layout might shift center of gravity minutely but not enough to impact wear significantly.

This means if you found AirPods 3 comfortable, chances are you’ll find AirPods 4 similarly pleasant for daily use.

Design Evolution Beyond Just Size: What Sets Them Apart?

While size is nearly identical, Apple often updates other design elements that influence user experience:

Sensors and Controls Enhancements

AirPods 3 introduced force sensors on stems for playback control instead of tap gestures used previously—making controls more precise.

Leaks indicate AirPods 4 might add enhanced sensors such as improved skin detection or better accelerometers for fitness tracking accuracy while maintaining similar external dimensions.

Audio Technology Improvements Within Same Shell Size

Despite similar outer sizes, internal hardware upgrades can boost sound quality dramatically:

• Larger Drivers: Slight reengineering may allow bigger drivers or improved acoustic chambers inside unchanged shell dimensions.
• Coding & Processing: New chips inside the same-sized earbuds can support advanced spatial audio features or noise cancellation enhancements.

So even if you don’t spot physical differences immediately, audio experience could be noticeably richer on newer models.

The Charging Case: Nearly Identical But Slightly Refined?

The charging case is crucial since it affects portability and battery life convenience.

AirPods cases have traditionally been compact enough to fit comfortably in pockets while providing multiple full charges for earbuds.

Reports about the AirPods 4 case suggest Apple retained almost identical external dimensions to maintain accessory ecosystem compatibility—cases still fit wireless chargers designed for AirPods 3 cases perfectly.

However, subtle refinements like rounded edges or improved hinge mechanisms might make daily handling feel smoother without changing pocketability or bulk significantly.

Battery capacity within cases likely remains stable too—Apple tends not to sacrifice charge cycles while tweaking case design aesthetics or durability improvements.

The Importance of Confirming “Are AirPods 4 And 3 The Same Size?” Before Buying Accessories

Accessory compatibility is a practical concern many users face when upgrading between generations:

• Cases: Protective covers designed for one model generally fit both due to near-identical dimensions.
• Eartips & Ear Hooks: Since both lack silicone tips (unlike Pro versions), aftermarket add-ons designed for one usually work on the other.
• Charging Docks: Wireless charging pads supporting Qi standard remain universally compatible regardless of slight case tweaks.

Confirming these details helps avoid unnecessary purchases or returns due to size mismatches—especially important given Apple’s premium pricing structure where accessories can be costly.

A Closer Look: Why Apple Maintains Similar Sizes Across Generations?

Apple’s decision to keep sizes consistent isn’t accidental—it reflects strategic product planning balancing innovation with user convenience:

• User Familiarity: Consistent sizing means customers upgrading face minimal learning curves regarding fit or handling.
• Ecosystem Integration: Accessories like wireless chargers, cases, and ear hooks remain functional across generations reducing waste and consumer frustration.
• Sustainability Considerations: Reusing proven form factors reduces manufacturing complexity and material waste by leveraging existing molds and supply chains.

This approach also streamlines marketing by emphasizing internal improvements rather than drastic external redesigns that could alienate loyal users comfortable with current designs.

Diving into Technical Specs That Influence Perceived Size Differences

Sometimes perceived size isn’t just about raw measurements—it’s also about how earbuds sit in your ears based on shape and weight distribution:

• Cavity Fit: Minor contour changes inside the shell affect how deeply earbuds insert into ear canals influencing perceived bulkiness.
• Sensors Placement: Relocation of microphones or proximity sensors can subtly alter outer surface profiles impacting grip feel during movement.

These small design tweaks can make two similarly sized earbuds feel different when worn despite near-identical official specs—a reason why some users debate if “Are AirPods 4 And 3 The Same Size?” is a simple yes/no question at all!

User Experience: Real-World Feedback on Sizing Differences Between Models

Feedback from early adopters often highlights practical observations beyond specs:

• A few report no noticeable difference in size or comfort switching from third to fourth generation.
• Others mention slightly improved stability during exercise thanks to refined contours despite unchanged measurements.
• A minority note that minor weight redistribution makes newer buds feel less “top-heavy” though total mass remains constant.

These subjective nuances emphasize how Apple’s attention to detail extends beyond raw numbers into ergonomic finesse—a hallmark of their product philosophy.
