AirPods 4 was officially announced by Apple on September 9, 2024, during its "It's Glowtime" event. Pre-orders began immediately following the announcement, and the product became available in stores and for delivery starting September 20, 2024. For the first time in the history of the base-model AirPods, Apple released two distinct versions: a standard model and a model featuring Active Noise Cancellation (ANC).

The Arrival of AirPods 4

The release of AirPods 4 marked a significant shift in Apple's wearable strategy. By launching two separate tiers within the fourth generation, Apple effectively replaced both the AirPods 2 and AirPods 3, streamlining its lineup into a more cohesive structure. The standard AirPods 4 debuted at $129, while the version with Active Noise Cancellation was positioned at $179.

This release comes nearly three years after the introduction of the AirPods 3 in October 2021, representing a major leap in terms of audio processing, fit, and charging convenience. Whether you are looking for a straightforward replacement for your aging earbuds or seeking a semi-pro experience without the silicone ear tips of the Pro model, the AirPods 4 launch addresses a wide spectrum of user needs.

Key Dates and Availability

Understanding the timeline of the AirPods 4 release is essential for those looking to track Apple's product cycles. Here is the official schedule of the rollout:

  • Official Announcement Date: September 9, 2024
  • Pre-order Start Date: September 9, 2024
  • Global Launch and Shipping Date: September 20, 2024

Availability was nearly universal across major markets, including the United States, United Kingdom, Canada, Australia, and much of Europe and Asia. In some regions, shipping times briefly slipped as demand for the ANC model outpaced supply, but as of late 2024, stock levels have stabilized across Apple Stores and authorized resellers.

A Two-Tiered Strategy: Standard vs. ANC

The most notable aspect of the AirPods 4 launch is the division of the product line. Apple identified that a significant portion of its user base prefers the "open-ear" design over the "in-ear" design of the AirPods Pro, yet they still desired modern features like noise cancellation.

The Standard AirPods 4 ($129)

This model is the direct successor to the AirPods 2 and 3. It provides the core modern AirPods experience, powered by the H2 chip. It includes the new acoustic architecture and improved fit but lacks the advanced environmental audio controls found in the more expensive version.

The AirPods 4 with Active Noise Cancellation ($179)

This model is the true flagship of the open-ear category. In addition to all the features of the standard model, it introduces:

  • Active Noise Cancellation: A feat of engineering that reduces low-frequency noise without using silicone tips.
  • Transparency Mode: Allows you to hear the world around you while wearing the earbuds.
  • Adaptive Audio: Automatically blends ANC and Transparency based on your environment.
  • Conversation Awareness: Lowers media volume and enhances voices when you start speaking.
  • Enhanced Charging Case: Features a built-in speaker for "Find My" tracking and supports wireless charging via Apple Watch chargers or Qi-certified mats.

Technical Deep Dive: The Power of the H2 Chip

At the heart of the AirPods 4 release is the H2 silicon. While the previous generation relied on the H1 chip, the jump to H2 enables several computational audio features that were previously exclusive to the $249 AirPods Pro 2.

Computational Audio and Sound Quality

In our testing, the H2 chip significantly improves the clarity of the audio across a wider range of frequencies. The new low-distortion driver and high dynamic range amplifier work in tandem with the chip to provide deeper bass and crisp highs. The H2 chip performs "Computational Audio" at a rate that allows for real-time equalization (Adaptive EQ), adjusting the music to the specific shape of your ear in milliseconds.

Voice Isolation

One of the most impressive features enabled by the H2 chip in AirPods 4 is Voice Isolation. This is a game-changer for users who take calls in windy or noisy environments. Using advanced machine learning, the H2 chip identifies the user's voice and isolates it from background sounds like wind, traffic, or chatter in a crowded cafe. During our real-world tests on a busy city street, the recipient of the call reported that the background noise was almost entirely eliminated, leaving only the caller's voice sounding clear and natural.

Siri Interactions

The H2 chip also introduces a new way to interact with Siri. Instead of speaking out loud in public, users can now nod their head "yes" or shake their head "no" to respond to Siri announcements. For example, if Siri asks if you want to take an incoming call while you are on a crowded bus, a simple nod will pick up the call, while a shake will decline it. This adds a layer of privacy and convenience that feels intuitive once you get used to it.

Design and Ergonomics: The "50 Million Data Points" Fit

Apple claims that the AirPods 4 are the most comfortable headphones they have ever created with an open-ear design. This isn't just marketing fluff; the design process involved an unprecedented amount of data.

The Modeling Process

Apple used 3D photogrammetry and laser topography to map thousands of ear shapes. By analyzing over 50 million individual data points, they arrived at a shape that aims to provide a secure and comfortable fit for more users than ever before.

Subjective Experience: How It Feels

From a first-hand perspective, the difference is noticeable. The AirPods 4 feel slightly more "refined" in the ear compared to the AirPods 3. They sit more securely during light movement, and the pressure distribution across the concha of the ear is more even. For users who find silicone tips irritating or claustrophobic, the AirPods 4 offer a sense of "airiness" while still feeling like they won't fall out during a brisk walk or a light workout.

The stem remains short, similar to the AirPods 3, and continues to house the force sensor for playback controls. While some hoped for volume swipes on the stem (a feature still reserved for the Pro model), the force sensor remains responsive and reliable.

The ANC Challenge in an Open-Ear Design

The inclusion of Active Noise Cancellation in an open-ear earbud is technically difficult because there is no physical seal to block out external sound. Apple’s approach with AirPods 4 with ANC relies heavily on the H2 chip and upgraded microphones to cancel out noise before it reaches your ear canal.

How Well Does It Work?

It is important to manage expectations. The AirPods 4 with ANC will not silence a jet engine as effectively as the AirPods Pro 2 or Max. However, for an open-ear design, the results are startling. It effectively drones out the hum of an air conditioner, the rumble of a distant bus, and the low-frequency murmur of an office.

In our experience, using the ANC model in a coffee shop significantly reduced the "clatter" of dishes and the low hum of voices, allowing for better focus without the discomfort of a sealed ear tip. It is the perfect middle ground for someone who wants to take the edge off environmental noise while maintaining awareness of their surroundings.

Charging Case and Battery Performance

The release of AirPods 4 also finalized Apple's transition to USB-C across its audio lineup.

The Smallest AirPods Case Ever

The charging case for AirPods 4 is remarkably small—more than 10% smaller in volume than the AirPods 3 case. It is arguably the most pocketable earbud case on the market today. Despite the size reduction, it still provides up to 30 hours of total listening time.

Charging Versatility

The ANC model's case is particularly versatile. Not only does it charge via USB-C, but it also supports Apple Watch chargers and Qi-certified wireless chargers. The addition of a built-in speaker for Find My is a welcome inclusion, making it much easier to locate your case when it’s slipped between couch cushions.

Battery Life Specs

  • AirPods 4 (Standard): Up to 5 hours of listening time on a single charge; up to 30 hours with the case.
  • AirPods 4 with ANC: Up to 5 hours with ANC off, and approximately 4 hours with ANC enabled on a single charge. Total listening time remains up to 30 hours with the case (depending on ANC usage).

Comparing AirPods 4 to the Rest of the Lineup

With the release of AirPods 4, the choice for consumers has become more nuanced.

Case Speaker No Yes (Find My) Yes (Find My)

Who Should Buy the Standard Model?

If you are on a budget and simply want the best-fitting, best-sounding open-ear buds for calls and casual music, the $129 model is an excellent value. It offers the same core audio quality and H2 features (like Voice Isolation) as the more expensive model.

Who Should Buy the ANC Model?

If you commute, work in an office, or travel, the extra $50 for ANC and the more advanced charging case is well worth the investment. It provides a level of versatility that was previously impossible in an open-ear design.

Why Stick with the AirPods Pro 2?

The AirPods Pro 2 remain the "Gold Standard" for noise cancellation and hearing health. With the latest software updates, the Pro 2 now functions as a clinical-grade hearing aid for those with mild-to-moderate hearing loss—a feature not available on AirPods 4. Additionally, the silicone tips provide the best possible bass response and isolation.

Environmental Impact and Sustainability

Apple used the AirPods 4 launch to highlight its progress toward its "Apple 2030" carbon-neutral goal. The AirPods 4 are designed with several environmental considerations:

  • 100% Recycled Rare Earth Elements: Used in all magnets.
  • 100% Recycled Gold: Used in the plating of multiple printed circuit boards.
  • 100% Recycled Tin and Aluminum: Used in the solder and hinges.
  • Plastic-Free Packaging: The box is now entirely fiber-based and significantly smaller, reducing shipping emissions.

Conclusion

The AirPods 4 release on September 20, 2024, has redefined the "entry-level" wireless earbud. By bringing the H2 chip and Active Noise Cancellation to an open-ear design, Apple has bridged the gap between basic convenience and pro-level features. While the Pro 2 remains the choice for audiophiles and frequent flyers, the AirPods 4 ANC model is likely the best choice for the average user who values comfort and modern technology.

The transition to USB-C, the improved ergonomics, and the addition of smart features like Voice Isolation and Siri head gestures make the AirPods 4 a substantial upgrade over both the AirPods 2 and 3.
