Apple has officially launched AirPods 4, sparking excitement among tech enthusiasts and music lovers alike. Engadget provides an exclusive look into the development process of these innovative earbuds, detailing interesting revelations about their design and functionality.

Meet the "Snorkel" Design

One of the standout aspects of the new AirPods is the quirky internal name given to their front end: "snorkel." This term resonates with the bold approach Apple has taken in redesigning the AirPods to enhance performance. Unlike AirPods 3, the new version incorporates a unique angle and positioning of the drivers, now precisely directed down the ear canal. This adjustment was necessary to prevent sound reflections from interfering with the internal microphone—an important feature for the active noise cancellation (ANC) technology.

Challenging Noise-Cancellation in Open-Ear Design

Apple's engineering team revealed the complexities of integrating ANC into an open-ear design. Unlike their predecessors, the AirPods Pro 2 and AirPods Max, the AirPods 4 must manage significantly higher levels of environmental noise. The responsibility for this challenge falls heavily on the H2 chip, which has been uniquely optimized for these earbuds.

Marketing director Eric Treski emphasized, “Creating exceptional ANC quality in an ear-tip-less product is extraordinarily difficult. The capabilities of the H2 chip allow us to manage ANC effectively while also continually monitoring and cancelling surrounding environmental noise.” Transparency mode, which mixes ambient sounds with audio from the user’s surroundings, also leverages this technology to ensure seamless auditory experiences without perceptible delays.

The Journey of Development

The intriguing backstory of AirPods 4’s development is almost as compelling as the product itself. The team began exploring the viability of ANC in standard AirPods during the "dark days of COVID," around 2020. After refining their ideas, they presented their findings to Apple executives in 2021, leading to the go-ahead for mass production. Kate Bergeron, Apple’s VP of Hardware Engineering, reminisced about that pivotal moment: “We were just blown away. We knew we struck gold and had to pursue it aggressively.”

What began as a conceptual experiment has now flourished into a premium product, remarkably evolving since the initial release of ANC in AirPods Pro.

Conclusion: A Must-Try for Audiophiles!

With their innovative design and cutting-edge audio technology, the AirPods 4 are more than just a refresh; they represent a significant leap forward in audio engineering. Whether you’re commuting, working out, or enjoying music at home, these earbuds promise to deliver an immersive listening experience like no other.
