# Apple AirPods 4: A New Chapter in Wireless Earbuds with Cutting-Edge ANC Technology
Apple has once again set new standards in wireless audio innovation with the launch of the **AirPods 4**. This latest iteration of AirPods presents two unique models: one that features **Active Noise Cancellation (ANC)**, integrated speakers in the case, and wireless charging capability, while the other model lacks these functionalities but includes the same **H2 audio chip** and an enhanced design. The AirPods 4 series is ready to provide users with a superior audio experience, no matter which version they select.
## The Groundbreaking ANC Without Ear Tips
A fascinating feature of the AirPods 4 is the **ANC-enabled model**, which differentiates itself with its distinctive design. In contrast to the majority of earbuds that utilize **silicone ear tips** to form a seal and augment the noise-cancellation effect, the AirPods 4 with ANC **does not include ear tips** at all. This design decision has sparked discussions, as conventional noise-canceling earbuds usually rely on a secure fit to prevent external noise.
Notwithstanding this unconventional design, preliminary reviews have lauded the **ANC capabilities** of the AirPods 4. A [review from BGR](https://bgr.com/tech/airpods-4-reviews-impressive-anc-for-open-ear-design-but-battery-life-takes-a-hit/) noted that the noise cancellation performs remarkably well, particularly when enjoying music or podcasts. This accomplishment is noteworthy, given the open-ear design of the earbuds.
### The Technology Behind ANC Without Ear Tips
In a discussion with **Engadget**, Apple’s **Vice President of Hardware Engineering, Kate Bergeron**, provided insights into the creation of the ANC capability in the AirPods 4. She disclosed that the concept of achieving ANC without ear tips emerged during a demonstration at one of Apple’s acoustic labs in 2021. Bergeron and **AirPods marketing director Eric Treski** were quickly struck by the promise of this innovation.
“We were just amazed,” Bergeron reminisced. “We thought, ‘We surely have something worthwhile here, we must pursue this and bring it to fruition.’”
Implementing efficient ANC without ear tips demanded extensive **acoustic and computational research**. Bergeron explained that the absence of ear tips complicates the noise-cancelling mechanism, as the earbuds can’t depend on a reliable physical seal to eliminate sounds. Instead, the AirPods 4 leverage sophisticated algorithms to address the void left by the lack of a seal, rendering the ANC feature even more computationally intensive than that of the **AirPods Pro**.
### The Importance of the H2 Chip
The **H2 audio chip** is vital for enabling the ANC functionality in AirPods 4. Eric Treski explained that the H2 chip empowers the earbuds to regulate ANC quality by perpetually examining ambient noise via built-in microphones. The chip processes this information in real-time to mitigate as much extraneous sound as attainable.
“It’s exceedingly challenging to deliver exceptional ANC quality in a product without ear tips,” Treski remarked. “The capabilities of the H2 make this possible, so we are leveraging the H2 chip significantly to adjust ANC quality and monitor environmental noise through the mics to ensure maximum cancellation.”
While the ANC of the AirPods 4 is remarkable, Apple continues to suggest the **AirPods Pro 2** for users in search of the utmost effective noise cancellation. The **AirPods Pro 2** utilize ear tips, which provide a more secure fit and seal, resulting in enhanced ANC efficiency.
## Design and Features
Both variations of the AirPods 4 boast an **enhanced design** that refines the accomplishments of earlier AirPods iterations. The earbuds are lightweight, comfortable, and exhibit a stylish, minimalist look that Apple enthusiasts have come to cherish.
The **ANC-enabled model** includes a **wireless charging case** that integrates built-in speakers. This feature allows users to locate their case via Apple’s **Find My** app, as the case can emit sound, aiding users in locating it if lost.
Conversely, the **non-ANC model** does not feature these extra functions but still benefits from the **H2 chip** and the refined design, rendering it a more cost-effective choice for users who do not prioritize noise cancellation or wireless charging.
## Battery Life and Performance
One aspect in which the AirPods 4 has faced some critique is **battery life**. While the ANC functionality is noteworthy, it does result in diminished battery performance. Early reviews have indicated that the battery life of the ANC-enabled model falls short compared to previous AirPods generations, particularly with ANC engaged. Nonetheless, this trade-off is typical in wireless earbuds that include advanced noise-cancellation capabilities.
## Conclusion
The **Apple AirPods 4** represent a substantial advancement
