Apple quietly makes sound quality improvements to some AirPods models

Apple has made major sound quality improvements to AirPods Pro and AirPods 3 in 2021, and it is the biggest change since 2009.

When AirPods 3 was released, it was mentioned that the new Bluetooth headphones support AAC-ELD (Advanced Audio Codec-Enhanced Low Delay), an excellent speech coder. Provides full HD voice quality.

Although Apple has only mentioned that AirPods 3 supports AAC-ELD, AirPods Pro already supports AAC-ELD. Although Apple may also add AAC-ELD support to other AirPods, it is currently confirmed that only AirPods Pro (and AirPods 3) have been added.

In the past, when users used AirPods to answer calls, AirPods would switch to Bidirectional profile, which would degrade the sound quality. The new AAC-ELD can improve sound quality and reduce latency.
