Apple adds a skin detector sensor to the Airpods (2nd Generation) instead of the optical sensor of old Airpods. Due to the new sensor the music can play and pause automatically and works much better on the newer Airpods than before. The AirPods 2nd Gen are powered by Apple's H1 headphone chip, which enhances the audio quality of the AirPods 2. In the ever-evolving world of technology, Apple continues to lead the way with advanced products that seamlessly integrate into our lives. The Airpods 2nd generation can adjust the audio output to the unique shape of the listener's ear, providing a more individualized and optimized listening experience. The chip also helps to reduce reaction time, improving the synchronization between audio and video, making it ideal for watching movies, and videos, and playing games.
