AirPods 4th Generation

As of my knowledge cutoff in October 2023, Apple has not officially released a 4th generation of AirPods. The latest models available were:

1. AirPods 3rd Generation (released in October 2021), which feature:

   • A new design, similar to the AirPods Pro, but without the silicone tips.
   • Spatial audio with dynamic head tracking.
   • Longer battery life (up to 6 hours of listening time on a single charge).
   • Adaptive EQ for better sound quality.
   • IPX4 water resistance (sweat and water-resistant).
   • MagSafe and Lightning charging support for the charging case.

2. AirPods Pro (2nd Generation) (released in September 2022), which include:

   • Active Noise Cancellation and Adaptive Transparency.
   • Improved sound quality with a custom driver and amp.
   • H2 chip for better audio performance and battery life.
   • Longer battery life (up to 6 hours of listening time with ANC on).
   • Personalized spatial audio and dynamic head tracking.
   • Improved fit with multiple sizes of silicone ear tips.
   • IPX4 water resistance.
   • MagSafe and Lightning charging support.

There may be rumors or expectations about a potential AirPods 4th Generation, but no official details have been confirmed at the time of my last update. If you're interested in the latest news, I'd recommend checking Apple's official website or tech news sources for any new announcements.
