Question: what is the difference with airpods 1 and 2?
Answer: A better phone call experience. Thanks to the H1 chip, AirPods 2 has longer support for talk time than its predecessor. Apple notes up to 50% more, though lists talk time as three hours (AirPods 1 has two hours of talk time). ... Apple also improved the audio and voice quality of the second-generation AirPods.
