Question: what is the size difference between airpods 1 and 2?
Answer: AirPods 2 uses Apple's new H1 chip, whereas the original has a W1 chip. Both these allow the AirPods to pair seamlessly with Apple devices, but Apple claims AirPods 2 can connect up to 1.5 times faster, provide a more stable wireless connection, and switch between active devices up to twice as fast.
