Looking to the AirPods first, there’s a very encouraging trend
occurring. They drop from 274ms to 178ms going from the first to
second generation, and the AirPods Pro take it down even further,
to 144ms. While a 130ms reduction may not seem like a lot, the
perceptual difference from this makes the AirPods Pro
tantalisingly close to seamless.
Impressive. I definitely notice the improvement with keyboard clicks turned on.
