Pricing for the third-generation AirPods with a Lightning case is set at $169 in the United States, compared to $179 for the third-generation AirPods with a MagSafe case, so it seems like there is very limited value in choosing this new option.
Apple did not announce any other updates to the third-generation AirPods today, and the second-generation AirPods remain available for $129.
The new AirPods Pro feature an H2 chip for improved audio quality and up to 2x the amount of active noise cancellation, improvements to Transparency mode, a revamped charging case with Find My support and a built-in lanyard loop, Bluetooth 5.3, and more.
