Spec sheet

support.apple.com/en-us/1118561Maker product pagesupport.apple.com/en-us/111856Read 5 October 2026Exact 2019 AirPods 2. Reference package uses Wireless Charging Case A1938. The standard wired-only A1602 package is excluded from this file. Current shared case weight 38.2 g conflicts with the contemporary A1938 teardown specification of 40 g. Case weight now uses 40 g from the exact standalone Wireless Charging Case maker sheet 111860, which is more specific than this mixed-case row. Contradiction remains source-qualified. No standalone maker PDF datasheet found.

Bluetooth transmission bandwidth is not acoustic frequency response. Unlabelled case dimensions are not assigned to width/height/depth. Published driver diameter is 8.4 mm, with dynamic technology separately documented. Physical quantity per earbud remains unproved. The driver row preserves the proved size/type without asserting a quantity, so total driver count remains unknown.
