Overview

• 9to5Google’s video shows Pixel Buds 2a and Pixel Buds Pro 2 can charge inside each other’s cases, with a Pixel 10 recognizing the swapped case.
• Android Central reports the phone identified the case model in use while displaying charging status for both earbuds and the case.
• Swapping cases may disable certain functions, such as the Pro 2 case speaker when paired with 2a earbuds, and can trigger odd charging notifications.
• Google’s support pages do not mention or endorse using mismatched cases for these earbuds.
• The interchangeability could simplify case replacements or allow a choice between smaller size and greater battery life, a shift from earlier Pixel Buds that lacked case compatibility.
