Smashed earbud with ear tip, primary board, charger contact board, violently removed SoC, and partially detached lithium battery hanging out.

They're all from the same eBay seller and presumably the same factory with matching enclosures, labeling, and design techniques. Lineup of the three amplifier modules (labeled 2.4G 10W, 1250, and 915) with the heatsink planned for future use.
