With these delicate fossils extracted, it's time to examine the brains:

Apple 343S00289 (likely Apple's new H1 chip)

Dialog Semiconductor (Formerly Adesto) AT25SL128 128 Mb serial flash memory

Apple 338S00420 (likely a low-power stereo audio codec)

T 8 36 (likely STMicroelectronics inertial sensor)

Bosch Sensortec BMA280 3-axis accelerometer (likely)

Turning our attention to the brawn, we find the familiar 93 milliwatt hour battery in each bud.
