Sometimes, your AirPods will keep on chirping even after being plugged in due to power fluctuations, interruptions to the electricity flowing into the device and other battery issues. Another possible reason for your AirPods chirping is connectivity issues with their paired device. If you've switched off Bluetooth on your iPhone, for instance, you'll most likely hear your AirPods make some noise. If you have your AirPods out and accidentally rub them together, you may hear them make a sound, as well.
