This is a CLI tool for Grabbing the AirPods Battery Status

Information is collected from defaults read /Library/Preferences/com.apple.Bluetooth to grab Battery Info from a pair of connected AirPods. It will currently only grab the info for the first paired set of W1 supported headphones.

If you have multiple sets of Headphones, you can change the line that reads:

MAC_ADDR=$(grep -b2 "Minor Type: Headphones"<<<"${SYSTEM_PROFILER}"|awk '/Address/{print $3}')

To match the MAC address of heaphones you want info for:

MAC_ADDR="7c-04-d0-af-88-62"
