*I find it quite funny how I have greater control over the noise control on the AirPods on non-Apple devices than on Apple devices, becuase on Apple Devices, there are just 3 options More Noise (0), Midway through (50), and Less Noise (100), but here I can set any value between 0 and 100.*

## Configure Stem Long Press
I have noted all the packets sent to configure what the press and hold of the steam should do. The packets sent are specific to the current state. And are probably overwritten everytime the AirPods are connected to a new (apple) device that is not synced with icloud (i think)... So, for non-Apple device too, the configuration needs to be stored and overwritten everytime the AirPods are connected to the device. That is the only way to keep the configuration.
