+## Bluetooth DID (Device Identification) Hook
+
+Turns out, if you change the manufacturerid to that of Apple, you get access to several special features!
+
+### Multi-device Connectivity
+
+Upto two devices can be simultaneously connected to AirPods, for audio and control both. Seamless connection switching. The same notification shows up on Apple device when Android takes over the AirPods as if it were an Apple device ("Move to iPhone"). Android also shows a popup when the other device takes over.
+
+### Accessibility Settings and Hearing Aid
+
+Accessibility settings like customizing transparency mode (amplification, balance, tone, conversation boost, and ambient noise reduction), and loud sound reduction can be configured.
+
+The hearing aid feature can now also be used. Currently it can only be used to adjust the settings, not actually take a hearing test because it requires much more precision. It is much better to use an already available audiogram result.
