Change function of [NC/AMBIENT] button. By default you press the NC/AMBIENT button to choose between “Ambient Sound", “Ambient Sound Control Off", and “Noise Cancelling". With a firmware update you can add Google Assistant or Alex support, and you activate the smart agent by flicking this button. The downside of this is you can only control NC/Ambient via the app once you’re in a smart assistant mode.
Automatic Power Off. You can adjust this to conserve battery power. Note that the headphones will not power off when the analogue cable is plugged in (after you turn the phones on of course).
Notification & Voice Guide. You can change the spoken language to something else in here (e.g. Brazillian, Chinese, etc). I played around with this setting, and the update to Chinese takes 7 minutes. Pass!
