The Mini still has a microphone-off slider switch on the side, so you can disable the microphone anytime. The volume controls are capacitive touch buttons, but they’re now located on the sides of the device — with accompanying embedded LEDs to indicate their placements. When you touch each side of the device, the volume goes up or down.
Manually controlling the volume isn’t all that necessary with the Nest Mini though, as the device automatically adjusts its volume based on the background noise in the room. We noticed when there was a lot of conversation or when TV was playing, the Nest Mini would produce louder music and responses than when the room was completely quiet
