Many headsets and headphones with manual volume controls let you change Milo’s volume from those controls. You can still use Milo’s own volume buttons as well — they stay in sync to give you flexibility. Similarly, on many headsets with a manual mic mute button, you can mute or unmute using either the headset’s button or the Milo button.
Not all accessories synchronize well, however. We recommend testing this on your favorite headset or headphones before your first Milo activity.
We have some headsets and headphones we ourselves use and test with extensively. You can read more here: Third Party Accessories
NOTE: Milo still uses its built-in microphones even when you use a headset that has its own mic. In Advanced Settings, you can choose to include or exclude audio from a connected external headset mic.
