The SoundLink Max has no microphone at all, which Bose states in its specifications, so it cannot pick up your voice for calls or a built-in assistant. Anyone who expects speakerphone use will hear the person on the phone through the speaker while their own voice goes through the phone's mic. The Shortcut button can wake the phone's voice assistant instead. Bose also warns that some calling apps use the Headset Profile, so their audio may not play through a Bluetooth speaker.

ReversibleBose's specification sheet lists the SoundLink Max as No Microphone, so no setting can enable one.
Use the phone's mic
ReversibleDuring a call, hold or place the phone so its own microphone can hear you while the speaker plays the caller's voice.
Set the shortcut
ReversibleIn the Bose app tap the speaker, choose Shortcut and pick your mobile device's voice assistant, then press Shortcut once to start it.
Try another app
ReversibleSome calling apps do not use the Hands-Free Profile the speaker supports, so switch to the phone's standard call function or another app.
Reset
ReversibleUnplug the cable and hold Power up to 30 seconds if the button behavior seems wrong, then power on and test again.
Model-specific
What is true of this model and not of its siblings
- Shortcut light
- Slow white blinking means speakers are linking and solid white means they are linked. The Shortcut button can start linking, wake the phone's voice assistant or resume Spotify.
Stop boundary
When this stops being a self-service repair
- !If you need hands-free calling from a speaker, choose a Bose speaker whose specifications list a microphone
- !If the speaker plays audio but ignores buttons, reset it and contact Bose if that fails
