How to adjust various sound volumes on Apple Watch
There are at least three categories of Apple Watch sound where you can adjust volume.
- For Siri voice including workout feedback it's Watch Settings, Siri, Siri Responses, go to Voice Volume - Speaker and adjust slider to required level by tapping, or tap slider and rotate digital crown. Siri volume can also be adjusted in iPhone, Watch app, My Watch tab, Siri, Siri Responses.
- For volume of caller's voice on a call using the watch, rotate the crown during a live call. No other way of doing it.
- For most other volume including notifications and alarms use Watch Settings, Sounds & Haptics and adjust the slider by tapping, or tap slider and rotate digital crown. Notification volume can also be adjusted in iPhone, Watch app, My Watch tab, Sounds & Haptics.
