Music controls work well for controlling phone audio during workouts and are one of the more genuinely useful smartwatch additions.
Music controls are available and useful, with support for controlling apps like Spotify and integrated music control features.
There is no onboard music storage or local playback, so audio control depends on having a phone nearby.
