The headset supports natural voice commands, allowing for hands-free control. Simply say "Hey Cardo" followed by your command. This feature enables you to manage calls, music, and intercom functions without pressing buttons.
While generally reliable, some users may find that voice commands require repetition. Ensure clear pronunciation and minimal background noise for optimal performance.
