A red 2-in-1 button easily activates Siri, Google Now, or Cortana. Whispered alerts update you on talk time, and even announce the names of incoming callers so you can simply say “Answer” or “Ignore” to calls without lifting a finger. During calls, simply press the red button to switch mute on and off easily. The headset’s dynamic mute alert tells you immediately if you’re speaking while muted. Plus, timed voice alerts continually remind you when mute is still on.
