Auto-Mute Feature
The K271 MKII includes an auto-mute switch integrated into the headband. When the headphones are removed from your head, the audio signal is automatically muted. This prevents unwanted sound leakage and conserves power if connected to certain devices. The audio resumes when the headphones are placed back on your head.
