Answer calls with any Bluetooth device up to 33' away using this comfortable, lightweight headset. Its noise-canceling microphone filters out ambient noise around you to ensure your voice will be heard for clear, more natural conversations. Plus, it automatically cancels echoes for crisp calls without any distractions. Advanced hearing protection eliminates sudden spikes in volume to protect your ears during any call. A powerful, 300mAh battery provides 21 hours of talk time and 500 hours of standby time on a single charge to let you appreciate the crystal-clear sound for longer. Volume and mute controls allow you to quickly adjust the settings directly from the headset instead of requiring you to keep your device nearby. Visual indicators conveniently display the call status, pairing status and more to ensure you're always in complete control.
