Safety and the ability to communicate with others are important. In addition to being earphones, the Dash will double as a Bluetooth Headset delivering clear voice quality through the embedded ear bone microphone. The ear bone microphone is not sensitive to background noise, since it picks up mechanical vibration generated by your voice from the ear bone. Even though The Dash provides impressive noise isolation, the wearer can choose to channel ambient sound into the headphone with the transparent audio feature. A swipe on the capacitive touch surface of The Dash will enable or disable ambient sound to pass through.
