The Dash

3 in 1 wireless, smart earphones


The Dash has been described as “Europe's most ambitious consumer hardware product”. It is a set of smart and wireless earbuds that, as people would expect, offer a high-quality audio experience. But it also uses miniature components embedded within the ear pieces to provide the same kind of activity and performance data that you would usually extract from a larger device.

Just like some of the health and fitness applications people download to their smartphones, the Dash will provide all the information a user needs to get the most out of their run, cycle or swim. A range of sensors within the Dash monitor steps, duration and heart rate and over time, the inventors’ aim is to gather even more sophisticated user data such as oxygen saturation levels, calories burned and body temperature, as well as information on their environment.

Digital MEMS (microelectromechanical systems) microphones capture external sounds and an ear bone microphone picks up mechanical vibration generated by a person’s voice to allow the Dash to be used as a Bluetooth® headset. Ambient sound can be channeled into the earphones if users need to stay in tune with their surroundings, or it can be blocked with the noise cancelling feature. If the device is connected to a smartphone, existing music playlists can be accessed via Bluetooth® low energy, or users can tap into the device’s 4GB of flash memory.

The Dash utilizes NXP’s Kenetis K24 microcontroller based on the ARM® Cortex®-M4 CPU. The earphones contain a lithium polymer battery that lasts for up to three hour and can be recharged in less than two hours using the innovative charging case that comes with the device.
