Intel CEO Brian Krzanich unveiled the chipmakers new wearable prototypes at yesterdays keynote address. Among the reference designs was a pair of smart earbuds with biometric capabilities, designed to track the users run, record burned calories, and read their heart rate. Intel is showing of said design off at its booth at CES. The earbuds are lightweight but bulky — presumably to house all those sensors — but wont require a separate power source for a charge. Intel says that developers will also be able to develop especially for the device.
