LG launched two wearable products at CES: the Lifeband Touch activity tracker (above) and the Heart Rate Earphones. Both connect to smartphones and communicate with LG's fitness app (as well as third-party apps) and are designed to work together. The Lifeband measures distance, speed, and calories burned while the earphones measure blood flow to collect data on heart rate and oxygen consumption.
