Luxury headphone company Caeden is creating a stylish smart band which will monitor heartrate, steps, calories, and activity. It will give feedback designed from astronaut studies about to how accurately improve workouts. It aims to bring a style element that most smart bands in the past have been missing. It will be available in leather and silicone and for male and female styles. Early adopters can get it for just $129 (normally $199), which is priced competitively in the wearable tech market.
