There’s nothing like a good beat to get your heart rate going in the gym… and now you can measure it with the Nike PHYSICAL+ headphones! Rather than wear a fitness band on your wrist, this sporty, sweat-proof headset features integrated motion and health sensors to record and transmit biometrics and performance data in real time to your smartphone. Better yet, when you aren’t wearing them on your ears, the ear units detach, connect to you device wirelessly via Bluetooth, and act as a portable speaker! Designer:
