Thinking of buying some new earphones this year? They might just monitor your movement even if you dont want them to. Wristband wearables may only just be hitting the mainstream, but manufacturers like Misfit are already unveiling the next stage of on-body tech and its all about the ears. Future kit could take your temperature and tap into your neuro-activity, but most of todays hearables (as theyve been dubbed) are still quite simple. Misfits Specter is a set of Bluetooth phones with a battery box that clips to your collar and doubles up as a step-tracking, sleep-monitoring machine. Like a wrist-based tracker, itll also sync stats with your smartphone as well as allowing you to control compatible Internet of Things objects in your house via the Misfit Link app. That said, Bragis wireless Dash buds are significantly smarter, packing in-ear biometrics, live activity feedback and gesture controls for a canal-filling smart experience. Simplistic or not, with connected chips shrinking you could soon be seeing activity tracking tech in every pair of phones. Rumours abound as to Apple's possible removal of the headphone jack on the iPhone 7 and a pair of hearable smart phones could well be the replacement.
