I've been waiting a long time for this. Wireless Bluetooth earbuds that sit inside your ear, like something out of a Jason Bourne novel, but that don't have any annoying fiddly wires or external battery packs. The Samsung IconX earbuds recharge wirelessly in their carry case, too. Paired with a heart-rate and GPS-tracking fitness watch like the new Gear Fit 2, this earbud and smartwatch combo may mean you're able to easily ditch your smartphone when you're out running or cycling for the first time ever.
