Meet the CORE: a smart speaker system that you can wear outside while you run or do other things. It offers Bluetooth connectivity, so you can use it to answer calls. The speaker comes with a waterproof design and a battery that lasts up to 9 hours. There is also a bright LED ring that keeps you visible at night.
CORE is easy to use and does not get in your way. It is loud enough for you to easily hear what you want to listen to. More information is available on Kickstarter.
