Most people like to listen to a bit of music while running. The Kuaifit are the headphones that are made for the runner’s lifestyle. Not just music devices though, these bad boys act as and activity tracker and coach rolled into one device.

This is an interesting take on headphones, activity trackers and fitness coaching. These headphones don’t require your smartphone as you can upload your music directly into the device. You can also save money on trainer because you can use the coaching provided with the headphones (basic trainings are provided, for more you must pay an additional fee). These also act as your activity tracker and heart rate monitor limiting the amount of devices you need.

That is the really cool thing about these. It’s an all in one devices that’s fairly easy to use. On the down side though, they don’t fit that well and the battery and music quality could be better than it is. Also, if you’re not in need of coaching to reach your goals, this has limited appeal.
