First look at Kuai Headphones
Those of you racing Escape from Alcatraz or Ironman 70.3 Boulder may have noticed, or tested, a prototype device developed by Kuaiwear, Kuai headphones. Triathlete and CEO Carlos Rider developed this device that can measure and track heart rate, VO2 max, cadence, calories, distance, speed and pace on land and water, amongst other features. This device can work alone, or with other devices using Bluetooth or Ant+.
A Kickstarter effort for this product is ongoing. What makes it more interesting than the items on Kickstarter that never see fruition, the research and development is already completed. The Kickstarter launch is for manufacturing costs only.
The Kickstarter campaign appears, as of this writing, almost fully funded. Slowtwitch plans to test this product in November, 2015.
