£75,517

752

Kuai are the world’s first multisport biometric headphones designed to be used during every type of exercise, including swimming, cycling and running. It has integrated heart rate sensor and accelerometer to calculate accurate heart rate, VO2max, distance, cadence, speed/pace and calories. Kuai are waterproof up to 3 meters and with its 8GB integrated memory, they can work autonomously or connect to phone apps. With Kuai you can listen to music, record your sport performance data, setup voice alert, create interval sessions and listen to professional training plans.

Kuai monitors your biometrics and sport performance using the most advanced, patented and clinically validated biometric sensor technology. 

   

Kuai are the first headphones ever to appear on a crowdfunding campaign that have Clinically Validated technology to measure accurate biometric data during exercise.

Peer Review Scientific Journal from Clinical Tests Publicly Funded: http://www.ncbi.nlm.nih.gov/pubmed/24743110

David Clark, Ultra-Marathoner and author of the best selling book “Out There: A Story of Ultra Recovery” run a full marathon (26.2 miles) on a treadmill during IRONMAN 70.3 Boulder in 3h 38min using Kuai prototypes to continuously and accurately measure his heart rate, speed, distance, cadence and calories.

You can see the video of David running the last minute towards the “finish line” bellow. The information displayed on the screen was sent live by Bluetooth from Kuai headphones during the entire run for display purpose.

Our initial research showed that people were extremely frustrated with the controls found in sport headphones because of the small buttons placed in inconvenient positions that made them nearly impossible to operate during exercise. Kuai was designed to offer users an easier way to operate their sport headphones:

  • Two Navigation Switches 
  • Control Like A Joysticks 
  • Right Side Control The Sport Features 
  • Left Side Control The Music And Calls 
  • Perfect For Sport 
  • Easiest Menus To Operate
  • Works Great Under Water 
  • Instant Feedback With Every Touch

Kuai is a new generation wearable that seamlessly integrates with other apps like Mapmyfitness, Runtastic, Strava, etc. via Bluetooth Smart.

Kuai saves the sports data in .FIT format, so you can easily export your workouts to virtually any sport app or software in the market.

Kuai also boasts ANT+ connectivity, which means you can link your headphones to your bike sensor and receive live voice feedback about your speed, pace, cadence and distance, while cycling.

Choose between Black, White or Limited Edition Kickstarter Green

Kuai connects to bike sensors using ANT+ technology and with our cycling package you can get sync your Kuai Headphones and Kuai Bike Sensor! This sensor is very easy to attach to any bicycle and will allow you to listen to your speed, pace, cadence and distance, through your headphones.

You can download free Kuai mobile applications for iOS & Android and desktop applications for Windows & Mac. All of your workout data synchronizes with your different devices and if you wanted to use other popular sport apps, you can connect to them with your mobile phone using Bluetooth Smart. You can also take your data from Kuai in .FIT format and export it to any other platform.

Kuai desktop app allows you to transfer music to your headset, create detailed training programs, update your headset software, and more! Kuai mobile app allows you to have full control of your workouts on the go and modify voice alerts and sport settings!

Together we can help the world train better and safer. Kuai is the world’s first and only multi-sport headphones capable of recording scientifically validated biometric data during running, swimming, cycling and more.

When you synchronize your headset with a computer or app, your biometric data gets automatically recorded anonymously (only biometric data, no personal data) in the Kuai database. As the community grows we will be able to collect more accurate biometric data from different sports. We will then share that data with the community and incorporate what we learn into the software to help everybody exercise even better and safer.

During the development stage, we conducted extensive lab testing after each design modification over groups of 20 individuals of different sizes, races and sex. These tests analyzed both fitting and biometric performance tests using Polar products and other lab equipment as benchmark. We did not stop developing and testing prototypes until we achieved the perfect fit and the most accurate data reading from the sensors.

When we move into the production phase, 100% of the sensors used inside Kuai will be checked using our custom testing unit, and 100% of finished units will tested for connectivity. Lastly, 10% of completed units will be tested in a certified water tank at 3m deep simulation.

Manufacturing Partner
Manufacturing Partner

 Kuai was born from the desire to exercise more efficiently and make every second of training count. It was created by Carlos, Oscar and Pablo, three marathoners, triathletes and Ironmen with backgrounds in Software Development, Electronic Engineering and International Business.

To complement the team, Kuai recruited the best in the business, a group of Software, Hardware and Audio Engineers with experience developing products for some of the biggest names in the industry, including Beats, Monster and Sony.

Kuai has working prototypes that accurately measure biometric data during intense exercise using clinically validated technology, unlike many other headphones featured on Kickstarter previously.

Our working prototypes already have the majority of features working, including biometric data collection, live voice coaching, BLE & ANT+ connections, music player and switch controls. We only need the last push from Kickstarter backers to develop the tooling for the molds and fine tune the software.

  • We are not raising money to research an idea. 
  • We are not raising money to develop a concept. 
  • We are not raising money to explore new technologies. 
  • We are not raising money to employ a team of experts. 
  • We are raising money to launch a product that is ready to be manufactured.

Come to see Kuai working prototypes in action at any of these events:

  • Escape from Alcatraz: June 6 & 7 – San Francisco, California, US
  • IRONMAN 70.3 Boulder: June 11, 12 & 13 – Boulder, Colorado, US
  • IRONMAN Frankfurt (EU Championship): July 2, 3, 4 & 5 – Frankfurt, Germany

Risks and challenges

Designing and manufacturing a product has its risks and challenges, however we have tried to minimize them as much as possible by setting our office in China, next to the manufacturer. We have taken care of selecting the best possible partners with reputable experience in the industry, and we have employed a very experienced team of hardware and software engineers to make sure everything can be delivered to a high standard. We have waited to launch our Kickstarter campaign until we had working prototypes that have been extensively tested in a range of ears and sports.
