These fitness tracker earbuds are able to do more than traditional earbuds and are designed to withstand the most intense workouts. Currently, FIIL Carat Pro earbuds are funding on Kickstarter with a goal to raise $50,000 in 40 days.

Carat Pro earbuds have heart rate monitoring and real-time audio coaching capabilities to help any level of fitness fanatic train smarter. While on the go, the Carat fitness coach gives the wearer tips using PerformTek precision biometrics technology. The dedicated Sport Button on the earbuds trigger this technology to provide incredible accuracy to ensure the wearer is working out in the right zone to meet their fitness goals. The audio coach will give the wearer feedback for heart rate, distance, steps, and duration.

“We want to go above and beyond the scope of traditional earbuds with the FIIL Carat Pro earbuds,” said FIIL president and Rock Star WangFeng. “Including Valencell’s PerformTek biometrics, we are able to create a high-tech sport earbud that no one has ever seen before. This technology is even more accurate and advanced than smartwatches and fitness trackers for wrists and has different modes, like necklace mode, that not only looks fashionable, but makes for easy access.”

To use the Carat Pro sport modes, one press of the sport button gives the wearer real time heart rate, distance, steps, and duration of the workout. Press the button twice to start a new round of exercise calculation, when finished, press the button twice again to end the workout.

Carat Pro’s patented Speed Dependent Sound Technology (SDS) gives the wearer the beats they need to finish strong. Depending on the wearer’s heart rate and speed, corresponding sound effect beats will change, pumping up when working out hard and calming down when it is time to cool down.

Be hands-free with Carat Pro’s 4G of storage and voice search functions. Users can store up to 1,000 songs in MP3, WAV, FLAC or AAC formats within the earbuds. These songs can easily be found by voice commands. The wearer can say “play Thriller by Michael Jackson” and the song will start to play. When the wearer is in Bluetooth mode, they can search for songs through streaming apps like Spotify.

Using the FIIL+ app, wearers can choose between running, yoga, biking, walking and indoor training workouts to accurately track various measurable data. Each workout setting will provide seven kinds of stats including heart rate, oxygen intake, calories burned, distance, time, speed and cadence/pace speed.

Carat Pro’s inline control lets wearers control volume, switch tracks, and take calls easily. Connecting to music streaming apps, such as Spotify and Pandora, allows Carat Pro users to easily control songs when using their phone.
