SOUL Electronics, a global leader in consumer audio designed for the active and fitness-oriented lifestyle, announced its newest product: BLADE, the world’s first true wireless heart rate hearable earbuds with A.I. BiomechEngine. BLADE is the latest addition to SOUL’s portfolio of next-generation sports technology products centered around tracking and real-time voice coaching innovation, and these versatile true wireless earbuds are slated for a roll out on the Indiegogo crowdfunding platform in mid-February.

Building on the success of SOUL’s RUN FREE PRO BIO, which the brand launched in August 2018 to widespread industry and media acclaim, BLADE takes A.I. voice-coaching and performance & Injury risk measuring capabilities to a new level. BLADE combines SOUL’s real-time personalized A.I. voice coach and BiomechEngine™, which measures gait parameters for runners including cadence, symmetry, step length and balance, with the health benefits of a premium built-in heart rate sensor to maximize performance and help users reach new personal bests and lower injury risk in their training regimens. With all these features packed into the streamlined, ergonomic design of a Bluetooth 5.0 true wireless earbud equipped with SOUL’s signature high-quality sound, BLADE is unlike any other sport earphone currently available on the market.

“When you consider all of the incredibly advanced technology that we were able to incorporate into BLADE’s tiny, lightweight design, you realize that it’s an essential product for anyone who’s looking to improve their fitness routine,” says Angus Tsang, vice president of engineering, SOUL Electronics. “By taking the A.I. BiomechEngine™ technology we used in RUN FREE PRO BIO, which allows runners to access personalized, instantaneous data like never before, and combining it with a heart rate sensor in a true wireless design that can fit in the palm of your hand, SOUL is once again showing the world that we’re at the forefront of driving sports innovation in the consumer audio space.”

Through pairing BLADE with the SOUL FIT companion app for iOS and Android, users can view their personalized data to analyze their running form, risk of injury, monitor their heart rate and access the real-time voice coaching. SOUL FIT also provides detailed graphics and training feedback to implement for reducing injury risk and optimizing future performance. BLADE comes complete with an iPX7 weatherproof design offering added protection from sweat and water, along with a Transparent Audio Mode for added safety during outdoor workouts. BLADE also boasts up to 96 hours of total playtime, supported by its charging case equipped with USB Type-C fast charging technology.
