“We are excited to expand the footprint and capabilities of our HEOS platform with our wearables and provide our customers with health tracking truly integrated with their favorite audio solutions,” said Joe Kiani, Founder and CEO of Masimo. “Now, four million devices around the world can help improve the lives of our customers by combining the joy of high-quality audio with the convenience of continuous and accurate health and wellness tracking from the comfort of their own homes.”

Masimo’s groundbreaking HEOS ecosystem platform, combined with Masimo's latest wearable health and wellness devices – such as the Masimo W1™ advanced health tracking watch, and soon the Stork™ baby monitor and Radius Tº™ continuous thermometer, select Masimo medical devices, and more – will allow users to keep track of their health and wellness, as well as share their data with loved ones and clinicians, paving the way for the next chapter in telehealth innovation and cohesive care.

This latest ecosystem innovation not only wirelessly relays health data to the HEOS-enabled home device and Masimo’s secure Health cloud for storage, analysis, reporting, and transfer, but now offers a revolutionary way to connect and interact with health technologies from the company that, among many other medical breakthroughs, invented Masimo SET^® – the primary pulse oximetry at 9 of the top 10 U.S. hospitals.¹

“The HEOS platform embodies the true essence of luxury in the modern era, where health and wellness take center stage. These new capabilities redefine what it means to live a life centered around wellness, and empower individuals to embrace self-care as an essential part of that life, transforming their lives with innovative technology and personalized insights,” Mr. Kiani continued. “We believe the health hub feature will not only differentiate Masimo audio products in the eyes of consumers worldwide, but also bring forth the next level of health and wellness by allowing connected care as consumers move around tetherless and even smartphone-less.”

Whether it’s enjoying music in the living room, kitchen, or bedroom, experiencing movie night with the family, or getting a workout in their home gyms, users all over the globe can effortlessly connect and track and record key health data from Masimo wearable monitoring devices, including pulse rate, oxygen saturation, respiration rate, hydration index, and more, using their HEOS-enabled devices. Customers will be able to access this new functionality through a cloud software update to their existing devices, which ensures a hassle-free transition to the enhanced music and health hub platform.

Some technologies and devices described may not be available or approved in every market.
