Transform the way you care through in-ear biometric technology. 

Our EarMetrics®️ Vision

Through EarMetrics®, our unique, end-to-end in-ear and biometrics technology, we want to transform how people and practitioners access or provide healthcare. Built into medical devices – including medical-grade monitors and handhelds – wearables, and hearing aids, EarMetrics® aims to record synchronised, multi-biometric real-world data within a responsible, trusted and clinical-grade cloud architecture. As an interoperable solution that could harness high-quality and racially inclusive data, EarMetrics® also has the potential to enhance healthcare with machine learning insights. There’s an incredible opportunity ahead, and we plan to seize it.

Improving data accuracy

Because EarMetrics® data is gathered from a site closer to the brain and heart, its accuracy could surpass any wearable on the market. This previously untapped data has the potential to revolutionise medical monitoring, patient interaction, healthcare and clinical research, and personal health and wellness, particularly when paired with our cloud product.

Created in collaboration with experts

EarSwitch was founded by former UK NHS doctor, Dr Nick Gompertz. The technology, that was originally developed with National Institute for Health Research (NIHR) to help people communicate, has progressed into the impactful space of health and wellbeing monitoring as EarMetrics®, with further UKRI UK Government grants support.  

Potential use cases for EarMetrics® technology 

Wearable health

EarMetrics® data can contribute directly to digital health records, enhance remote patient monitoring, and support Hospital at Home services. As such, you could help to improve healthcare outcomes by integrating EarMetrics® into wearables and hearing aids.


This could be particularly important for chronically ill and vulnerable people, but also for those at risk of digital exclusion. We want to ensure that a lack of access to online services doesn’t equate to poorer health outcomes.

EarMetrics® for hearing aid manufacturers

Gain insights into the transformative potential of EarMetrics® technology, understand how it can enhance hearing aid devices, and explore opportunities to contribute to a more inclusive and advanced future of healthcare.

Biometric data

Diet and wellness trends indicate that people are more health-conscious than ever before. With EarMetrics®, you could empower your patients or consumers with better insight into their digital biomarkers, and therefore their personal health.  

By integrating EarMetrics® into earphones or other monitoring sensors, you could also help to improve their healthcare outcomes. For instance, reliable access to patient and consumers’ digital biomarkers could enable the quick identification of declining health and the early actioning of preventative care.

Medical data

An enhanced understanding of health at both an individual and population level relies on accurate data – particularly with the move towards AI and machine learning. We hope to support this by recording data that is racially inclusive, contextualised to physical activity, and ready to use across applications from our secure cloud product. 


In GP consulting rooms and A&E triage, practitioners would be assured of the speed, reliability, and historical context of data from EarMetrics® hand-held devices, supported by EarMetrics® Cloud insights.  Racially inclusive blood oxygen readings and data that aims to be medical grade could change the way that healthcare providers work.
