Understanding speech from a distance and in noise are rated as some of the most important needs by those with hearing loss. Roger, your patient’s “third ear,” can help.
How it works
Roger isn’t just any other remote microphone. It measures the surrounding noise level and adapts the volume of the microphone accordingly. As the noise level increases or decreases, the microphone will continue to adapt, so that it can handle the dynamic nature of noisy environments. Roger microphones can provide:
- Roger technology significantly enhances speech recognition in noisy environments, achieving up to a 65% improvement in word recognition over the use of hearing aids alone7
- Compatibility with virtually any hearing aid or cochlear implant with a telecoil
Where it’s used
Anywhere that background noise, distance or the combination of the two is causing problems with communication. Roger is great for use at home, in the workplace, at restaurants or museums, social events, at school or even on the go.

Sound processing chip PRISM™
The Processing Real-time Intelligent Sound Management (PRISM) chip features double the memory and more connectivity possibilities with low power consumption.
Motion sensor
Ultra-low power motion tri-axial accelerometer supports new ease-of-use and hearing performance features. The sensor has an industry-leading balance of high performance and low power consumption.
RogerDirect™
How it works
The motion sensor tracks physical activities without additional devices and is now able to count the total number of detected steps based on the accelerometer signal.
Audéo Fit tracks heart rate, which can be viewed with the myPhonak app. The method used to track the heart rate is called “Photoplethysmography” (PPG).
On-demand heart rate, which will be calculated every four seconds, is a temporal overview of the heart rate on a daily, weekly, monthly and yearly basis, as well as the resting heart rate.
Where it’s used
During regular exercises and usual activities throughout the day, Audéo Fit and all Paradise rechargeable hearing aids track physical activities as well as the wearing time of the hearing aids. Tracking health data can encourage increased engagement with the option to set goals. 3 4
