Why is Phonak Roger on Sphere a game changer, and for whom?
Phonak has announced Roger On Sphere, a remote microphone that uses a deep neural network (DNN) to separate speech from background noise in real time. The device is designed to help people with hearing loss follow conversations in demanding listening environments — including busy restaurants, meetings, family gatherings, and social events — where hearing aids alone may not provide sufficient support.
Is this a game changer? I would say yes; it is for two groups of patients. Read this article to learn more about Phonak Roger on Sphere.
Phonak Roger On Sphere uses a deep neural network to separate speech from background noise across all microphone modes, delivering what Phonak says is an additional 3 dB SNR benefit over its predecessor.
Do the remote microphones really help with speech in noise?
Yes, absolutely. Below is the result of 4 independent surveys by scholars who tried hearing aids for speech understanding with and without Phonak Roger remote microphones. As you can see, the improvement in speech recognition thresholds with the Phonak Roger remote microphone in all 4 studies shows a substantial improvement compared to the thresholds without the remote microphone.
AI-Driven Speech Separation at the Microphone Level
Roger On Sphere combines Phonak Sphere technology with the Roger wireless protocol. According to Phonak, the device continuously analyses the acoustic environment and applies its RogerSense OS processing engine to separate speech from noise across every microphone mode and at every noise level — without requiring manual adjustment from the user.
Compared with its predecessor, Roger On Sphere delivers an additional 3 dB signal-to-noise ratio (SNR) benefit, which the company says is equivalent to roughly 50% less noise power — allowing users to communicate in environments with twice the noise level.
Do I need to do any adjustment in Phonak Roger On Sphere for it to work better in a noisy situation?
The answer is no. The device automatically adapts its microphone mode to a range of listening situations, including meetings, lectures, online calls, restaurants, family gatherings, and car journeys, so users do not need to manually adjust settings.
What are the improvements from Phonak Roger On V3 to Phonak Roger On Sphere?
Key improvements in Phonak Roger On Sphere include:
AI-powered real-time speech-from-noise separation through RogerSense OS
Smarter adaptation across multiple listening situations
Reliable, low-latency Roger wireless transmission
An updated myRogerMic app experience and enhanced hardware design
Compatibility
Roger On Sphere is compatible with hearing aids, cochlear implants, and other hearing solutions, including Phonak Naída and Virto hearing aids and Advanced Bionics cochlear implant systems from Phonak.
What groups of patients can benefit from a Phonak Roger on Sphere remote microphone?
Here is the important part. The biggest challenge for people using hearing aids is hearing speech and enjoying the conversation in a noisy space. This can be an even bigger challenge for patients with severe to profound hearing loss, where there is a small dynamic range left in their peripheral auditory system to hear and understand the conversation.
I would highly recommend Phonak Roger On Sphere to these groups of patients:
People with severe to profound hearing loss who need to engage and enjoy conversation in noisy environments, either for leisure or work.
Patients with older models of Phonak hearing aids without AI-DNN processing, e.g. Phonak Naida, Phonak Paradise, Phonak Marvel.
Patients with ITE and ITC models of hearing aids such as Phonak Virto, which do not have AI-DNN processing.
I have a mild to moderate hearing loss. Can Phonak Roger On Sphere help with hearing speech in noise?
Absolutely. With the benefit of getting the microphone closer to the intended speech, you can improve the signal-to-noise ratio. So, a remote microphone, in my opinion, can help with any level of hearing loss, albeit the impact will be much greater for speech in noise for people with moderate to severe, severe and severe to profound hearing loss.
Can Phonak Roger on Sphere be used as a TV streamer?
Yes. Through the unit's charging docking station (provided with the unit), you can feed a sound track which can come from your TV, a stereo system or any other sound system. When the Phonak Roger On Sphere is placed on the charging dock, it receives the soundtrack and streams it to your hearing aids via Bluetooth.
I have Oticon Real hearing aids; can I use the Phonak Roger Sphere remote microphone?
You can, but it is not straightforward. If your hearing aids are any model but Phonak, then you need an intermediary device to bridge between your hearing aids and the Phonak Roger On Sphere.
For example, Oticon Real hearing aids do not have Phonak’s proprietary RogerDirect built-in streaming compatibility, but you may connect a Roger NeckLoop to the Phonak Roger On Sphere can stream audio wirelessly to a universal Roger NeckLoop, which then transmits the sound to your Oticon hearing aids via telecoil (T-coil) or Bluetooth neckloop. It is a bit messy, but it is doable.
As you can see, unlike Phonak Marvel, Paradise, Lumity, or Infinio hearing aids, Oticon or other hearing aids cannot pair natively to the Roger On V3 without hardware intermediaries.
