Sleek design meets growth opportunities

The appearance and design of traditional hearing aids is often reported as one of the main reasons for low hearing aid adoption.¹


With Phonak Slim, we have redefined hearing aid design so that your patients can hear and be seen when and how they want to. The unique ergonomic shape of Slim is contoured to naturally nestle behind the ear – even if your patients wear glasses.


Slim provides you with a unique opportunity to address a wider range of your patients' needs early on. It can motivate patients with older hearing aids to adopt Phonak Slim, translating into greater potential to help more patients and grow your business. In addition, our marketing solutions tailored to your business needs help to generate leads.

Reach out to your sales representative to find out how we can help you grow.

Boost understanding in noise and over distance with Roger On

By combining Phonak Slim and Roger™ technology, you offer patients a truly unique solution that allows them to be themselves wherever they are. Functioning like a third ear, the new generation of Roger On**** comes with the headset mode, designed to master online calls with ease. Besides allowing your patient to hear the participants on the call, Roger On picks up the voice of the speaker and sends it to the computer, allowing the online attendees to hear your patient clearly and above the noise.
