Concentration2024
The tiny precision driver at the heart of every hearing aid — the balanced-armature receiver that actually produces the sound — comes, with very few exceptions, from two companies: Sonion and Knowles. The same duopoly supplies the BA receivers in premium in-ear monitors and high-end earbuds. So the entire hearing-aid industry — a critical medical-device category for tens of millions of people, served by a few brands like Sonova/Phonak, Demant/Oticon, WS Audiology, GN and Starkey — depends on a two-supplier micro-acoustics market for its core component, and so does the high end of personal audio. Sonion, Danish, is one of those two. It's a striking concentration: a medical function essential to hearing and an audiophile product feature both rest on the same pair of specialist transducer makers, with no easy third source if either falters.

Sonion's components straddle medicine and consumer audio: the same balanced-armature and MEMS-microphone technologies serve hearing aids (regulated medical devices) and earphones and hearables (consumer electronics). As "hearables" blur the line — earbuds that also do hearing-assistance, and over-the-counter hearing aids now legal in the US — the two markets are converging onto the same component base. So a micro-acoustics maker sits exactly at the medical-consumer boundary, and the OTC-hearing-aid and hearing-earbud trend funnels even more demand onto the Sonion/Knowles duopoly. The component that lets a hearing aid restore hearing is the same one that gives an audiophile earphone its detail — a dual-use that is becoming a single converging market resting on a concentrated supply base, which makes these two quiet Danish-rooted firms unexpectedly central to both healthcare and consumer tech.
