HearingAssist Micro vs Phonak Audeo R Infinio 90

The HearingAssist Micro is a premium amplifier in the invisible-in-ear style, priced at $698. In HearAdvisor's lab testing, it earned a B grade with a SoundScore of 3.5/5, ranking #3 among 8 tested amplification products and placing in the top 25% of its category. This device demonstrates a clear strength in speech clarity for quiet environments, scoring 3.5/5—a solid result that sits 1.35 points above the category average of 2.11/5. Feedback handling is also strong at 4.0/5, providing stable performance during typical use. Own-voice comfort lands at 2.8/5, which is above the category average by 0.16 points, though still mixed in absolute terms. However, the Micro shows notable limitations in more challenging listening situations. Speech in noise scored just 1.1/5, falling 0.31 points below the category average—a meaningful weakness for users who frequently encounter background noise. Music streaming is where this device struggles most significantly, scoring 0.0/5, which is 1.16 points below the already-low category average. The HearingAssist Micro is best suited for listeners who primarily need amplification for face-to-face conversations in quiet settings and prioritize a discreet, nearly invisible form factor. Those who rely on phone streaming for music or podcasts, or who need robust performance in noisy environments, should consider alternatives. Within its price range, the Sennheiser Conversation Clear Plus offers notably higher overall performance at a similar investment.

In our lab testing, it earned an A grade with a SoundScore of 4.4/5, ranking #18 among 39 prescription hearing aids tested. Speech clarity is a standout strength in our testing.

Speech in noise performance is more mixed at 2.5/5—above the category average by 0.37 points, but only moderate in absolute terms. This pattern suggests the Infinio 90 excels in calmer listening environments while offering incremental benefits in challenging noise. Streaming music quality impressed at 4.0/5, a strong score that lands 1.24 points above category average. Feedback handling scored 4.2/5, which is strong in absolute terms though 0.52 points below the category average. Own-voice comfort was mixed at 2.2/5, falling 0.50 points below average—something to discuss with your hearing care provider if natural voice quality is a priority. The Infinio 90 competes in a crowded premium segment. At this price point, alternatives like the Phonak Sphere Infinio (4.98/5) and Oticon Intent (4.83/5) achieved higher overall scores in our testing. Buyers seeking Phonak's ecosystem and strong speech-in-quiet performance may find the Infinio 90 appealing, though those prioritizing noise performance or own-voice comfort should compare options carefully with their provider.
