Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

HearingAssist Micro
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.

Signia Active Pro IX
The Signia Active Pro IX is a premium prescription hearing aid with a visible-in-ear design, priced at $3,199. In HearAdvisor's lab testing, it earned an A grade with a SoundScore of 4.6/5, ranking #8 among 39 prescription hearing aids tested. This device delivers strong speech clarity performance. Speech in quiet scores 4.3/5, which is +0.85 points above the category average—a notable strength for everyday conversations. Speech in noise measures 2.9/5, which is +0.74 points above the category average, though the absolute score reflects mixed performance in challenging listening environments. Own-voice comfort scores a solid 3.3/5, sitting +0.60 points above average, suggesting reasonable naturalness for wearers. Music streaming quality is mixed at 2.9/5, only slightly above the category average (+0.14 points). Feedback handling scores 3.4/5—solid in absolute terms but -1.32 points below the category average of 4.72/5, indicating this device may be more prone to feedback than typical prescription aids in our standardized tests. The Active Pro IX features rechargeable batteries and supports both iPhone and Android streaming with hands-free capability. It earned HearAdvisor's 2024 Expert's Choice Award. Buyers in this premium price tier should note that competitors like the Phonak Sphere Infinio and Oticon Intent score higher overall. Those seeking similar performance at lower cost may want to explore options like the Rexton Reach R-Li T80 at Costco.
