HearingAssist Micro vs Sennheiser Conversation Clear Plus

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.
