HearingAssist Micro vs Linner Nova Deluxe
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.

Linner Nova Deluxe
The Linner Nova Deluxe is a budget-priced OTC hearing aid with a visible in-ear style, earning a B grade with a SoundScore of 3.3/5 in our lab testing. At $299, it sits in the entry-level price tier for the OTC category. In our standardized testing, the Nova Deluxe showed mixed results across performance metrics. Its standout strength is excellent feedback handling, scoring a perfect 5.0/5—0.46 points above the category average. This means users can expect stable performance without whistling during typical daily activities. Speech clarity in quiet environments scored 2.8/5, matching the category average, while speech in noise measured 1.4/5, slightly below average at -0.06 points. The device has notable limitations in comfort and entertainment features. Own-voice comfort scored just 0.5/5, falling 2.01 points below the category average—users may notice their voice sounds unnatural or boomy. Music streaming scored 0.0/5, which is 1.92 points below average, indicating this device is not suitable for those who prioritize audio entertainment through their hearing aids. The Linner Nova Deluxe ranks #53 of 65 OTC hearing aids tested. Buyers seeking better overall performance in this price range may want to consider alternatives like the Elehear Beyond (4.34/5) or Apple AirPods Pro 2 (4.04/5). However, for users primarily focused on speech clarity in quieter settings who don't need streaming capabilities, the Nova Deluxe offers solid feedback stability at an accessible price point.
