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

Linner Nova Earbud
The Linner Nova Earbud is a budget-priced OTC hearing aid that earns a B grade with a SoundScore of 3.4/5 in HearAdvisor lab testing. At $299, it ranks #39 of 65 OTC hearing aids tested, placing it in the top 58% of its category. This device shows a distinctive performance profile with clear strengths and weaknesses. Music streaming is a standout at 4.5/5—an excellent score that sits 2.58 points above the category average. Feedback handling is equally impressive at 5.0/5, meaning users can expect stable performance without whistling during normal wear. These metrics suggest the Linner Nova excels as a streaming-capable earbud-style device. However, speech clarity metrics fall below category averages. Speech in quiet scores 2.1/5, which is 0.71 points below average and reflects mixed absolute performance. Speech in noise is low at 1.3/5, trailing the average by 0.19 points. Own-voice comfort is particularly challenged at 0.5/5—a low score that sits 2.01 points below the category average, meaning users may notice their own voice sounds unnatural or boomy. The Linner Nova Earbud may appeal to buyers who prioritize streaming audio quality and stable feedback-free wear over maximum speech benefit. Those seeking stronger speech clarity should consider alternatives in this price range like the Elehear Beyond (4.34/5) or Apple AirPods Pro 2 (4.04/5), which score higher overall.

Lucid Enrich Pro
The Lucid Enrich Pro is a budget-priced OTC hearing aid available for $200, earning a B grade with a SoundScore of 3.7/5 in our lab testing. This visible-in-ear style device ranks #31 of 65 OTC hearing aids tested, placing it in the top 46% of its category. The Enrich Pro's standout strength is speech understanding in quiet environments, scoring 3.8/5—nearly a full point above the OTC category average. This solid performance in everyday conversation settings is notable for a device at this price point. Speech in noise measures 1.7/5, which is above the category average but low in absolute terms, indicating limited benefit in challenging acoustic environments like restaurants or group gatherings. Feedback handling is strong at 4.0/5, though slightly below the category average of 4.54/5. Own-voice comfort scores 2.0/5, falling below average and suggesting some users may notice their own voice sounds unnatural. Music streaming is not supported on this device, scoring 0.0/5. The Enrich Pro uses disposable batteries rather than rechargeables. This budget OTC option is best suited for individuals primarily seeking help with face-to-face conversations in quieter settings who don't require streaming capabilities. Buyers prioritizing music streaming or challenging noise environments may want to consider alternatives like the higher-scoring Elehear Beyond or Apple AirPods Pro 2 in this price range.
