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

Cearvol Diamond X1
The Cearvol Diamond X1 is a budget-priced OTC hearing aid available for $199, earning a B grade with a SoundScore of 3.7/5 in our lab testing. This visible-in-ear style device ranks #30 among 65 OTC hearing aids tested, placing it in the top 45% of its category. The Diamond X1 delivers a mixed performance profile with one notable strength: music streaming. With a score of 4.1/5, it performs 2.18 points above the category average—a substantial margin that makes it appealing for users who value audio entertainment through their hearing aids. Feedback handling is excellent at 4.5/5, providing stable performance during typical daily movements. Both iPhone and Android streaming are supported with rechargeable batteries for convenience. Speech performance presents a more modest picture. Speech in quiet scores 2.8/5, which is above the category average but only mixed in absolute terms. Speech in noise measures 1.7/5—above the category average of 1.48/5, though still low overall. Own-voice comfort is a weakness at 1.7/5, falling 0.81 points below the category average, which may cause your own voice to sound unnatural or boomy. The Diamond X1 is best suited for budget-conscious consumers who prioritize music and media streaming over maximum speech clarity. Those seeking stronger speech performance in challenging listening environments may want to consider higher-scoring alternatives in this price range, such as the Elehear Beyond or Apple AirPods Pro 2.

Lucid Enrich Pro
The Lucid Enrich Pro is a budget-priced OTC hearing aid that earns a B grade with a SoundScore of 3.7/5 in our lab testing. At $200, it ranks #31 of 65 OTC hearing aids tested, placing it in the top 46% of the category. This visible-in-ear device delivers its strongest performance in speech-in-quiet scenarios, scoring 3.8/5—a solid result that sits 0.98 points above the OTC category average. Feedback handling is also strong at 4.0/5 in absolute terms, though it falls 0.54 points below the category average. Speech-in-noise performance scores 1.7/5, which is above the category average by 0.19 points but remains low in absolute terms, suggesting limited benefit in challenging listening environments. Key limitations include own-voice comfort, which scores a mixed 2.0/5 (0.51 points below category average), and music streaming, which scores 0.0/5—significantly below the category average of 1.92/5. The device uses disposable batteries rather than rechargeables. The Lucid Enrich Pro may suit budget-conscious consumers who primarily need help hearing speech in quieter settings and don't require music streaming functionality. Those who frequently encounter noisy environments or value streaming audio should consider alternatives in this price range, such as the higher-scoring Elehear Beyond or Apple AirPods Pro 2.
