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 that earned a B grade with a SoundScore of 3.7/5 in our lab testing, placing it in the top 45% of OTC devices. At $199, it represents an accessible entry point for those exploring hearing amplification. The Diamond X1's standout performance is in music streaming, scoring 4.1/5—a strong result that sits 2.18 points above the OTC category average. This makes it notably capable for users who prioritize audio entertainment through their hearing devices. Feedback handling is also excellent at 4.5/5, meaning users should experience minimal whistling during normal use. However, speech performance presents limitations. Speech in quiet scores a mixed 2.8/5, and speech in noise registers at 1.7/5. While both metrics technically sit above category averages (+0.03 and +0.22 points respectively), they remain low in absolute terms—important context for anyone prioritizing conversation clarity. Own-voice comfort is another weakness, scoring 1.7/5, which is 0.81 points below the category average and may affect how natural users sound to themselves. The Diamond X1 is best suited for budget-conscious consumers who value music streaming quality and aren't heavily reliant on challenging listening environments. Those who prioritize speech understanding in noise or natural own-voice perception may want to consider alternatives in this price range, such as the higher-scoring Elehear Beyond or Apple AirPods Pro 2.

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.
