Cearvol Diamond X1 vs Widex Allure RIC 440
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.

In HearAdvisor's lab testing, it earned an A grade with a SoundScore of 4.7/5, ranking #7 among 39 prescription hearing aids tested—placing it in the top 15% of its category. This device delivers excellent speech clarity in quiet environments, scoring 4.4/5—a strong result that sits 1.04 points above the category average of 3.40/5. Speech understanding in noisy settings scores 2.3/5, which is above the category average but only mixed in absolute terms. Own-voice comfort is solid at 3.0/5, sitting 0.30 points above average. The most significant limitation is feedback handling, which scores just 1.7/5—a low result that falls 3.02 points below the category average of 4.72/5. Music streaming performance is mixed at 2.7/5, essentially matching the category average. These feedback challenges may require careful management during fitting and daily use.
