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.
Choice
Oticon More
The Oticon More is a premium prescription behind-the-ear hearing aid that earns an A grade with a SoundScore of 4.6/5 in our lab testing, placing it in the top 23% of the 39 prescription hearing aids we've evaluated. Currently available at $4,598, this 2021 release has earned our Expert's Choice Award in both 2023 and 2024. In our testing, the Oticon More demonstrates strong speech clarity performance. Speech in quiet scores 4.0/5, which is 0.65 points above the category average—a meaningful advantage for everyday conversation. Speech in noise measures 2.7/5, which is 0.60 points above the category average, though the absolute score reflects the inherent challenge all hearing aids face in noisy environments. Own-voice comfort is solid at 3.1/5, sitting 0.40 points above average. The device does show one notable weakness: feedback handling scores 3.5/5, which is 1.22 points below the category average of 4.72/5. While this is still a solid score in absolute terms, competing devices in this price range generally perform better in this area. Music streaming is solid at 3.0/5, slightly above the category average. The Oticon More offers flexibility with both rechargeable and disposable battery options, plus streaming compatibility with both iPhone and Android devices including hands-free calling. For those considering alternatives, newer models like the Oticon Intent and Oticon Real score higher in our testing at similar price points. The Oticon More remains a capable choice for listeners who prioritize speech clarity and want a well-established platform with proven performance.
