CearvolSoundScore 3.7Grade B

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.

ReSound OMNIA RIE

The ReSound OMNIA RIE is a premium prescription behind-the-ear hearing aid released in 2022, currently available at $4,498. In HearAdvisor's lab testing, it earns a B grade with a SoundScore of 3.9/5, ranking #31 of 39 devices in the prescription hearing aid category. This device shows notable strengths in speech clarity for quiet environments, scoring 3.7/5—a solid result that sits 0.34 points above the category average. Own-voice comfort also performs above average at 3.0/5, which may appeal to users who find their own voice bothersome in other devices. Feedback handling is strong in absolute terms at 4.1/5, though it falls 0.62 points below the category average of 4.72/5. The OMNIA RIE's most significant limitation is speech in noise performance, scoring just 1.0/5—a low result that trails the category average by 1.11 points. For users who frequently encounter challenging listening environments like restaurants or group conversations, this represents a meaningful gap compared to alternatives. Music streaming scores a mixed 2.7/5, essentially matching the category average. The device offers flexible power options with both rechargeable and disposable batteries, plus streaming compatibility with iPhone and Android devices including hands-free functionality. However, at this premium price point, several competitors deliver stronger overall performance, including options from Phonak, Oticon, and Widex. The OMNIA RIE may suit users who prioritize quiet-environment clarity and own-voice comfort over noise-handling capabilities.
