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.

RxEars Rxi

The RxEars Rxi is a budget-priced prescription hearing aid in an invisible-in-ear style, earning an A grade with a SoundScore of 4.1/5 in our lab testing. At $499, it ranks #24 of 39 prescription hearing aids tested, placing it in the top 59% of its category. This device demonstrates notable strengths in speech understanding in quiet environments, scoring 4.3/5—a strong result that sits 0.89 points above the category average of 3.40/5. Feedback handling is excellent at 4.7/5, providing stable performance during movement without the whistling that can plague some hearing aids. Speech in noise performance is mixed at 2.1/5, essentially matching the category average. The RxEars Rxi has significant limitations to consider. Own-voice comfort scores low at 1.6/5, falling 1.10 points below the category average—users may notice their own voice sounds unnatural or boomy. Music streaming is not supported, scoring 0.0/5, which is 2.76 points below the category average. This device uses disposable batteries rather than rechargeables. The RxEars Rxi is best suited for users who prioritize discreet cosmetics and clear speech understanding in quieter settings, and who don't need music streaming capabilities. Those sensitive to own-voice quality or who frequently listen to streamed audio should explore alternatives.
