Cearvol Diamond X1

The Cearvol Diamond X1 is a budget-priced OTC hearing aid available for $199, earning a B grade with a SoundScore of 3.7/5 in our lab testing. This visible-in-ear style device ranks #30 among 65 OTC hearing aids tested, placing it in the top 45% of its category. The Diamond X1 delivers a mixed performance profile with one notable strength: music streaming. With a score of 4.1/5, it performs 2.18 points above the category average—a substantial margin that makes it appealing for users who value audio entertainment through their hearing aids. Feedback handling is excellent at 4.5/5, providing stable performance during typical daily movements. Both iPhone and Android streaming are supported with rechargeable batteries for convenience. Speech performance presents a more modest picture. Speech in quiet scores 2.8/5, which is above the category average but only mixed in absolute terms. Speech in noise measures 1.7/5—above the category average of 1.48/5, though still low overall. Own-voice comfort is a weakness at 1.7/5, falling 0.81 points below the category average, which may cause your own voice to sound unnatural or boomy. The Diamond X1 is best suited for budget-conscious consumers who prioritize music and media streaming over maximum speech clarity. Those seeking stronger speech performance in challenging listening environments may want to consider higher-scoring alternatives in this price range, such as the Elehear Beyond or Apple AirPods Pro 2.

Cearvol Wave

The Cearvol Wave is a budget-priced OTC hearing aid with a visible in-ear style, earning a B grade with a SoundScore of 3.9/5 in our lab testing. At $397, it ranks #22 among 65 OTC hearing aids tested, placing it in the top 32% of its category. The Wave's standout performance is in music streaming, where it scores a strong 4.1/5—a full 2.18 points above the OTC category average. This makes it an unusually capable choice for users who prioritize audio entertainment alongside speech amplification. Speech performance is solid in quiet environments at 3.1/5, sitting 0.36 points above the category average. Speech in noise presents a more mixed picture: while the 2.0/5 score exceeds the category average by 0.56 points, it remains modest in absolute terms—typical of OTC devices without advanced noise management. Own-voice comfort scores 2.1/5, falling 0.41 points below average, which may be noticeable during extended wear. Feedback handling is solid at 3.8/5, though 0.74 points below the category average. The Cearvol Wave is best suited for budget-conscious consumers who want capable music streaming and adequate speech clarity in quieter settings. Those frequently in noisy environments or sensitive to own-voice quality may want to consider alternatives with stronger performance in those areas.
