Audien Atom X vs Cearvol Diamond X1

The Audien Atom X is a budget-priced OTC hearing aid available for $389, earning a B grade with a SoundScore of 3.3/5 in our lab testing. This visible-in-ear style device ranks #54 of 65 OTC hearing aids tested, placing it in the lower portion of the category. In our testing, the Atom X showed a mixed performance profile with notable strengths and weaknesses. Feedback handling was excellent at 5.0/5, scoring 0.46 points above the category average—meaning users are unlikely to experience whistling during normal wear. Music streaming was also a highlight at 3.3/5, coming in 1.38 points above the OTC average, making it a solid choice for those who prioritize audio entertainment. However, speech clarity showed limitations. Speech in quiet scored 1.5/5, falling 1.25 points below the category average, while speech in noise measured 1.0/5, which is 0.48 points below average. These low absolute scores suggest users may find speech understanding challenging, particularly in difficult listening environments. Own voice comfort was mixed at 2.3/5, slightly below the category average. The Atom X may appeal to budget-conscious consumers who prioritize streaming quality and feedback-free wear over speech enhancement. However, several competitors in the same price range—including the Elehear Beyond (4.36/5) and Apple AirPods Pro 2 (4.06/5)—offer stronger overall performance. Shoppers focused primarily on speech clarity may want to explore alternatives.

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.
