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.

Elehear Alpha
The Elehear Alpha is a budget-priced OTC hearing aid that earned a B grade with a SoundScore of 3.4/5 in HearAdvisor's lab testing. At $299, this behind-the-ear device sits in the lower price tier of the OTC category and delivers a performance profile with notable strengths and weaknesses. The Alpha's standout feature is its music streaming quality, scoring a strong 4.2/5—a full 2.28 points above the OTC category average. This makes it an unusually capable choice for users who prioritize audio entertainment alongside hearing assistance. Feedback handling is also excellent at 5.0/5, meaning you're unlikely to experience whistling or squealing during normal use. However, speech clarity presents challenges. Speech in quiet scores a mixed 2.1/5, falling 0.73 points below the category average, while speech in noise is low at 1.0/5, sitting 0.48 points below average. Own-voice comfort is particularly weak at 0.7/5, measuring 1.81 points below the category average—users may notice their own voice sounds unnatural or boomy. Within the same price range, several alternatives offer stronger overall performance, including the Elehear Beyond (4.36/5), Apple AirPods Pro 2 (4.06/5), and Zepp Clarity Omni (3.88/5). The Alpha may appeal to budget-conscious users who primarily want reliable music streaming and stable feedback performance, but those prioritizing speech understanding should consider higher-scoring options.
