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.
Choice

Elehear Beyond Pro
The Elehear Beyond Pro is a mid-priced OTC hearing aid that earns an A grade with a SoundScore of 4.2/5 in our lab testing, placing it in the top 15% of the OTC category. Priced at $631, this behind-the-ear device has received HearAdvisor's Expert's Choice Award in both 2024 and 2025. In our testing, the Beyond Pro demonstrates notable strengths in music streaming, scoring 3.8/5—a solid result that sits 1.88 points above the category average. This makes it one of the stronger options for users who prioritize audio entertainment alongside speech clarity. Speech performance is also above average, with speech in quiet scoring 3.3/5 (+0.46 vs category) and speech in noise at 2.5/5 (+1.00 vs category). While the speech-in-noise score is above the category average, it remains mixed in absolute terms at 2.5/5. Feedback handling is excellent at 5.0/5. The primary trade-off is own-voice comfort, which scores 1.2/5—a low result that falls 1.31 points below the category average. Users who are sensitive to how their own voice sounds may find this noticeable. The Beyond Pro is best suited for OTC shoppers who want strong streaming quality and solid speech performance without professional fitting. It competes in a price range that includes higher-scoring options like the Yeasound RIC800 and Sony CRE-E10, so prospective buyers may want to compare based on their priorities. Features include rechargeable batteries, iPhone and Android streaming, and hands-free capability.
