CearvolSoundGrade B

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.

Jabra Enhance Select 500

The Jabra Enhance Select 500 is a premium behind-the-ear OTC hearing aid priced at $1,995 that earns an A grade with a SoundScore of 4.2/5 in our lab testing. Ranking #13 of 65 OTC hearing aids tested, it places in the top 18% of its category. This 2024 release demonstrates strong speech-in-quiet performance, scoring 4.3/5—a full 1.50 points above the OTC category average. Speech-in-noise scores 1.8/5, which is above the category average by 0.31 points but remains low in absolute terms, reflecting a common challenge across OTC devices. Feedback handling is excellent at 4.6/5, slightly above the already-high category average. Music streaming scores 2.9/5, which is 0.98 points above the category average but only mixed in absolute terms—adequate for casual listening but not audiophile-quality. Own-voice comfort at 2.2/5 falls 0.31 points below the category average, which may be noticeable for users sensitive to how their voice sounds. The Enhance Select 500 supports iPhone and Android streaming, hands-free calling, and uses rechargeable batteries. It's a solid choice for those prioritizing clear speech in quieter environments and reliable feedback control. However, buyers seeking better value might consider the Jabra Enhance Select 300 or Lucid Engage, which offer similar sound performance at lower price points. This model has earned HearAdvisor's Expert's Choice Award in both 2023 and 2024.
