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.

The Starkey Edge AI RIC is a premium prescription hearing aid released in 2024, priced at $5,000. In HearAdvisor's lab testing, it earned an A grade with a SoundScore of 4.4/5, ranking #18 among 36 prescription hearing aids tested. This behind-the-ear device demonstrates particular strength in speech clarity, scoring 4.1/5 for speech in quiet—0.76 points above the category average. Music streaming is a standout feature at 3.8/5, a solid score that sits 1.16 points above the prescription hearing aid average. Speech in noise performance scores 2.6/5, which is above the category average by 0.69 points but remains mixed in absolute terms, reflecting the inherent challenge of understanding speech in noisy environments. Feedback handling is excellent at 4.7/5, essentially matching the category average. Own-voice comfort scores 2.8/5, slightly above average but mixed overall—a common trade-off in hearing aids optimized for audibility. The device responded well to professional fitting, with the normalized Tuned Score reaching 4.7/5 compared to 4.2/5 at initial fit, a meaningful 0.5-point improvement. The Edge AI RIC earned HearAdvisor's 2024 Expert's Choice Award and offers iPhone and Android streaming with hands-free capability. At its premium price point, buyers should note that several competitors in the same price range achieve higher overall scores, including the Phonak Sphere Infinio (5.0/5) and Oticon Intent (4.85/5). This device may appeal to users who prioritize Starkey's ecosystem, strong speech-in-quiet performance, and above-average music streaming quality.
