CearvolSoundScore 3.7Grade B

Cearvol Diamond X1

The Cearvol Diamond X1 is a budget-priced OTC hearing aid that earned a B grade with a SoundScore of 3.7/5 in our lab testing, placing it in the top 45% of OTC devices. At $199, it represents an accessible entry point for those exploring hearing amplification. The Diamond X1's standout performance is in music streaming, scoring 4.1/5—a strong result that sits 2.18 points above the OTC category average. This makes it notably capable for users who prioritize audio entertainment through their hearing devices. Feedback handling is also excellent at 4.5/5, meaning users should experience minimal whistling during normal use. However, speech performance presents limitations. Speech in quiet scores a mixed 2.8/5, and speech in noise registers at 1.7/5. While both metrics technically sit above category averages (+0.03 and +0.22 points respectively), they remain low in absolute terms—important context for anyone prioritizing conversation clarity. Own-voice comfort is another weakness, scoring 1.7/5, which is 0.81 points below the category average and may affect how natural users sound to themselves. The Diamond X1 is best suited for budget-conscious consumers who value music streaming quality and aren't heavily reliant on challenging listening environments. Those who prioritize speech understanding in noise or natural own-voice perception may want to consider alternatives in this price range, such as the higher-scoring Elehear Beyond or Apple AirPods Pro 2.

Starkey Omega AI Hero
StarkeySoundScore 4.5Grade A

Starkey Omega AI

The Starkey Omega AI is a premium behind-the-ear prescription hearing aid released in 2025, currently available at $3,998. In HearAdvisor's lab testing, it earned an A grade with a SoundScore of 4.5/5, placing it at #13 among 39 prescription hearing aids tested. This device demonstrates notable strengths in speech performance. Speech in quiet scored 3.9/5, a solid result that sits 0.54 points above the category average. Speech in noise measured 2.9/5—above the category average by 0.75 points, though only mixed in absolute terms at under 3.0/5. Music streaming quality also performs well at 3.2/5, sitting 0.44 points above average for the category. Feedback handling is excellent at 4.6/5 in absolute terms, though it falls slightly below the category average by 0.12 points. Own-voice comfort scored 2.7/5, matching the category average exactly—a mixed result that some users may find noticeable depending on their sensitivity to occlusion effects. The Omega AI includes modern connectivity features like iPhone and Android streaming, hands-free calling capability, and rechargeable batteries. Buyers in this premium price tier should note that several competitors—including the Phonak Sphere Infinio and Oticon Intent—scored higher in our lab testing. The Starkey Omega AI is best suited for users who prioritize speech clarity in everyday listening situations and value Starkey's feature set and fitting approach.
