Cearvol Diamond X1 vs GoHearing Ultra
Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

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.

GoHearing Ultra
The GoHearing Ultra is a budget-priced behind-the-ear OTC hearing aid that earns a B grade with a SoundScore of 3.1/5 in our lab testing. At $499, it sits in the most affordable price tier of the OTC market, though its overall sound performance ranks #58 of 65 devices in its category. In our testing, the Ultra shows a distinctive performance profile with significant strengths and weaknesses. Feedback handling is excellent at 5.0/5, scoring 0.46 points above the category average—users can expect stable operation without whistling during typical wear. Music streaming quality is also a genuine strength at 3.6/5, performing 1.68 points above average, making it notably better for phone audio than most OTC devices. However, speech clarity scores reveal meaningful limitations. Speech in quiet environments measured just 1.0/5, which is 1.79 points below the category average and low in absolute terms. Speech in noise similarly scored 1.0/5, falling 0.48 points below average. Own-voice comfort rated 1.9/5, also below the category norm. These results suggest the Ultra may struggle to deliver the speech audibility improvements that many users prioritize. The GoHearing Ultra may suit budget-conscious consumers who primarily want reliable streaming audio and feedback-free operation, and who have modest expectations for speech enhancement. However, several competitors in the same price range—including the Elehear Beyond and Apple AirPods Pro 2—deliver substantially stronger overall sound performance. Users prioritizing speech clarity should consider these alternatives despite similar pricing.
