Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

Apple AirPods Pro 3
The Apple AirPods Pro 3 is a budget-priced OTC hearing aid available at $250, earning a B grade with a SoundScore of 3.3/5 in our lab testing. This visible-in-ear device ranks #49 of 65 OTC hearing aids tested, placing it in the top 74% of its category. The standout performance area is music streaming, scoring a strong 4.3/5—a full 2.38 points above the category average. Feedback handling is excellent at 5.0/5, meaning users can expect stable performance without whistling during normal use. However, speech performance presents a more mixed picture: speech in quiet scores 2.3/5, falling 0.53 points below the category average, while speech in noise scores 1.8/5—above the category average but low in absolute terms. Own-voice comfort is a notable weakness at 1.9/5, scoring 0.61 points below the category average, which may affect how natural your own speech sounds while wearing the devices. The product showed meaningful improvement from tuning, with the normalized score rising from 3.2/5 to 3.8/5 after adjustment. The AirPods Pro 3 is best suited for users who prioritize music streaming quality and seamless Apple ecosystem integration over maximum speech clarity. Budget-conscious shoppers should note that several competitors in the same price range—including the Elehear Beyond and the previous-generation Apple AirPods Pro 2—achieved higher overall scores in our testing.

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.
