Apple AirPods Pro 3
The Apple AirPods Pro 3 is a budget-priced OTC hearing aid released in 2025, earning a B grade with a SoundScore of 3.3/5 in our lab testing. At $250, it sits in the most affordable price tier of OTC devices, though its overall sound performance ranks #49 of 65 in the category. This device delivers standout performance in music streaming, scoring a strong 4.3/5—a full 2.38 points above the category average. Feedback handling is equally impressive at 5.0/5, meaning users can expect excellent stability without whistling or squealing during normal use. These strengths make the AirPods Pro 3 particularly appealing for users who prioritize media consumption alongside hearing assistance. However, speech clarity presents a more mixed picture. Speech in quiet scores 2.3/5, falling 0.53 points below the category average. Speech in noise measures 1.8/5, which is above the category average but still low in absolute terms. Own-voice comfort also trails at 1.9/5, sitting 0.61 points below typical OTC performance. The AirPods Pro 3 is best suited for users already invested in the Apple ecosystem who want hearing assistance combined with premium streaming quality. Those prioritizing speech understanding in conversations may want to explore alternatives like the Apple AirPods Pro 2, which scores higher overall at a lower listed price, or the Elehear Beyond at the top of this price range.

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.
