Apple AirPods Pro 3

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.

Feedback handling is equally impressive at 5.0/5, meaning users can expect excellent stability without whistling or squealing during normal use.

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.

Linner Mercury
The Linner Mercury is a budget-priced OTC hearing aid that earns a B grade with a SoundScore of 3.1/5 in our lab testing. Priced at $387, it ranks #60 of 65 devices in the OTC Hearing Aid category, placing it in the top 91% of the category. In our testing, the Mercury shows a mixed performance profile. Its standout strength is excellent feedback handling at 4.7/5, which is 0.16 points above the category average—meaning users are unlikely to experience whistling or squealing during normal use. However, speech clarity metrics fall below category norms: speech in quiet scores 2.2/5 (0.62 points below average), and speech in noise scores a low 1.0/5 (0.48 points below average). Own-voice comfort also scores low at 1.6/5, sitting 0.91 points below the category average. Music streaming is a notable weakness, scoring 0.0/5—a full 1.92 points below the category average. Users who prioritize streaming audio from their phone should consider alternatives. The device uses a rechargeable battery and features a visible in-ear design with power dome coupling. At this price point, several competitors offer stronger overall performance. The Linner Mercury may appeal to budget-conscious consumers who prioritize feedback-free operation over speech clarity and streaming quality, but those seeking better speech understanding in challenging environments should explore higher-scoring options in this price range.
