Apple AirPods Pro 2
The Apple AirPods Pro 2 is a budget-priced OTC hearing aid that earns an A grade with a SoundScore of 4.1/5 in our lab testing, placing it in the top 26% of OTC hearing aids tested. At $249, it represents one of the more affordable options in the category while delivering strong overall performance. In our testing, the AirPods Pro 2 shows particular strength in speech clarity for quiet environments, scoring 4.2/5—a strong result that sits 1.38 points above the category average. Music streaming is where this device truly excels, earning 4.4/5 and outperforming the category average by a substantial 2.48 points. Feedback handling is excellent at 5.0/5, meaning users should experience virtually no whistling issues. The device does have limitations. Own-voice comfort scores 1.9/5, which is low in absolute terms and 0.61 points below the category average—users may notice their own voice sounds different or boomy. Speech in noise performance is above average for the category at 2.3/5 (+0.77 points), but this remains a mixed result in absolute terms, suggesting challenging listening environments will still be difficult. The AirPods Pro 2 is best suited for consumers already in the Apple ecosystem who want hearing support primarily in quieter settings and value excellent music and media streaming. Those frequently in noisy environments or sensitive to own-voice changes may want to consider alternatives.

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.
