Linner Mercury vs Yeasound RIC800

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.

The Yeasound RIC800 is a mid-priced OTC hearing aid that earned an A grade with a SoundScore of 4.8/5 in our lab testing, placing it #2 among 65 OTC devices tested. At $659, this behind-the-ear rechargeable device delivers performance that significantly outpaces the category average of 3.71/5. Speech clarity is a standout strength. The RIC800 scores 4.4/5 for speech in quiet—a strong result that sits 1.63 points above the OTC category average. Speech in noise performance is more mixed at 2.4/5, though this still lands 0.93 points above the typical OTC device. Music streaming is where this device truly excels, scoring 4.3/5 and outperforming the category average by a substantial 2.38 points—making it one of the better choices for consumers who frequently stream audio from their phone. Feedback handling is excellent at 5.0/5, meaning users shouldn't encounter whistling issues during normal wear. The tradeoff comes with own-voice comfort, which scores 2.1/5—a mixed result that falls 0.41 points below the category average. Some users may notice their own voice sounds more hollow or boomy than expected. The RIC800 earned a 2025 Expert's Choice Award and supports both iPhone and Android streaming. For consumers seeking strong speech performance and exceptional streaming quality in the OTC space, this device represents a compelling option. Those particularly sensitive to own-voice quality may want to compare alternatives, but overall performance places the RIC800 among the top tier of OTC hearing aids we've tested.
