Linner Mercury vs Yeasound RIC700

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 RIC700 is a budget-priced OTC hearing aid that delivers surprisingly strong performance in our lab testing, earning an A grade with a SoundScore of 4.3/5. At $399, this behind-the-ear device ranks #10 out of 65 OTC hearing aids tested, placing it in the top 14% of its category. Speech clarity is where this device truly shines. In our quiet-environment testing, the RIC700 scored 4.2/5—a strong result that sits 1.41 points above the OTC category average of 2.79/5. Speech in noise performance scored 1.9/5, which is above the category average but low in absolute terms, meaning challenging listening environments will still present difficulties. Feedback handling is excellent at 4.6/5, virtually matching the category norm. The RIC700 does show some trade-offs. Own-voice comfort scored 2.0/5, falling 0.51 points below the category average—users may notice their own voice sounds different or hollow. Music streaming quality scored 2.9/5, which is above average for the category but only mixed in absolute terms, so audiophiles may want to manage expectations. This device includes modern conveniences like rechargeable batteries and streaming compatibility with both iPhone and Android devices, plus hands-free functionality. For budget-conscious consumers prioritizing speech understanding in quieter settings, the Yeasound RIC700 offers strong value. However, shoppers should also consider the higher-scoring Yeasound RIC800 or Sony CRE-E10 in the same price range if maximum performance is the priority.
