Linner Mercury vs Rexton Reach R-Li T80 at Costco

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 Rexton Reach R-Li T80, available exclusively at Costco for $1,500, is a behind-the-ear prescription hearing aid that earned an A grade and ranks #11 of 36 devices in its category in our lab testing. This 2024 release earned HearAdvisor's Expert's Choice Award, reflecting its strong overall performance. In our standardized testing, the Reach R-Li T80 delivered a SoundScore of 4.6/5, placing it in the top 28% of prescription hearing aids. Speech clarity stands out as a particular strength, scoring 3.9/5 in quiet environments—0.54 points above the category average. Own-voice comfort also impressed at 3.6/5, a full 0.85 points above average, suggesting wearers may experience less of the "talking in a barrel" sensation that can occur with hearing aids. Feedback handling is excellent at 4.8/5. Speech-in-noise performance scores 2.5/5, which is above the category average by 0.54 points but remains mixed in absolute terms—a common challenge across prescription devices. Music streaming similarly scores 2.7/5, slightly above average but not a standout feature. This device supports both iPhone and Android streaming, offers hands-free functionality, and uses rechargeable batteries. For Costco members seeking a prescription hearing aid with reliable speech clarity, strong own-voice comfort, and excellent feedback control at a mid-tier price point, the Reach R-Li T80 represents solid value in our testing framework.
