Speech in quiet is solid at 3.2/5, though slightly below the category average. Music streaming scores 2.8/5, above average but only mixed in absolute terms. At this price point, buyers should consider alternatives. The Rexton Reach R-Li T80 at Costco scores 4.58/5 in the same price range, while lower-priced options like the Lexie B3 (4.76/5) offer stronger overall performance. The Jabra Enhance Pro 20 may suit users who prioritize own-voice comfort and feedback stability over challenging listening environments, but those needing robust noise handling should explore other options.

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.
