Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

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.
Choice
Oticon More
The Oticon More is a premium behind-the-ear prescription hearing aid that earned an A grade with a SoundScore of 4.6/5 in our lab testing, placing it in the top 22% of the 36 prescription hearing aids we've evaluated. Released in 2021, this device remains competitive and has received HearAdvisor's Expert's Choice Award in both 2023 and 2024. In our testing, the Oticon More demonstrated strong speech clarity performance. Speech in quiet scored 4.0/5, which is 0.73 points above the category average—a notable margin that reflects genuine audibility advantages in everyday conversations. Speech in noise measured 2.7/5, which is above the category average by 0.75 points, though only mixed in absolute terms, meaning challenging listening environments may still require effort. Own-voice comfort scored a solid 3.1/5 (+0.35 vs category average), and music streaming measured 3.0/5 (+0.36 vs category average), both performing above typical prescription aids. Feedback handling scored 3.5/5, which is solid in absolute terms, though below the category average of 4.71/5 by 1.21 points—something to discuss with your hearing care provider. At $4,598, this is a premium-priced device offering iPhone and Android streaming, hands-free calling, and your choice of rechargeable or disposable batteries. The Oticon More is well-suited for those prioritizing speech clarity who want a proven performer from an established manufacturer. Competitors in this price range include the newer Oticon Intent (4.85/5) and Oticon Real (4.75/5), which may be worth comparing during your fitting appointment.
