Linner Mercury vs ReSound OMNIA RIE

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 ReSound OMNIA RIE is a premium prescription behind-the-ear hearing aid released in 2022, currently priced at $4,498. In HearAdvisor's lab testing, it earned a B grade with a SoundScore of 3.9/5, ranking #29 of 36 devices in the Prescription Hearing Aid category. This device shows a mixed performance profile in our testing. Its standout strength is speech clarity in quiet environments, scoring 3.7/5—a solid result that sits 0.42 points above the category average. Own-voice comfort also performs above average at 3.0/5, which may appeal to users concerned about how their own voice sounds while wearing hearing aids. However, the OMNIA RIE struggles significantly in challenging listening situations. Speech-in-noise performance scored just 1.0/5, falling 0.96 points below the category average—a notable limitation for users who frequently encounter noisy restaurants, gatherings, or other difficult acoustic environments. Feedback handling, while strong in absolute terms at 4.1/5, also trails the category average by 0.61 points. Music streaming delivers mixed results at 2.7/5, essentially matching the category average. The OMNIA RIE offers versatile connectivity with both iPhone and Android streaming, hands-free calling capability, and the flexibility of both rechargeable and disposable battery options. At its premium price point, however, several competitors in the same price range—including the Phonak Sphere Infinio and Oticon Intent—deliver substantially higher overall scores. This device may suit users who prioritize quiet conversation clarity and own-voice comfort over challenging noise performance.
