Linner Mercury vs Starkey Genesis AI
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.

Starkey Genesis AI
The Starkey Genesis AI is a premium behind-the-ear prescription hearing aid released in 2023, priced at $4,798. In HearAdvisor's lab testing, it earned a B grade with a SoundScore of 3.7/5, ranking #31 of 36 prescription hearing aids tested. This device demonstrates solid speech clarity in quiet environments, scoring 3.5/5—0.13 points above the category average. Its standout feature is excellent feedback handling, achieving a perfect 5.0/5 score. Speech-in-noise performance lands at 2.3/5, which is 0.36 points above the category average but remains mixed in absolute terms. Music streaming scored 2.8/5, slightly above average (+0.16 points) though still in mixed territory. Own-voice comfort presents a notable weakness, scoring 2.2/5—0.55 points below the category average. This may be a consideration for users sensitive to how their own voice sounds while wearing hearing aids. The Genesis AI showed meaningful improvement with professional tuning, with the normalized score jumping from 3.5/5 (Initial) to 4.3/5 (Tuned), suggesting that proper fitting is particularly important for this device. At this premium price point, competitors including the Phonak Sphere Infinio (5.0/5), Oticon Intent (4.85/5), and Oticon Real (4.75/5) deliver stronger overall sound performance. The Genesis AI may suit users who prioritize Starkey's ecosystem, hands-free calling features, and robust feedback control, but those seeking top-tier sound quality in this price range have higher-scoring alternatives to consider.
