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

Linner Saturn
The Linner Saturn is a budget-priced OTC hearing aid that earned a B grade with a SoundScore of 3.6/5 in our lab testing. At $168, it sits in the most affordable tier of the OTC market and ranks #34 of 65 OTC hearing aids tested. In our testing, the Saturn demonstrated a notable strength in speech clarity during quiet environments, scoring 3.9/5—a solid result that's 1.10 points above the OTC category average. This suggests the device handles everyday conversations in calm settings reasonably well. Feedback handling also performed strongly at 4.4/5, though this sits slightly below the category average of 4.54/5. The Saturn shows meaningful limitations in other areas. Speech in noise scored just 1.1/5, falling 0.38 points below the category average—a low result that may affect performance in restaurants, group gatherings, or other challenging listening environments. Own-voice comfort scored 1.5/5, which is 1.01 points below average and low in absolute terms, suggesting some users may notice their own voice sounds unnatural. Music streaming scored 0.0/5, indicating this device is not suited for audio entertainment purposes. The Linner Saturn may appeal to budget-conscious consumers who primarily need help hearing speech in quieter environments and don't require music streaming capabilities. However, buyers seeking better noise handling or streaming features should consider alternatives in this price range, such as the higher-scoring Elehear Beyond or Apple AirPods Pro 2.
Choice

Oticon Zeal
The Oticon Zeal is a premium invisible-in-ear prescription hearing aid priced at $4,798. In HearAdvisor's lab testing, it earned an A grade with a SoundScore of 4.7/5, placing it in the top 11% of prescription hearing aids tested and ranking #5 of 36 devices in its category. Speech performance is where the Zeal truly excels. It achieved an excellent 4.9/5 in speech-in-quiet testing, scoring 1.56 points above the category average—among the strongest results we've measured. Speech-in-noise performance is solid at 3.0/5, which is 1.08 points above the category average of 1.96/5, making it notably better than typical prescription aids in challenging listening environments. Music streaming quality scores 3.3/5, sitting 0.66 points above category average and providing solid fidelity for phone audio. However, the Zeal shows some limitations in other areas. Own-voice comfort is mixed at 2.0/5, falling 0.75 points below the category average—users sensitive to how their own voice sounds may notice this. Feedback handling, while solid in absolute terms at 3.3/5, measures 1.41 points below the category average of 4.71/5. The Zeal is best suited for users who prioritize outstanding speech clarity in both quiet and moderately noisy settings, and who value quality audio streaming. Those particularly sensitive to own-voice perception or who need maximum feedback stability may want to discuss these tradeoffs with their hearing care provider.
