Linner Saturn
The Linner Saturn is a budget-priced OTC hearing aid earning a B grade with a SoundScore of 3.6/5 in our lab testing. Priced at $168, it sits in the affordable tier of the OTC market and ranks #34 of 65 OTC devices tested. In our testing, the Saturn demonstrates a notable strength in speech clarity during quiet environments, scoring 3.9/5—a solid result that measures 1.10 points above the OTC category average of 2.79/5. This suggests the device may work well for conversations in calm settings. Feedback handling also performs strongly at 4.4/5 in absolute terms, though this falls slightly below the category average of 4.54/5. The device shows clear limitations in other areas. Speech in noise scores just 1.1/5, falling 0.38 points below category average—a meaningful gap for users who need help in challenging listening environments. Own-voice comfort is low at 1.5/5, measuring 1.01 points below average, which may affect how natural your own speech sounds while wearing the aids. Music streaming scored 0.0/5, indicating this device is not suited for audio entertainment. The Linner Saturn is best suited for budget-conscious users who primarily need help with face-to-face conversations in quiet settings and don't require streaming capabilities. Shoppers willing to spend in this price range should also consider alternatives like the Elehear Beyond or Apple AirPods Pro 2, which scored higher in our testing.
