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.

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.
