How We Test

The Oticon Zeal is a premium prescription invisible-in-ear hearing aid priced at $4,798. In our lab testing, it achieved a SoundScore of 4.26/5, positioning it as a strong performer in the prescription hearing aid category with a score 0.35 points above the category average of 3.91.

Speech performance is where the Zeal truly excels. Speech in quiet earned an excellent 4.5/5, measuring 1.07 points above the category average. Speech in noise scored 2.9/5—above the category average by 1.37 points, though only mixed in absolute terms, reflecting the inherent challenges all hearing aids face in noisy environments. Music streaming quality is solid at 3.3/5, coming in 0.69 points above average for the category.

The tradeoffs center on own voice comfort and feedback handling. Own voice scored 2.0/5, falling 0.73 points below the category average—a consideration for users sensitive to how their own speech sounds. Feedback handling measured 3.3/5, which is solid in absolute terms but sits 1.44 points below the category average, suggesting users may need to be mindful of feedback in challenging situations.

The Oticon Zeal is best suited for users who prioritize speech clarity and streaming quality in a discreet invisible form factor, and who are willing to accept some compromises in own voice comfort. Professional tuning improved the normalized score from 4.2/5 to 4.5/5, indicating meaningful benefit from thorough fitting.
