Speech performance is solid in quiet environments at 3.1/5, measuring 0.36 points above average. Speech in noise scores 2.0/5, which is above the category average by 0.56 points, though this remains a mixed result in absolute terms. The Cearvol Wave shows some trade-offs in other areas. Own-voice comfort scores 2.1/5, falling 0.41 points below the category average—a consideration for those sensitive to how their own voice sounds while wearing hearing aids.

OticonSoundScore 4.7Grade A

Oticon Zeal

The Oticon Zeal is a premium prescription hearing aid in the invisible-in-ear style, carrying an A grade with a SoundScore of 4.7/5 in our lab testing. Priced at $4,798, it ranks #6 among 39 prescription hearing aids tested, placing it in the top 13% of its category. Speech performance is where the Zeal truly excels. Our testing measured an excellent 4.9/5 for speech in quiet—1.48 points above the category average—making it one of the strongest performers for everyday conversations. Speech in noise also scores a solid 3.0/5, sitting 0.93 points above the category average of 2.11/5, indicating reliable performance in moderately challenging listening environments. Music streaming quality registers at a solid 3.3/5, which is 0.54 points above the category average. However, the Zeal shows some limitations in other areas. Own-voice comfort scores a mixed 2.0/5, falling 0.70 points below the category average—something to consider if own-voice naturalness is a priority. Feedback handling measures at 3.3/5, which is solid in absolute terms but sits 1.42 points below the category average of 4.72/5. The Oticon Zeal is best suited for wearers who prioritize exceptional speech clarity and want a discreet, invisible-in-ear form factor. Those especially sensitive to feedback or own-voice effects may want to discuss these trade-offs with their hearing care provider during fitting.
