OticonSoundGrade A

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.

Signia Pure C&G IX

The Signia Pure C&G IX is a premium prescription behind-the-ear hearing aid released in 2023, currently available at $3,298. In HearAdvisor's lab testing, it earned an A grade with a SoundScore of 4.1/5, ranking #20 among 36 prescription hearing aids tested. This device demonstrates consistent strength across multiple performance areas. Speech in quiet scored a solid 4.0/5, sitting 0.65 points above the category average. Speech in noise performance, while above the category average by 0.25 points, remains mixed in absolute terms at 2.2/5—a common challenge across prescription devices. Feedback handling is a standout feature, achieving a perfect 5.0/5 and exceeding the already-high category average. Own-voice comfort scores a solid 3.2/5, running 0.45 points above the category average, which suggests good occlusion management. Music streaming performs solidly at 3.0/5, also above average for the category by 0.36 points. The device supports both iPhone and Android streaming along with hands-free functionality. Professional tuning yields meaningful improvement, with the normalized score increasing from 4.0/5 to 4.5/5. Buyers seeking top-tier performance in this price range should note that competitors like the Phonak Sphere Infinio (5.0/5) and Oticon Intent (4.85/5) scored higher in our testing. The Pure C&G IX may suit those who prioritize reliable feedback control and balanced everyday performance over maximum speech-in-noise capability.
