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.

Starkey Evolv AI Hero
StarkeySoundGrade B

Starkey Evolv AI

The Starkey Evolv AI is a premium behind-the-ear prescription hearing aid released in 2022, currently available at $4,598. In HearAdvisor's lab testing, it earned a B grade with a SoundScore of 3.9/5, ranking #28 of 36 prescription hearing aids tested. This device shows notable strengths in specific performance areas. Music streaming quality stands out at 3.7/5, scoring 1.06 points above the category average—making it a solid choice for users who prioritize audio entertainment. Speech in noise performance reaches 2.8/5, which is 0.81 points above the category average, though the absolute score reflects mixed real-world performance in challenging listening environments. Speech in quiet is solid at 3.4/5, slightly above average. The Evolv AI does show weaknesses in two key areas. Own voice comfort scores 2.1/5, falling 0.65 points below the category average, which may affect how natural your own speech sounds. Feedback handling, while solid in absolute terms at 3.5/5, runs 1.21 points below the category average of 4.71/5—meaning competitors in this price tier generally offer better feedback suppression. At this premium price point, several alternatives deliver stronger overall performance, including the Phonak Sphere Infinio and Oticon Intent. However, the Evolv AI's Expert's Choice Award recognition in 2023 and 2024 reflects its practical strengths. This hearing aid may suit users who prioritize music streaming quality and improved speech understanding in noise over own-voice comfort, and who value Starkey's feature set including rechargeable batteries and hands-free calling for both iPhone and Android.
