HearingAssist Eaze

The HearingAssist Eaze is a budget-priced OTC hearing aid released in 2023, earning a B grade with a SoundScore of 3.4/5 in our lab testing. At $399, it sits in the most affordable price tier of the OTC market, though it ranks #43 of 65 devices in its category. In our standardized testing, the Eaze demonstrates excellent feedback handling, scoring a perfect 5.0/5—0.46 points above the category average. This means users can expect stable performance without whistling during typical daily activities. However, the device shows limitations in other areas: speech clarity scores are mixed at 2.6/5 in quiet and low at 1.3/5 in noisy environments, both falling slightly below category averages. The most significant limitation is music streaming, which scored 0.0/5—nearly 2 points below the category average. Buyers who prioritize phone streaming for music or media should consider alternatives. Own-voice comfort is also mixed at 2.2/5, approximately 0.31 points below average for OTC devices. At this price point, shoppers have several higher-scoring alternatives to consider, including the Elehear Beyond and Apple AirPods Pro 2, which offer stronger overall performance. The HearingAssist Eaze may suit budget-conscious buyers who prioritize feedback stability over streaming capabilities and can accept modest speech performance in challenging listening situations.

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.
