Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

HearingAssist Eaze
The HearingAssist Eaze is a budget-priced OTC hearing aid that earned a B grade with a SoundScore of 3.4/5 in our lab testing. At $399, it positions itself as an affordable behind-the-ear option in the crowded OTC market, ranking #43 of 65 OTC hearing aids tested. In our testing, the Eaze showed mixed results across performance categories. Its standout strength is 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, speech performance is a weakness: speech in quiet scored 2.6/5 (0.20 points below average) and speech in noise scored just 1.3/5 (also 0.20 points below average), which may limit benefit in challenging listening environments. The most significant limitation is music streaming, which scored 0.0/5—nearly 2 points below the category average of 1.92/5. Consumers who prioritize streaming audio from their phones should consider alternatives. Own-voice comfort also scored below average at 2.2/5, which may affect how natural users sound to themselves. At this price point, buyers have several higher-scoring alternatives to consider, including the Elehear Beyond (4.34/5) and Apple AirPods Pro 2 (4.04/5). The Eaze may suit budget-conscious consumers who prioritize feedback-free wear over streaming capability and don't frequently encounter noisy environments.
Choice

Sennheiser All-Day Clear Slim
The Sennheiser All-Day Clear Slim is a premium OTC behind-the-ear hearing aid priced at $1,499, earning an A grade with a SoundScore of 4.1/5. This places it in the top 23% of OTC hearing aids tested in our lab, ranking #16 among 65 devices in its category. This device excels in areas that reflect Sennheiser's audio heritage. Music streaming quality is a standout strength, scoring 3.8/5—a solid result that's 1.88 points above the OTC category average. Feedback handling is excellent at 5.0/5, meaning users can expect stability without whistling during typical use. Speech in quiet environments also performs well at 3.6/5, sitting 0.85 points above average for the category. However, the All-Day Clear Slim shows limitations in other areas. Speech in noise scores 1.5/5, matching the category average but representing a low absolute score that may challenge users in noisy restaurants or group conversations. Own-voice comfort is below average at 1.9/5, which could affect how natural users sound to themselves during conversation. The All-Day Clear Slim is best suited for consumers who prioritize music streaming and media consumption alongside hearing support, and who spend more time in quieter environments. Those frequently navigating noisy social situations may want to compare against higher-ranked competitors in this price range, such as the Lucid Tala or Audicus Omni 2, which achieve stronger overall scores.
