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.

Sony CRE-C20
The Sony CRE-C20 is a mid-priced OTC hearing aid with an invisible-in-ear design, available for $999. In our lab testing, it earned a B grade with a SoundScore of 3.5/5, ranking #37 of 65 OTC hearing aids tested. This device shows a notable split in performance. Speech clarity is a clear strength—speech in quiet scores 4.1/5, which is 1.33 points above the category average, and speech in noise scores 2.7/5, sitting 1.24 points above average despite being only mixed in absolute terms. These results suggest the CRE-C20 prioritizes conversational intelligibility in its tuning approach. However, the device has significant limitations. Music streaming scored 0.0/5, falling 1.92 points below the category average—a notable weakness for users who want to stream audio. Feedback handling is solid at 3.9/5, though it sits 0.64 points below the category average of 4.54/5. Own voice comfort is mixed at 2.9/5, slightly above the category average. The CRE-C20 responds well to adjustment, with the normalized score improving from 3.3/5 at initial fit to 4.2/5 when tuned—a 0.9-point gain. Buyers focused primarily on speech understanding in conversations may find value here, but those wanting music streaming or seeking the strongest overall OTC performance should note that several competitors in this price range, including the Sony CRE-E10 at 4.66/5, scored higher in our testing.
