HearingAssist Eaze vs Otofonix Groove
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.

Otofonix Groove
The Otofonix Groove is a behind-the-ear prescription hearing aid priced at $795, earning a C grade with a SoundScore of 2.7/5 in our lab testing. This rechargeable BTE ranks #38 of 39 devices in the prescription hearing aid category, placing it in the bottom 5% of its class. In our testing, the Groove demonstrated excellent feedback handling at 5.0/5, scoring 0.28 points above the category average. This represents a genuine strength, with the device maintaining stability during our standardized challenge motions. However, speech performance was significantly limited, with speech in quiet scoring 1.0/5 (2.40 points below the category average of 3.40) and speech in noise also at 1.0/5 (1.11 points below average). Music streaming was not functional in our tests, scoring 0.0/5 against a category average of 2.76. Own-voice comfort also fell well below typical prescription hearing aid performance at 0.4/5, which is 2.30 points below the category average. At this price point, several lower-cost alternatives delivered stronger overall performance in our testing. Consumers seeking value in the prescription category may want to explore other options, though those requiring robust feedback control in a rechargeable BTE format may find the Groove's stability noteworthy despite its other limitations.
