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.

Sontro Soundwave Hero
SontroSoundScore 3.0Grade B

Sontro Soundwave

The Sontro Soundwave is a mid-priced OTC hearing aid that earns a B grade with a SoundScore of 3.0/5 in our lab testing. At $849, this behind-the-ear device uses disposable batteries and sits in the lower tier of OTC performance, ranking #61 of 65 devices in its category. The Soundwave's strongest attribute is own-voice comfort, scoring 3.6/5—a solid result that sits 1.09 points above the OTC category average. This makes it relatively comfortable for wearers who are sensitive to hearing their own voice sound unnatural or boomy. However, other performance areas present significant limitations. Speech clarity scores are below average in both quiet and noisy environments. Speech in quiet scores 2.7/5 (0.12 points below average), while speech in noise drops to 1.2/5 (0.28 points below average). Feedback handling is a notable weakness at 2.5/5, falling 2.04 points below the category average of 4.54/5. Perhaps most limiting is the music streaming score of 0.0/5, indicating this device does not support phone audio streaming—a feature many competitors in this price range offer. Consumers prioritizing own-voice comfort on a moderate budget may find the Soundwave acceptable, but those seeking strong speech clarity or streaming capability should consider alternatives. Several higher-performing OTC devices are available at similar or lower price points, including options like the Lexie Lumen or HearingAssist Control that deliver comparable or better overall sound quality.
