Performance Metrics

SoundScore: 5 Acoustic Dimensions

Five lab measurements capture speech clarity in quiet, speech clarity in noise, own-voice naturalness, feedback control, and streaming quality. The purple SoundScore graph is the overall result, and the five graphs after it break it into individual measurements for the selected fit. Each curve shows how scores are spread across all tested hearing aids, and the dot and number mark the score for HearingAssist Eaze.

Lab Assessment

HearingAssist Eaze Independent Test Results

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.

Test Documentation

HearingAssist Eaze Fit Observations and Configuration

Our technicians documented observations during both Initial and Tuned fit conditions for the HearingAssist Eaze. The notes below detail the test configuration and any fitting considerations observed during measurement sessions.

Lab Notes

Initial fit observations

In our initial fit evaluation using closed domes, the HearingAssist Eaze achieved a normalized Initial Score of 3.4/5. Feedback handling was excellent at 5.0/5, providing stable amplification without whistling. Speech performance was mixed, with speech in quiet at 2.6/5 and speech in noise at 1.3/5—both slightly below the OTC category average. Own-voice comfort scored 2.2/5, and music streaming was notably limited at 0.0/5. The device delivers basic amplification with reliable stability but limited benefit for speech clarity in difficult listening situations.

Tuned fit observations

The tuned fit evaluation used the same closed dome configuration as initial fit, resulting in an identical normalized Tuned Score of 3.4/5. All individual metrics remained unchanged: excellent feedback handling at 5.0/5, speech in quiet at 2.6/5, speech in noise at 1.3/5, own-voice comfort at 2.2/5, and music streaming at 0.0/5. The lack of improvement between fits suggests the device has limited adjustability, and the initial configuration already represents its optimal performance in our testing protocol.
