HearingAssist Eaze

The HearingAssist Eaze is a budget-priced OTC hearing aid released in 2023, earning a B grade with a SoundScore of 3.4/5 in our lab testing. At $399, it sits in the most affordable price tier of the OTC market, though it ranks #43 of 65 devices in its category. In our standardized testing, the Eaze demonstrates 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, the device shows limitations in other areas: speech clarity scores are mixed at 2.6/5 in quiet and low at 1.3/5 in noisy environments, both falling slightly below category averages. The most significant limitation is music streaming, which scored 0.0/5—nearly 2 points below the category average. Buyers who prioritize phone streaming for music or media should consider alternatives. Own-voice comfort is also mixed at 2.2/5, approximately 0.31 points below average for OTC devices. At this price point, shoppers have several higher-scoring alternatives to consider, including the Elehear Beyond and Apple AirPods Pro 2, which offer stronger overall performance. The HearingAssist Eaze may suit budget-conscious buyers who prioritize feedback stability over streaming capabilities and can accept modest speech performance in challenging listening situations.

Linner Mercury Hero

Linner Mercury

The Linner Mercury is a budget-priced OTC hearing aid that earns a B grade with a SoundScore of 3.1/5 in our lab testing. Priced at $387, it ranks #60 of 65 devices in the OTC Hearing Aid category, placing it in the top 91% of the category. In our testing, the Mercury shows a mixed performance profile. Its standout strength is excellent feedback handling at 4.7/5, which is 0.16 points above the category average—meaning users are unlikely to experience whistling or squealing during normal use. However, speech clarity metrics fall below category norms: speech in quiet scores 2.2/5 (0.62 points below average), and speech in noise scores a low 1.0/5 (0.48 points below average). Own-voice comfort also scores low at 1.6/5, sitting 0.91 points below the category average. Music streaming is a notable weakness, scoring 0.0/5—a full 1.92 points below the category average. Users who prioritize streaming audio from their phone should consider alternatives. The device uses a rechargeable battery and features a visible in-ear design with power dome coupling. At this price point, several competitors offer stronger overall performance. The Linner Mercury may appeal to budget-conscious consumers who prioritize feedback-free operation over speech clarity and streaming quality, but those seeking better speech understanding in challenging environments should explore higher-scoring options in this price range.
