Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

Nuheara IQBuds Max
The Nuheara IQBuds Max is a budget-priced OTC hearing aid that earns a B grade with a SoundScore of 3.3/5 in our lab testing. Priced at $499, this visible-in-ear device from 2021 ranks #46 of 65 OTC hearing aids tested, placing it in the top 69% of its category. The standout feature of the IQBuds Max is its exceptional music streaming performance, scoring 4.3/5—a strong result that sits 2.38 points above the category average. For users who prioritize audio entertainment alongside hearing assistance, this device delivers notably better streaming fidelity than most OTC alternatives. However, speech performance presents a mixed picture. Speech in quiet scores 2.0/5, falling 0.78 points below the category average. Speech in noise is essentially at par with competitors at 1.5/5, which is above average for the category but low in absolute terms. Own voice comfort also trails the category average by 0.31 points with a score of 2.2/5. Feedback handling scores a solid 3.4/5 in absolute terms, though this falls 1.14 points below the category average. The IQBuds Max is best suited for users who value music and audio streaming quality over speech clarity, particularly those seeking an affordable entry point into amplification. Competing devices in this price range—including the Elehear Beyond (4.34/5) and Apple AirPods Pro 2 (4.04/5)—offer stronger overall sound performance for similar investment.

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.
