Audien Atom X vs Sontro Soundwave
Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

Audien Atom X
The Audien Atom X is a budget OTC hearing aid priced at $389 that earns a B grade with a SoundScore of 3.3/5 in our lab testing. This visible-in-ear style device ranks #54 of 65 OTC hearing aids tested, placing it in the bottom portion of its category. In our testing, the Atom X shows a mixed performance profile with notable strengths and weaknesses. Music streaming quality is a standout, scoring 3.3/5—a solid result that sits 1.38 points above the category average. Feedback handling is excellent at 5.0/5, meaning users can expect stable performance without whistling issues. However, the core speech intelligibility metrics are where this device falls short: speech in quiet scores just 1.5/5 (1.25 points below the OTC average), and speech in noise scores 1.0/5 (0.48 points below average). Own-voice comfort is mixed at 2.3/5, slightly below the category norm. At this price point, several alternatives offer stronger overall performance. Devices like the Elehear Beyond (4.34/5) and Apple AirPods Pro 2 (4.04/5) score meaningfully higher in the same price range. For those prioritizing value, the JLab Hear OTC delivers a similar SoundScore of 3.54/5 at a lower price. The Atom X may appeal to users who prioritize music streaming quality and want simple rechargeable convenience, but those seeking improved speech clarity—especially in challenging listening environments—should consider higher-performing alternatives in this competitive OTC category.

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.
