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

RCA In-Ear
The RCA In-Ear is a budget-priced OTC hearing aid available for $249, earning a C grade with a SoundScore of 2.8/5 in our lab testing. This places it near the bottom of the OTC hearing aid category, ranking 64th out of 65 devices tested. In our standardized testing, the RCA In-Ear shows a mixed performance profile. Its standout strength is excellent feedback handling, scoring a perfect 5.0/5—0.46 points above the category average. This means users are unlikely to experience whistling or squealing during normal wear. Own-voice comfort scores 2.6/5, which is essentially at the category average (+0.09 points), offering mixed but acceptable performance for how your own voice sounds while wearing the devices. However, the core speech performance metrics present significant limitations. Speech in quiet scores just 1.0/5, falling 1.79 points below the category average, and speech in noise also scores 1.0/5, sitting 0.48 points below average. Music streaming scored 0.0/5, indicating this device is not suitable for audio entertainment purposes. At this price point, buyers have considerably stronger options. Competitors like the Lucid Enrich Pro and JLab Hear OTC offer better sound performance at lower prices. The RCA In-Ear may appeal to those prioritizing feedback-free wear above speech clarity, but most users seeking meaningful hearing benefit should consider higher-performing alternatives in this budget segment.

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.
