RCA Micro

The RCA Micro is a budget-priced behind-the-ear OTC hearing aid available for $399. In our lab testing, it earned a C grade with a SoundScore of 2.7/5, placing it at #65 of 65 devices in the OTC Hearing Aid category. Speech performance represents the most significant limitation of this device. Speech in Quiet scores 1.0/5, which is 1.79 points below the category average, while Speech in Noise also scores 1.0/5, falling 0.48 points below average. These low absolute scores indicate limited benefit for understanding conversation in our standardized test conditions. The RCA Micro does excel in one area: feedback handling earns an excellent 5.0/5, which is 0.46 points above the category average. This suggests stable performance without whistling during typical use. Own Voice comfort scores a mixed 2.1/5, sitting 0.41 points below average. Music Streaming scores 0.0/5, falling 1.92 points below the category average, indicating this device is not suitable for audio entertainment. At this price point, several alternatives offer substantially stronger performance. The Elehear Beyond, Apple AirPods Pro 2, and Zepp Clarity Omni all score above 3.8/5 in the same price range. Consumers prioritizing speech clarity and overall sound quality should consider these higher-performing options. The RCA Micro may appeal to those who need basic amplification with reliable feedback control and prefer a simple rechargeable behind-the-ear design.

Sontro Soundwave Hero
SontroSoundScore 3.0Grade B

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.
