Uses Official HearAdvisor Lab Data
MDHearing Volt Hero
MDSoundScore 3.0Grade B

MDHearing Volt

The MDHearing Volt is a budget-priced prescription hearing aid released in 2020, earning a B grade with a SoundScore of 3.0/5 in our lab testing. At $397, it sits in the lowest price tier for prescription devices, ranking #34 of 39 in its category. In our testing, the Volt showed a mixed performance profile with one standout strength: feedback handling scored an excellent 5.0/5, which is 0.28 points above the category average. This means users can expect minimal whistling or squealing during typical wear. However, speech performance was limited, with speech in quiet scoring 1.8/5 (1.65 points below average) and speech in noise at 1.0/5 (1.11 points below average). Own voice comfort was mixed at 2.6/5, roughly matching the category average. Music streaming capability was not functional in our testing, scoring 0.0/5—a significant limitation for users who want to stream audio from their phone. This is 2.76 points below the prescription hearing aid category average. The Volt may appeal to budget-conscious consumers who prioritize basic amplification and feedback-free wear over advanced speech enhancement or streaming features. Those seeking stronger speech performance in the same price range may want to consider alternatives like the RxEars Rxi, which scored 4.07/5 in our testing. The Volt's rechargeable battery and behind-the-ear design offer practical convenience, but its core sound performance reflects its entry-level positioning.

RCA Micro Hero
RCASoundScore 2.7Grade C

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.
