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.

MDHearing VoltMax Hero
MDSoundScore 3.0Grade B

MDHearing VoltMax

The MDHearing VoltMax is a behind-the-ear OTC hearing aid priced at $699, earning a B grade with a SoundScore of 3.0/5 in our lab testing. This places it in the lower tier of the OTC hearing aid category, ranking 62nd out of 65 devices tested. In our testing, the VoltMax delivered mixed results across key performance areas. Its standout strength is excellent feedback handling, scoring a perfect 5.0/5—above the category average by 0.46 points. This means users can expect stable performance without whistling or squealing during typical daily activities. However, speech clarity proved challenging, with speech-in-quiet scoring 1.9/5 (0.93 points below category average) and speech-in-noise at 1.0/5 (0.48 points below average). Own-voice comfort measured 2.4/5, slightly below the category norm. A significant limitation is music streaming, which scored 0.0/5—nearly 2 points below the category average. Users who prioritize phone streaming for calls or media should consider alternatives. The device features rechargeable batteries, offering convenience over disposable options. At this price point, several competitors deliver substantially stronger overall performance. The VoltMax may appeal to budget-conscious consumers who primarily need basic amplification with reliable feedback control and don't require streaming capabilities. Those seeking better speech clarity or music streaming should explore higher-scoring options in this price range.
