Audien Atom Pro 2 vs MDHearing Volt
Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

Audien Atom Pro 2
The Audien Atom Pro 2 is a budget-priced OTC hearing aid that earns a B grade with a SoundScore of 3.3/5 in our lab testing. Available for $289, this visible-in-ear device delivers solid performance in some areas while showing limitations in others. In our testing, the Atom Pro 2 demonstrated excellent feedback handling, scoring a perfect 5.0/5—0.46 points above the OTC category average. This means users can expect stable performance without whistling during typical daily activities. Own-voice comfort scored 2.6/5, slightly above the category average, suggesting acceptable naturalness when speaking. However, speech clarity presents a mixed picture. Speech in quiet scored 2.3/5 (0.49 points below category average), and speech in noise scored a low 1.3/5 (0.16 points below average). The most significant limitation is music streaming, which scored 0.0/5—nearly 2 points below the category average—indicating this device is not suitable for those who want to stream audio from their phone. At this price point, several alternatives offer stronger overall performance, including the Elehear Beyond and Apple AirPods Pro 2. The Atom Pro 2 may suit budget-conscious consumers who prioritize feedback-free operation over streaming capabilities and don't need maximum speech clarity. Those seeking better speech performance or any music streaming should consider higher-scoring options in this price range.

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.
