Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

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.
Choice

Phonak Audéo Lumity
The Phonak Audéo Lumity is a premium prescription behind-the-ear hearing aid released in 2022, priced at $4,398. In HearAdvisor's independent lab testing, it earned an A grade with a SoundScore of 4.1/5, ranking #23 among 39 prescription hearing aids tested. This device demonstrates particular strength in music streaming, scoring 4.1/5—a strong result that sits 1.34 points above the category average. Feedback handling is excellent at 5.0/5, providing reliable stability during wear. Speech clarity in quiet environments is solid at 3.7/5, measuring 0.29 points above average for prescription aids. However, the Lumity shows notable limitations. Own-voice comfort scores just 1.0/5, falling 1.70 points below the category average—a significant weakness that may affect user satisfaction during conversations. Speech understanding in noisy environments, while technically above average by 0.04 points, remains mixed in absolute terms at 2.1/5. The Audéo Lumity includes rechargeable batteries, streaming compatibility with both iPhone and Android devices, and hands-free calling capability. It received HearAdvisor's Expert's Choice Award in both 2023 and 2024. This hearing aid may suit users who prioritize music enjoyment and streaming quality, though those sensitive to own-voice perception or frequently in noisy environments may want to explore alternatives in this price tier.
