MDHearing Volt

The MDHearing Volt is a budget-priced prescription hearing aid available for $397, earning a B grade with a SoundScore of 3.1/5 in our lab testing. This behind-the-ear, rechargeable device ranks #32 of 36 prescription hearing aids tested, placing it in the top 86% of its category. In our standardized testing, the Volt demonstrates excellent feedback handling at 5.0/5, scoring 0.29 points above the category average. This represents a genuine strength, as the device remained stable under our challenge protocols without audible squealing or whistling. However, speech performance presents significant limitations: speech in quiet scored 1.8/5 (1.57 points below the category average of 3.32), while speech in noise scored 1.0/5 (0.96 points below the 1.96 average). Own-voice comfort measured 2.6/5, a mixed result that falls 0.15 points below the category average. Music streaming is notably limited at 0.0/5, scoring 2.64 points below the category average—users prioritizing phone streaming should consider alternatives. The Volt showed no improvement between Initial and Tuned fits, with both configurations yielding identical scores of 3.1/5. The MDHearing Volt may suit budget-conscious consumers who prioritize basic amplification and excellent feedback stability over speech clarity or streaming features. However, shoppers in this price range should note that alternatives like the RxEars Rxi offer substantially higher performance at similar pricing.

Resound Vivia 9 60S microRIE

The Resound Vivia 9 60S microRIE is a premium prescription behind-the-ear hearing aid released in 2025, currently available at $3,798. In HearAdvisor's lab testing, it earned a B grade with a SoundScore of 3.9/5, ranking #27 of 36 prescription hearing aids tested. This device demonstrates a mixed performance profile in our testing. Own-voice comfort is a notable strength, scoring 3.4/5—a solid result that sits 0.65 points above the category average, which may appeal to users sensitive to the hollow or boomy sound of their own speech. Speech clarity in quiet environments also performs well at 3.4/5, slightly above the category average. However, the Vivia 9 shows significant limitations in challenging listening situations. Speech in noise scored just 1.1/5, falling 0.81 points below the prescription hearing aid average—a substantial gap that suggests difficulty in restaurants, group conversations, or other noisy environments. Feedback handling, while strong in absolute terms at 4.2/5, still lands 0.51 points below what we typically see from prescription devices. Music streaming quality is mixed at 2.6/5, essentially matching the category average. At this premium price point, the Vivia 9 faces stiff competition. Several same-priced alternatives, including the Phonak Sphere Infinio and Oticon Intent, achieved notably higher overall scores in our testing. Consumers prioritizing noise performance may want to explore these options or consider lower-priced alternatives like the Sennheiser All Day Clear that delivered stronger overall results in our lab.
