Lucid Ultra 128

The Lucid Ultra 128 is a premium behind-the-ear prescription hearing aid priced at $5,000, earning an A grade with a SoundScore of 4.4/5 in our lab testing. It ranks #16 of 36 devices in the Prescription Hearing Aid category. Speech performance is a clear strength for the Ultra 128. In our testing, speech in quiet scored a strong 4.3/5, landing 1.03 points above the category average. Speech in noise measured 2.7/5—above the category average by 0.74 points, though mixed in absolute terms. These results suggest the device prioritizes intelligibility in everyday listening situations. The Ultra 128 does show notable weaknesses. Feedback handling scored just 1.7/5, falling 3.01 points below the category average of 4.71/5—a significant gap that prospective buyers should consider. Music streaming measured 2.3/5, slightly below the category average. Own-voice comfort was mixed at 2.9/5, though this sits just above the category norm. The device uses disposable batteries and supports streaming to both iPhone and Android. At this price point, buyers may want to compare against higher-scoring competitors like the Phonak Sphere Infinio (5.0/5) or Oticon Intent (4.85/5). The Lucid Ultra 128 may suit those who prioritize speech clarity in quieter environments and can work with their hearing care provider to manage its feedback limitations.

MDHearing Volt Hero
MDSoundGrade B

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.
