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

Lexie Lumen
The Lexie Lumen is a budget-priced OTC hearing aid that earned a B grade with a SoundScore of 3.5/5 in our lab testing, placing it in the top 60% of the OTC category. At $299, this behind-the-ear device uses disposable batteries and represents one of the more affordable entry points into amplification. In our standardized testing, the Lumen demonstrated notably strong feedback handling, scoring 5.0/5 in the tuned configuration—0.46 points above the category average. This excellent stability means users can expect minimal whistling during typical daily activities. Speech in noise performance scored 2.0/5, which is above the category average by 0.55 points, though still mixed in absolute terms. The device shows clear limitations in certain areas. Music streaming scored 0.0/5, falling 1.92 points below category average—prospective buyers who prioritize phone streaming for music or media should consider alternatives. Speech in quiet performance is also slightly below average at 2.5/5, a mixed result that may affect understanding in everyday conversation. The Lexie Lumen is best suited for budget-conscious first-time users who prioritize stable, feedback-free amplification over streaming capabilities. However, shoppers in this price range have several higher-performing alternatives available, including the Sony CRE-E10 and Lexie B2 Plus, both of which scored significantly higher in our testing.

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.
