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 available for $299, earning a B grade with a SoundScore of 3.4/5 in our lab testing. This behind-the-ear device ranks #40 among 65 OTC hearing aids tested, placing it in the top 60% of its category. In our testing, the Lumen demonstrates mixed speech performance. Speech in quiet scores 2.5/5, falling 0.24 points below the category average. Speech in noise performs better at 2.0/5, which is 0.55 points above the category average—though this remains mixed in absolute terms. Where the device excels is feedback handling, achieving a perfect 5.0/5, which is 0.46 points above the already-strong category average of 4.54/5. The most significant limitation is music streaming, which scores 0.0/5—a full 1.92 points below the category average. Users who prioritize streaming audio from their phones should look elsewhere. The device uses disposable batteries rather than rechargeables. At this price point, buyers face a competitive landscape. Several alternatives in the same price range deliver substantially higher scores, with some reaching into the 4.2-4.7 range. The Lexie Lumen may suit budget-conscious consumers who prioritize stable, feedback-free amplification over streaming capabilities and don't require top-tier speech clarity. However, those willing to explore other options at similar prices may find significantly better overall performance.

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.
