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.

Signia Silk Charge&Go IX
The Signia Silk Charge&Go IX is a premium prescription hearing aid featuring an invisible-in-ear design, currently available at $3,298. In HearAdvisor's lab testing, it earned a B grade with a SoundScore of 3.7/5, ranking #32 of 39 prescription hearing aids tested. This device demonstrates a notable strength in speech clarity for quiet environments, scoring an excellent 4.6/5—well above the category average by 1.22 points. Speech in noise performance is mixed at 2.2/5, though this still edges slightly above the category average. Feedback handling is strong at 4.3/5, providing reliable stability during typical wear, even if it falls just below the category average. The Silk Charge&Go IX has significant limitations to consider. Own-voice comfort scores low at 1.5/5, falling 1.20 points below the category average—a trade-off that may relate to the invisible form factor. Most notably, the device does not support music streaming, scoring 0.0/5 in that metric, which is 2.76 points below the category average. At this premium price point, several competitors deliver substantially higher overall performance, including the Phonak Sphere Infinio (4.98/5) and Oticon Intent (4.83/5). The Silk Charge&Go IX is best suited for users who prioritize an invisible, rechargeable design and primarily need clear speech understanding in quieter settings, while having minimal need for streaming audio content.
