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.
Choice

Signia Styletto AX
The Signia Styletto AX is a premium prescription behind-the-ear hearing aid that earned an A grade with a SoundScore of 4.3/5 in our lab testing, ranking #21 of 39 prescription hearing aids tested. Priced at $4,398, this 2022 release features a distinctive slim design with rechargeable batteries and iPhone streaming capability. In our testing, the Styletto AX demonstrated strong speech clarity in quiet environments, scoring 4.0/5—0.63 points above the category average. Speech in noise performance was above average at 2.3/5 (+0.17 vs category), though this remains mixed in absolute terms, suggesting challenging listening situations may still require additional strategies. Own-voice comfort scored a solid 3.0/5, sitting 0.30 points above average. Music streaming quality measured 3.1/5, performing 0.34 points above the category average for solid audio fidelity when streaming from compatible devices. Feedback handling scored 3.9/5—solid in absolute terms, though 0.82 points below the category average of 4.72/5, which is worth noting if feedback stability is a priority. The Styletto AX has earned Expert's Choice Awards in both 2023 and 2024. However, buyers in this premium price tier should be aware that several competitors offer higher SoundScores, including the Phonak Sphere Infinio (4.98/5) and Oticon Intent (4.83/5). The Styletto AX may appeal most to those prioritizing its sleek aesthetic and strong quiet-environment speech performance over maximum scores in noise or feedback handling.
