Lexie Lumen vs Sennheiser All-Day Clear Slim
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.

Sennheiser All-Day Clear Slim
The Sennheiser All-Day Clear Slim is a premium behind-the-ear OTC hearing aid priced at $1,499, earning an A grade with a SoundScore of 4.1/5 in our lab testing. This places it in the top 23% of the OTC hearing aid category, ranking #16 among 65 tested devices. In our testing, the All-Day Clear Slim demonstrates notable strengths in music streaming, scoring 3.8/5—a solid result that sits 1.88 points above the category average. This makes it one of the stronger performers for users who prioritize audio quality when streaming from their phone. Feedback handling is excellent at 5.0/5, measuring 0.46 points above the category average, meaning users can expect stable performance without whistling during typical daily activities. Speech clarity in quiet environments is solid at 3.6/5, coming in 0.85 points above the category average. However, speech in noise performance is low at 1.5/5, matching the category average—a common limitation across OTC devices. Own-voice comfort scores 1.9/5, which is 0.61 points below the category average, suggesting some users may notice their own voice sounds different or hollow. The All-Day Clear Slim includes rechargeable batteries and supports streaming to both iPhone and Android devices with hands-free functionality. At its price point, alternatives like the Lucid Tala and Audicus Omni 2 offer higher overall scores, though the Sennheiser may appeal to those who value the brand's audio heritage and prioritize music streaming quality over speech-in-noise performance.
