Lexie Lumen Hero
LexieSoundGrade B

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.

Linner Mercury Hero
LinnerSoundGrade B

Linner Mercury

The Linner Mercury is a budget-priced OTC hearing aid that earns a B grade with a SoundScore of 3.1/5 in our lab testing. Priced at $387, it ranks #60 of 65 devices in the OTC Hearing Aid category, placing it in the top 91% of the category. In our testing, the Mercury shows a mixed performance profile. Its standout strength is excellent feedback handling at 4.7/5, which is 0.16 points above the category average—meaning users are unlikely to experience whistling or squealing during normal use. However, speech clarity metrics fall below category norms: speech in quiet scores 2.2/5 (0.62 points below average), and speech in noise scores a low 1.0/5 (0.48 points below average). Own-voice comfort also scores low at 1.6/5, sitting 0.91 points below the category average. Music streaming is a notable weakness, scoring 0.0/5—a full 1.92 points below the category average. Users who prioritize streaming audio from their phone should consider alternatives. The device uses a rechargeable battery and features a visible in-ear design with power dome coupling. At this price point, several competitors offer stronger overall performance. The Linner Mercury may appeal to budget-conscious consumers who prioritize feedback-free operation over speech clarity and streaming quality, but those seeking better speech understanding in challenging environments should explore higher-scoring options in this price range.
