LexieSoundGrade A

Lexie B2 Plus

The Lexie B2 Plus is a mid-priced OTC hearing aid that earns an A grade with a SoundScore of 4.4/5, placing it in the top 9% of OTC devices tested in our lab. At $899, this behind-the-ear style device delivers strong performance in several key areas while showing some limitations worth considering. In our testing, the Lexie B2 Plus excels in speech clarity for quiet environments, scoring a strong 4.3/5—significantly above the OTC category average by 1.49 points. Own-voice comfort is a particular standout at 4.8/5, well above the category average by 2.29 points, meaning wearers are unlikely to experience the hollow or booming quality of their own voice that can make some hearing aids uncomfortable. Speech in noise performance scores 2.1/5, which is above the OTC category average by 0.58 points but remains mixed in absolute terms—typical for this device class. Music streaming scores 2.6/5, similarly above average by 0.68 points while remaining modest overall. Feedback handling at 2.8/5 falls below the category average by 1.74 points, which may require attention during phone calls or when wearing hats. The Lexie B2 Plus is a solid choice for users prioritizing speech clarity in quieter settings and natural own-voice comfort. It features rechargeable batteries and streaming compatibility with both iPhone and Android devices. This two-time Expert's Choice Award winner (2023, 2024) competes against devices like the higher-scoring Sony CRE-E10 in its price range, but offers a compelling balance of comfort and core speech performance.

Linner Mars Hero
LinnerSoundGrade B

Linner Mars

The Linner Mars is a budget-priced OTC hearing aid released in 2023, earning a B grade with a SoundScore of 3.2/5 in our lab testing. At $399, it falls in the lower price tier of the OTC category but ranks #55 of 65 OTC devices tested, placing it in the bottom 17% of its category. This visible-in-ear device presents a mixed performance profile with notable strengths and significant weaknesses. Music streaming is a standout feature, scoring an excellent 4.6/5—a full 2.68 points above the category average. Feedback handling is also excellent at 5.0/5, meaning users can expect stable performance without whistling during normal use. However, speech clarity presents challenges. Speech in quiet scores a low 1.9/5, falling 0.85 points below the category average. Speech in noise performance is particularly limited at 1.0/5, sitting 0.46 points below average. Own-voice comfort also scores low at 1.0/5, which is 1.51 points below the category average—users may notice their own voice sounding unnatural or boomy. The Linner Mars may suit budget-conscious consumers who prioritize music and media streaming over speech understanding in challenging environments. However, buyers seeking better speech performance should consider alternatives like the Elehear Beyond or Apple AirPods Pro 2, which offer stronger overall sound scores in the same price range.
