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.

SigniaSoundGrade A

Signia Styletto AX

The Signia Styletto AX is a premium prescription behind-the-ear hearing aid released in 2022, priced at $4,398. In HearAdvisor's lab testing, it earns an A grade with a SoundScore of 4.3/5, ranking #19 among 36 prescription hearing aids tested. This device demonstrates strong speech-in-quiet performance at 4.0/5, scoring 0.71 points above the category average. Speech-in-noise shows mixed absolute results at 2.3/5, though this still sits 0.32 points above the category average of 1.96/5. Music streaming quality is solid at 3.1/5, exceeding the category average by 0.46 points—a meaningful advantage for users who frequently stream audio from their iPhone. Own-voice comfort scores a solid 3.0/5, slightly above category average. However, feedback handling at 3.9/5 falls 0.81 points below the category average of 4.71/5—solid in absolute terms but notably weaker than many prescription competitors in our testing. The Styletto AX has earned HearAdvisor's Expert's Choice Award in both 2023 and 2024. With its distinctive slim design, rechargeable batteries, and iPhone streaming capabilities, it may appeal to users prioritizing aesthetics and convenience alongside strong speech clarity in quieter environments. Those frequently in challenging noise situations or requiring maximum feedback stability may want to compare alternatives in this price tier.
