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.

Phonak Audéo EON Sphere

The Phonak Audéo EON Sphere is a premium behind-the-ear prescription hearing aid priced at $4,398. In HearAdvisor's lab testing, it earned a SoundScore of 5.0/5 and an A grade, placing it among the top performers in the prescription hearing aid category. Speech performance stands out as this device's greatest strength. Speech in noise scored an excellent 4.5/5, a full 2.53 points above the category average of 1.96/5—a substantial margin that makes this one of the strongest performers in challenging listening environments. Speech in quiet also performed well at 4.3/5, nearly a full point above the category average. These results suggest the Audéo EON Sphere may be particularly well-suited for users who frequently encounter noisy social settings or group conversations. Music streaming delivered a solid 3.7/5, more than a point above the category average of 2.64/5, indicating above-average audio fidelity for phone-streamed content. Own-voice comfort scored 2.8/5, which sits just above the category average but reflects mixed absolute performance—users sensitive to occlusion effects should discuss this with their hearing care provider. Feedback handling scored an excellent 4.6/5 in absolute terms, though it lands slightly below the category average of 4.71/5. The Audéo EON Sphere represents Phonak's latest premium technology and delivers strong results across most metrics in our standardized testing. It's best suited for users prioritizing speech clarity in difficult listening situations who are prepared for the premium price point.
