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.

Otofonix Helix
The Otofonix Helix is a behind-the-ear amplification product priced at $695, earning a C grade with a SoundScore of 2.7/5 in our lab testing. This places it in the lower tier of the amplification product category, ranking #7 of 8 devices tested. In our standardized testing, the Helix demonstrates one clear strength: excellent feedback handling, scoring a perfect 5.0/5—well above the category average. This means users can expect stable performance without whistling or squealing during normal wear and head movements. However, the Helix shows significant limitations in other areas. Speech clarity scores are low in both quiet (1.0/5) and noisy (1.0/5) environments, falling below category averages by 1.11 and 0.37 points respectively. Music streaming capability scored 0.0/5, indicating this device is not suitable for those who want to stream audio content. Own-voice comfort is also a weakness, particularly in the tuned configuration. At this price point, consumers should be aware that several alternatives in the same range offer stronger overall performance. The Otofonix Helix may appeal to those who prioritize feedback-free operation above other factors, but those seeking better speech understanding or streaming functionality should explore other options in the amplification product category.
