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 in HearAdvisor's lab testing, ranking #7 among 65 OTC devices. Priced at $899, this behind-the-ear rechargeable device has earned back-to-back Expert's Choice Awards in 2023 and 2024. In our testing, the B2 Plus demonstrates strong speech-in-quiet performance at 4.3/5, which is 1.49 points above the OTC category average. Own-voice comfort is excellent at 4.8/5, measuring 2.29 points above average—a notable strength that may appeal to users who find their own voice bothersome with other devices. Speech-in-noise scores 2.1/5, which is above the category average by 0.58 points but remains mixed in absolute terms, reflecting the broader challenge OTC devices face in noisy environments. The device does show a weakness in feedback handling, scoring 2.8/5—which is 1.74 points below the category average of 4.54/5. Users may encounter occasional whistling during activities that bring objects close to the ear. Music streaming performance is mixed at 2.6/5, though still 0.68 points above the OTC average. The Lexie B2 Plus offers both iPhone and Android streaming compatibility. It's well-suited for users prioritizing clear speech in quieter settings and natural own-voice perception, though those frequently in noisy environments or concerned about feedback stability may want to consider alternatives like the Sony CRE-E10 in this price range.
