Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

BlaidsX Neuro
The BlaidsX Neuro is a mid-priced behind-the-ear OTC hearing aid priced at $799, earning a B grade with a SoundScore of 3.4/5 in our lab testing. This places it in the top 68% of OTC hearing aids tested, though it falls below the category average of 3.71. In our testing, the BlaidsX Neuro showed notable strengths in speech clarity for quiet environments, scoring 0.54 points above the category average. Feedback handling was excellent at 5.0/5, ranking among the best we've measured and 0.46 points above average. These results suggest the device may work well for conversations in calm settings where background noise isn't a factor. However, the device showed significant limitations in other areas. Speech in noise performance scored low at 1.0/5, falling 0.48 points below the category average—a concern for users who need help in challenging listening environments. Own-voice comfort also scored below average at 1.7/5, and music streaming scored 0.0/5, making it unsuitable for those who want to stream audio content. At this price point, buyers face strong competition. Devices like the Sony CRE-E10 and Lexie B2 Plus offer substantially higher overall scores in the same price range. The BlaidsX Neuro may suit users who primarily need help with face-to-face conversation in quiet spaces and don't require streaming capabilities, but those seeking versatile performance should consider alternatives.

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.

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.
