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.

Sontro Soundwave
The Sontro Soundwave is a mid-priced OTC hearing aid priced at $849, earning a B grade with a SoundScore of 3.1/5 in HearAdvisor's lab testing. This behind-the-ear device uses disposable batteries and ranks #61 of 65 OTC hearing aids tested, placing it in the top 92% of its category. In our lab testing, the Soundwave shows a notable strength in own-voice comfort, scoring 3.6/5—a solid result that sits 1.09 points above the category average. This suggests users may experience less of the "talking in a barrel" sensation that can occur with some hearing aids. However, the device faces challenges in other key areas. Speech in quiet scores 2.7/5 (mixed, 0.12 points below average), while speech in noise registers at 1.2/5 (low, 0.28 points below average), indicating potential difficulty in challenging listening environments. The most significant limitations appear in music streaming and feedback handling. Music streaming scores 0.0/5, falling 1.92 points below the category average—a notable weakness for users who value audio entertainment. Feedback handling scores 2.5/5, which is 2.04 points below the category average of 4.54/5, suggesting the device may be more prone to whistling issues. At this price point, competitors offer substantially stronger performance. Devices like the Sony CRE-E10 and Lexie B2 Plus deliver significantly higher sound scores in the same price range. The Sontro Soundwave may suit those prioritizing own-voice comfort over speech clarity and streaming quality, but most users would benefit from exploring higher-performing alternatives at similar or lower prices.
