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.

Linner Mars
The Linner Mars is a budget-priced OTC hearing aid released in 2023, earning a B grade with a SoundScore of 3.2/5 in our lab testing. At $399, it falls in the lower price tier of the OTC category but ranks #55 of 65 OTC devices tested, placing it in the bottom 17% of its category. This visible-in-ear device presents a mixed performance profile with notable strengths and significant weaknesses. Music streaming is a standout feature, scoring an excellent 4.6/5—a full 2.68 points above the category average. Feedback handling is also excellent at 5.0/5, meaning users can expect stable performance without whistling during normal use. However, speech clarity presents challenges. Speech in quiet scores a low 1.9/5, falling 0.85 points below the category average. Speech in noise performance is particularly limited at 1.0/5, sitting 0.46 points below average. Own-voice comfort also scores low at 1.0/5, which is 1.51 points below the category average—users may notice their own voice sounding unnatural or boomy. The Linner Mars may suit budget-conscious consumers who prioritize music and media streaming over speech understanding in challenging environments. However, buyers seeking better speech performance should consider alternatives like the Elehear Beyond or Apple AirPods Pro 2, which offer stronger overall sound scores in the same price range.
