Lucid Ultra 128  Hero
LucidSoundScore 4.4Grade A

Lucid Ultra 128

The Lucid Ultra 128 is a premium behind-the-ear prescription hearing aid priced at $5,000, earning an A grade with a SoundScore of 4.4/5 in our lab testing. It ranks #17 among 39 prescription hearing aids tested, placing it in the top 41% of its category. Speech performance is where the Lucid Ultra 128 truly excels. In our lab testing, speech in quiet scored a strong 4.3/5, which is 0.95 points above the category average. Speech in noise performance reached 2.7/5, which sits above the category average by 0.59 points, though it remains mixed in absolute terms. This suggests the device handles conversational clarity well in our test scenarios, particularly in quieter environments. The device does face some challenges. Feedback handling scored just 1.7/5, falling 3.02 points below the category average of 4.72/5—a notable weakness compared to other prescription aids in our testing. Music streaming also came in below average at 2.3/5, which is 0.46 points under the category norm. Own-voice comfort scored a mixed 2.9/5, slightly above average. At this price point, several competitors in our database achieved higher overall scores, including the Phonak Sphere Infinio and Oticon Intent. The Lucid Ultra 128 features disposable batteries and supports both iPhone and Android streaming. It may appeal to users who prioritize speech clarity in quiet settings and are less concerned about feedback stability or music streaming fidelity in our standardized tests.

MDHearing Neo XS Hero
MDHearingSoundScore 2.9Grade C

MDHearing Neo XS

The MDHearing Neo XS is a budget OTC hearing aid featuring an invisible-in-ear design, priced at $397. In our lab testing, it earned a C grade with a SoundScore of 2.9/5, ranking #63 of 65 devices in the OTC hearing aid category. This device presents a mixed performance profile. Its standout strength is excellent feedback handling at 5.0/5, scoring 0.46 points above the category average—meaning users should experience minimal whistling or squealing during everyday use. Own-voice comfort is also solid at 3.2/5, sitting 0.69 points above average, which suggests the device manages occlusion reasonably well for its invisible design. However, speech clarity is a significant weakness. Speech in quiet scored just 1.0/5, falling 1.77 points below the category average, while speech in noise scored 1.0/5, sitting 0.48 points below average. Music streaming scored 0.0/5, coming in 1.92 points below average—indicating this device is not suitable for audio entertainment. These low absolute scores mean users may struggle to achieve meaningful speech benefit in our standardized test conditions. The invisible-in-ear form factor and rechargeable batteries offer convenience, but buyers should weigh this against the limited speech performance. Several competitors in the same price range—including the Elehear Beyond (4.34/5) and Apple AirPods Pro 2 (4.04/5)—deliver substantially better sound quality. The Neo XS may appeal to those prioritizing discretion and feedback-free wear over speech clarity, but most users seeking improved communication would benefit from exploring higher-performing alternatives.
