MDHearing Neo XS vs ReSound OMNIA RIE
Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

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.

ReSound OMNIA RIE
The ReSound OMNIA RIE is a premium prescription behind-the-ear hearing aid released in 2022, currently available at $4,498. In HearAdvisor's lab testing, it earns a B grade with a SoundScore of 3.9/5, ranking #31 of 39 devices in the prescription hearing aid category. This device shows notable strengths in speech clarity for quiet environments, scoring 3.7/5—a solid result that sits 0.34 points above the category average. Own-voice comfort also performs above average at 3.0/5, which may appeal to users who find their own voice bothersome in other devices. Feedback handling is strong in absolute terms at 4.1/5, though it falls 0.62 points below the category average of 4.72/5. The OMNIA RIE's most significant limitation is speech in noise performance, scoring just 1.0/5—a low result that trails the category average by 1.11 points. For users who frequently encounter challenging listening environments like restaurants or group conversations, this represents a meaningful gap compared to alternatives. Music streaming scores a mixed 2.7/5, essentially matching the category average. The device offers flexible power options with both rechargeable and disposable batteries, plus streaming compatibility with iPhone and Android devices including hands-free functionality. However, at this premium price point, several competitors deliver stronger overall performance, including options from Phonak, Oticon, and Widex. The OMNIA RIE may suit users who prioritize quiet-environment clarity and own-voice comfort over noise-handling capabilities.
