Uses Official HearAdvisor Lab Data
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.

Sontro Soundwave Hero
SontroSoundScore 3.0Grade B

Sontro Soundwave

The Sontro Soundwave is a mid-priced OTC hearing aid that earns a B grade with a SoundScore of 3.0/5 in our lab testing. At $849, this behind-the-ear device uses disposable batteries and sits in the lower tier of OTC performance, ranking #61 of 65 devices in its category. The Soundwave's strongest attribute is own-voice comfort, scoring 3.6/5—a solid result that sits 1.09 points above the OTC category average. This makes it relatively comfortable for wearers who are sensitive to hearing their own voice sound unnatural or boomy. However, other performance areas present significant limitations. Speech clarity scores are below average in both quiet and noisy environments. Speech in quiet scores 2.7/5 (0.12 points below average), while speech in noise drops to 1.2/5 (0.28 points below average). Feedback handling is a notable weakness at 2.5/5, falling 2.04 points below the category average of 4.54/5. Perhaps most limiting is the music streaming score of 0.0/5, indicating this device does not support phone audio streaming—a feature many competitors in this price range offer. Consumers prioritizing own-voice comfort on a moderate budget may find the Soundwave acceptable, but those seeking strong speech clarity or streaming capability should consider alternatives. Several higher-performing OTC devices are available at similar or lower price points, including options like the Lexie Lumen or HearingAssist Control that deliver comparable or better overall sound quality.
