Cearvol Diamond X1 vs MDHearing Neo XS

The Cearvol Diamond X1 is a budget-priced OTC hearing aid available for $199, earning a B grade with a SoundScore of 3.7/5 in our lab testing. This visible-in-ear style device ranks #30 among 65 OTC hearing aids tested, placing it in the top 45% of its category. The Diamond X1 delivers a mixed performance profile with one notable strength: music streaming. With a score of 4.1/5, it performs 2.18 points above the category average—a substantial margin that makes it appealing for users who value audio entertainment through their hearing aids. Feedback handling is excellent at 4.5/5, providing stable performance during typical daily movements. Both iPhone and Android streaming are supported with rechargeable batteries for convenience. Speech performance presents a more modest picture. Speech in quiet scores 2.8/5, which is above the category average but only mixed in absolute terms. Speech in noise measures 1.7/5—above the category average of 1.48/5, though still low overall. Own-voice comfort is a weakness at 1.7/5, falling 0.81 points below the category average, which may cause your own voice to sound unnatural or boomy. The Diamond X1 is best suited for budget-conscious consumers who prioritize music and media streaming over maximum speech clarity. Those seeking stronger speech performance in challenging listening environments may want to consider higher-scoring alternatives in this price range, such as the Elehear Beyond or Apple AirPods Pro 2.

The MDHearing Neo XS is a budget-priced OTC hearing aid in the invisible-in-ear style, available for $397. In HearAdvisor lab testing, it earned a C grade with a SoundScore of 2.9/5, ranking #63 of 65 OTC hearing aids tested. Performance results reveal a mixed profile. The Neo XS shows strength in own-voice comfort, scoring 3.2/5—0.69 points above the category average—meaning wearers may experience less of the "boomy" quality that can accompany hearing aid use. Feedback handling is excellent at 5.0/5, sitting 0.46 points above average, so users should experience stable performance without whistling during typical wear. However, speech clarity is a significant limitation. Speech in quiet scores just 1.0/5, falling 1.77 points below the OTC category average. Speech in noise also scores 1.0/5, 0.48 points below average. Music streaming scored 0.0/5, which is 1.92 points below the category average—this device is not suited for audio entertainment. At this price point, several alternatives offer notably stronger performance. The Elehear Beyond (4.36/5), Apple AirPods Pro 2 (4.06/5), and Zepp Clarity Omni (3.88/5) all deliver better overall sound quality in the same price range. The Neo XS may appeal to those prioritizing own-voice comfort and feedback stability over speech intelligibility, but most users seeking meaningful hearing benefit should consider higher-scoring options.
