Cearvol Diamond X1 vs RCA In-Ear

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 RCA In-Ear is a budget OTC hearing aid priced at $249, earning a C grade with a SoundScore of 2.8/5 in our lab testing. This places it near the bottom of the OTC category at #64 of 65 devices tested. Speech performance is a significant weakness for this device. Speech in quiet scores just 1.0/5, falling 1.79 points below the category average, while speech in noise also scores 1.0/5, sitting 0.48 points below average. These low absolute scores indicate limited benefit for understanding conversation in most listening situations. Music streaming scored 0.0/5, measuring 1.92 points below the category average—this device is not suitable for audio entertainment. The RCA In-Ear does show strength in feedback handling, scoring an excellent 5.0/5, which is 0.46 points above the category average. Own-voice comfort is mixed at 2.6/5, essentially matching the category average with only a 0.09-point advantage. The rechargeable battery design offers convenience for daily use. At this price point, consumers have substantially higher-performing alternatives. Devices like the Elehear Beyond (4.36/5), Apple AirPods Pro 2 (4.06/5), and several others in the same budget range deliver meaningfully better speech clarity and overall sound quality. The RCA In-Ear may appeal to those prioritizing feedback-free operation above all else, but most users seeking improved hearing will find better value elsewhere in the OTC market.
