Cearvol Diamond X1
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.
Choice

Elehear Beyond
The Elehear Beyond is a budget-priced OTC hearing aid that delivers A-grade performance in our lab testing, ranking #8 among 65 OTC hearing aids tested. At $431, this 2024 behind-the-ear device earned our Expert's Choice Award and represents strong value in the entry-level price tier.

Music streaming quality also impressed at 3.8/5, exceeding the category average by 1.88 points. Speech understanding in noisy settings scored 2.3/5, which is above the category average of 1.48/5 but remains mixed in absolute terms—a common challenge across OTC devices. Feedback handling proved excellent at 4.5/5, essentially matching the category average. Own-voice comfort scored 2.6/5, slightly above the OTC average but mixed overall—users sensitive to their own voice may notice some occlusion effects. The device uses a rechargeable battery and supports streaming to both iPhone and Android devices with hands-free functionality. The Elehear Beyond is well-suited for budget-conscious consumers seeking reliable speech clarity in quieter listening situations and quality audio streaming. Those who frequently encounter challenging noise environments may find the speech-in-noise performance adequate but not exceptional.
