Cearvol Wave
The Cearvol Wave is a budget-priced OTC hearing aid with a visible in-ear style, earning a B grade with a SoundScore of 3.9/5 in our lab testing. At $397, it ranks #22 among 65 OTC hearing aids tested, placing it in the top 32% of its category. This device demonstrates notable strengths in music streaming, scoring 4.1/5—a strong result that sits 2.18 points above the OTC category average. Speech performance is solid in quiet environments at 3.1/5, measuring 0.36 points above average. Speech in noise scores 2.0/5, which is above the category average by 0.56 points, though this remains a mixed result in absolute terms. The Cearvol Wave shows some trade-offs in other areas. Own-voice comfort scores 2.1/5, falling 0.41 points below the category average—a consideration for those sensitive to how their own voice sounds while wearing hearing aids. Feedback handling measures 3.8/5, which is solid in absolute terms, though it sits 0.74 points below the typically strong OTC category average for this metric. The Cearvol Wave is best suited for budget-conscious consumers who prioritize music streaming quality and want solid speech clarity in quieter settings. Those who frequently encounter noisy environments or are particularly sensitive to own-voice quality may want to consider alternatives.

Eargo 5
The Eargo 5 is a premium-priced OTC hearing aid ($1,450) featuring an invisible-in-ear design with rechargeable batteries. In our lab testing, it earned a B grade with a SoundScore of 3.6/5, placing it in the top 52% of the OTC hearing aid category. This device demonstrates solid performance for speech understanding in quiet environments, scoring 3.5/5—0.75 points above the category average of 2.79/5. Own-voice comfort also measures above average at 2.8/5 (+0.29 vs category), though this remains mixed in absolute terms. Feedback handling is strong at 4.2/5, providing reliable stability during wear. However, the Eargo 5 shows notable limitations in other areas. Speech in noise performance is low at 1.4/5, slightly below the category average. Most significantly, music streaming scored 0.0/5, falling 1.92 points below the category average—this device does not support audio streaming functionality. The invisible-in-ear form factor appeals to users prioritizing discretion, and the closed sleeve coupling remains consistent between initial and tuned fits. Tuning provided modest improvement, moving from a normalized Initial Score of 3.5/5 to a Tuned Score of 3.7/5. Given its premium price point, consumers may want to compare against alternatives like the Sony CRE-C10 or Nuance Audio Glasses, which offer similar or better sound performance at lower price points. The Eargo 5 is best suited for users who prioritize cosmetic discretion and primarily need help with speech in quieter settings.
