Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

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.

EarCentric EasyCharge
The EarCentric EasyCharge is a budget-priced prescription hearing aid available for $229, earning a C grade with a SoundScore of 2.7/5 in our lab testing. This behind-the-ear rechargeable device ranks #36 of 39 prescription hearing aids tested, placing it in the bottom tier of its category. In our standardized testing, the EasyCharge demonstrates a stark performance divide. Its standout strength is feedback handling, scoring an excellent 5.0/5—slightly above the category average of 4.72. This means users can expect stable performance without whistling during typical daily activities. However, speech clarity metrics tell a different story: speech in quiet scores just 1.0/5, which is 2.40 points below the category average, and speech in noise also scores 1.0/5, falling 1.11 points below average. Music streaming scored 0.0/5, indicating this device is not suitable for audio enjoyment. Own-voice comfort is also limited at 1.9/5, which is 0.80 points below the prescription hearing aid average of 2.70. The device showed no improvement between initial and tuned fitting conditions, with both scoring 2.7/5. At this price point, shoppers should note that alternatives exist with meaningfully better performance. The RxEars Rxi, available in the same price range, scores 4.07/5. The EasyCharge may appeal to those prioritizing feedback-free operation on a tight budget, but its low speech clarity scores suggest significant limitations for everyday conversation.
