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.

Linner Nova Deluxe
The Linner Nova Deluxe is a budget-priced OTC hearing aid with a visible in-ear style, earning a B grade with a SoundScore of 3.3/5 in our lab testing. At $299, it sits in the entry-level price tier for the OTC category. In our standardized testing, the Nova Deluxe showed mixed results across performance metrics. Its standout strength is excellent feedback handling, scoring a perfect 5.0/5—0.46 points above the category average. This means users can expect stable performance without whistling during typical daily activities. Speech clarity in quiet environments scored 2.8/5, matching the category average, while speech in noise measured 1.4/5, slightly below average at -0.06 points. The device has notable limitations in comfort and entertainment features. Own-voice comfort scored just 0.5/5, falling 2.01 points below the category average—users may notice their voice sounds unnatural or boomy. Music streaming scored 0.0/5, which is 1.92 points below average, indicating this device is not suitable for those who prioritize audio entertainment through their hearing aids. The Linner Nova Deluxe ranks #53 of 65 OTC hearing aids tested. Buyers seeking better overall performance in this price range may want to consider alternatives like the Elehear Beyond (4.34/5) or Apple AirPods Pro 2 (4.04/5). However, for users primarily focused on speech clarity in quieter settings who don't need streaming capabilities, the Nova Deluxe offers solid feedback stability at an accessible price point.
