Linner Nova Deluxe Hero
LinnerSoundScore 3.3Grade B

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.

Sontro Soundwave Hero
SontroSoundScore 3.0Grade B

Sontro Soundwave

The Sontro Soundwave is a mid-priced OTC hearing aid that earns a B grade with a SoundScore of 3.0/5 in our lab testing. At $849, this behind-the-ear device uses disposable batteries and sits in the lower tier of OTC performance, ranking #61 of 65 devices in its category. The Soundwave's strongest attribute is own-voice comfort, scoring 3.6/5—a solid result that sits 1.09 points above the OTC category average. This makes it relatively comfortable for wearers who are sensitive to hearing their own voice sound unnatural or boomy. However, other performance areas present significant limitations. Speech clarity scores are below average in both quiet and noisy environments. Speech in quiet scores 2.7/5 (0.12 points below average), while speech in noise drops to 1.2/5 (0.28 points below average). Feedback handling is a notable weakness at 2.5/5, falling 2.04 points below the category average of 4.54/5. Perhaps most limiting is the music streaming score of 0.0/5, indicating this device does not support phone audio streaming—a feature many competitors in this price range offer. Consumers prioritizing own-voice comfort on a moderate budget may find the Soundwave acceptable, but those seeking strong speech clarity or streaming capability should consider alternatives. Several higher-performing OTC devices are available at similar or lower price points, including options like the Lexie Lumen or HearingAssist Control that deliver comparable or better overall sound quality.
