Linner Nova Deluxe vs Phonak Sphere Infinio Ultra

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.

Feedback handling measured 4.2/5—strong in absolute terms, though 0.52 points below the category average of 4.72/5. The Sphere Infinio Ultra is best suited for users seeking top-tier speech clarity who prioritize performance in noisy environments and are prepared to invest at the premium price tier.
