Autiphon U0 Series

The Autiphon U0 Series is a budget amplification product available at $99, earning a B grade with a SoundScore of 3.0/5 in HearAdvisor's lab testing. This visible-in-ear device ranks #6 of 8 amplification products tested, placing it in the top 63% of its category. In our testing, the U0 Series demonstrates excellent feedback handling at 5.0/5, scoring 0.72 points above the category average. This means users can expect stable performance without the whistling issues that plague some amplifiers. Speech in quiet environments scores 2.3/5—above the category average by 0.22 points, though only mixed in absolute terms. The device shows notable limitations in other areas. Speech in noise performance is low at 1.0/5, falling 0.37 points below the category average, which may make challenging listening environments difficult. Music streaming is the weakest area at 0.0/5, coming in 1.16 points below category average—users seeking audio streaming functionality should look elsewhere. The Autiphon U0 Series is best suited for budget-conscious consumers who primarily need basic amplification in quieter settings and prioritize reliable, feedback-free operation over advanced features. The rechargeable batteries add convenience at this price point. However, those who frequently encounter noisy environments or want to stream music should consider alternatives despite the higher cost.

Resound Nexia Hero
ResoundSoundGrade A

Resound Nexia

The Resound Nexia is a premium behind-the-ear prescription hearing aid released in 2023, priced at $4,298. In HearAdvisor's lab testing, it earned an A grade with a SoundScore of 4.0/5, ranking #26 of 36 devices in the Prescription Hearing Aid category. The Nexia demonstrates clear strengths in specific performance areas. Feedback handling is excellent at 5.0/5, scoring 0.29 points above the category average—meaning users can expect reliable stability without whistling during typical daily activities. Own-voice comfort is also a highlight at 3.6/5, measuring 0.85 points above average, which may appeal to those bothered by their voice sounding hollow or boomy in other devices. However, the Nexia shows meaningful limitations in challenging listening environments. Speech in noise performance is low at 1.0/5, falling 0.96 points below the category average of 1.96/5. Speech in quiet scores 3.2/5—solid in absolute terms, though 0.11 points below the category average. Music streaming is mixed at 2.8/5, slightly above average but not a standout. At this price point, several alternatives in the same range deliver stronger overall performance, including the Phonak Sphere Infinio and Oticon Intent. The Nexia may be best suited for users who prioritize own-voice comfort and feedback-free performance over speech clarity in noisy environments, and who value the Resound ecosystem's connectivity features including iPhone and Android streaming with hands-free capability.
