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.

Eargo 8

The Eargo 8 is a premium-priced OTC hearing aid featuring an invisible-in-ear design with rechargeable batteries, priced at $2,399. In our lab testing, it earned a B grade with a SoundScore of 3.4/5, placing it in the top 71% of the OTC Hearing Aid category. Sound performance presents a mixed picture. The Eargo 8 delivers solid speech-in-quiet performance at 3.1/5, scoring 0.27 points above the category average—making it a reasonable choice for conversational settings without background noise. Own-voice comfort is another strength, measuring 0.69 points above average at 3.2/5, which may appeal to users who are sensitive to hearing their own voice through hearing aids. Feedback handling is strong in absolute terms at 4.2/5, though slightly below the category average. However, the device shows notable weaknesses in challenging listening environments. Speech-in-noise performance is low at 1.2/5, falling 0.27 points below the category average—users who frequently encounter noisy restaurants, busy offices, or social gatherings may find this limiting. Music streaming scored 0.0/5, significantly below the category average, making this device unsuitable for users who prioritize audio entertainment through their hearing aids. The Eargo 8 is best suited for users who prioritize discreet, invisible-in-ear styling and primarily need assistance in quieter conversational settings. However, at this premium price point, buyers should be aware that similarly-priced alternatives and even some lower-cost options may offer comparable or better overall sound performance.
