Autiphon U0 Series vs Meta Ray-Ban Glasses (Gen 2)
Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

Autiphon U0 Series
The Autiphon U0 Series is a budget amplification product priced at $99, earning a C grade with a SoundScore of 2.9/5 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 a mixed performance profile. Its standout strength is excellent feedback handling, scoring a perfect 5.0/5—well above the category average by 0.72 points. This means users are unlikely to experience whistling or squealing during normal use. Speech in quiet environments scores 2.3/5, which is 0.22 points above the category average, though still 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—meaning challenging listening environments like restaurants or gatherings will be difficult. Music streaming capability is essentially non-functional, scoring 0.0/5 and sitting 1.16 points below category average. The Autiphon U0 Series is best suited for budget-conscious users who primarily need basic amplification in quieter settings and prioritize freedom from feedback issues. Those who frequently encounter noisy environments or want to stream music should consider alternatives. At this price point, the HSKLock Hearing Aid offers slightly higher overall performance at 2.98/5.

Meta Ray-Ban Glasses (Gen 2)
The Meta Ray-Ban Glasses (Gen 2) is a budget-priced amplification product in the hearing glasses style, earning a B grade with a SoundScore of 3.8/5 in our lab testing. Priced at $375, this device ranks #2 of 8 in the Amplification Product category. In our testing, this product demonstrated exceptional strengths in music streaming quality, scoring 4.3/5—a remarkable 3.14 points above the category average. Own-voice comfort was equally impressive at 4.7/5, exceeding the category average by over 2 points. These results suggest Meta has prioritized the audio experience that their glasses are known for, delivering strong fidelity for streamed content and minimal occlusion-related discomfort. However, speech performance presents a more mixed picture. Speech in quiet scored 2.7/5, which is above the category average by 0.62 points but only mixed in absolute terms. Speech in noise measured 1.6/5—still above average for the category, but low overall. The most notable weakness is feedback handling at 1.9/5, falling 2.38 points below the category average. The Meta Ray-Ban Glasses (Gen 2) are best suited for users who prioritize music streaming quality and comfort over maximum speech clarity. Those seeking amplification primarily for challenging listening environments may want to consider alternatives with stronger speech-in-noise performance.
