Meta Ray-Ban Glasses (Gen 2)

The Meta Ray-Ban Glasses (Gen 2) is a budget-priced amplification product at $375 that earned a B grade with a SoundScore of 3.8/5 in our lab testing. This hearing glasses device ranks #2 of 8 in the Amplification Product category, placing it in the top 13% of its class. This device excels in areas that complement its lifestyle-focused design. Music streaming performance is strong at 4.3/5, scoring 3.14 points above the category average—a standout result for amplification products. Own-voice comfort is excellent at 4.7/5, measuring 2.06 points above category average, meaning users should experience minimal occlusion or unnatural sound when speaking. However, core speech amplification metrics reveal limitations. Speech in quiet scores 2.7/5, which is 0.62 points above the category average but only mixed in absolute terms. Speech in noise is low at 1.6/5, though still 0.25 points above the category average of 1.37/5. Feedback handling is a notable weakness at 1.9/5, falling 2.38 points below the category average—users may experience more whistling or instability than with other amplification devices. The Meta Ray-Ban Glasses (Gen 2) is best suited for consumers who prioritize music streaming quality and comfortable own-voice perception over maximum speech clarity. Those seeking primary amplification for conversation in challenging listening environments may want to consider alternatives with stronger speech performance.

This device delivers exceptional speech performance in our testing. Speech in noise scored an excellent 4.5/5, a remarkable 2.55 points above the category average of 1.96/5—one of the largest margins we've measured in this critical metric. Speech in quiet also performed strongly at 4.3/5, exceeding the category average by 1.00 point. These results suggest the Sphere Infinio Ultra prioritizes speech clarity across challenging listening environments. Music streaming quality is solid at 3.3/5, sitting 0.66 points above the category average.

The Sphere Infinio Ultra is best suited for users who prioritize speech understanding, particularly in noisy environments, and who are prepared to invest in premium technology. Those seeking the highest feedback stability or improved own-voice comfort may want to compare alternatives, though this device's speech performance stands out as a category leader.
