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.
