Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

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.
Choice

Sennheiser All-Day Clear Slim
The Sennheiser All-Day Clear Slim is a premium OTC behind-the-ear hearing aid priced at $1,499, earning an A grade with a SoundScore of 4.1/5. This places it in the top 23% of OTC hearing aids tested in our lab, ranking #16 among 65 devices in its category. This device excels in areas that reflect Sennheiser's audio heritage. Music streaming quality is a standout strength, scoring 3.8/5—a solid result that's 1.88 points above the OTC category average. Feedback handling is excellent at 5.0/5, meaning users can expect stability without whistling during typical use. Speech in quiet environments also performs well at 3.6/5, sitting 0.85 points above average for the category. However, the All-Day Clear Slim shows limitations in other areas. Speech in noise scores 1.5/5, matching the category average but representing a low absolute score that may challenge users in noisy restaurants or group conversations. Own-voice comfort is below average at 1.9/5, which could affect how natural users sound to themselves during conversation. The All-Day Clear Slim is best suited for consumers who prioritize music streaming and media consumption alongside hearing support, and who spend more time in quieter environments. Those frequently navigating noisy social situations may want to compare against higher-ranked competitors in this price range, such as the Lucid Tala or Audicus Omni 2, which achieve stronger overall scores.
