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.

Signia Silk Charge&Go IX
The Signia Silk Charge&Go IX is a premium prescription hearing aid featuring an invisible-in-ear design, currently available at $3,298. In HearAdvisor's lab testing, it earned a B grade with a SoundScore of 3.7/5, ranking #32 of 39 prescription hearing aids tested. This device demonstrates a notable strength in speech clarity for quiet environments, scoring an excellent 4.6/5—well above the category average by 1.22 points. Speech in noise performance is mixed at 2.2/5, though this still edges slightly above the category average. Feedback handling is strong at 4.3/5, providing reliable stability during typical wear, even if it falls just below the category average. The Silk Charge&Go IX has significant limitations to consider. Own-voice comfort scores low at 1.5/5, falling 1.20 points below the category average—a trade-off that may relate to the invisible form factor. Most notably, the device does not support music streaming, scoring 0.0/5 in that metric, which is 2.76 points below the category average. At this premium price point, several competitors deliver substantially higher overall performance, including the Phonak Sphere Infinio (4.98/5) and Oticon Intent (4.83/5). The Silk Charge&Go IX is best suited for users who prioritize an invisible, rechargeable design and primarily need clear speech understanding in quieter settings, while having minimal need for streaming audio content.
