Meta Ray-Ban Glasses (Gen 2) vs Sontro Soundwave
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.

Sontro Soundwave
The Sontro Soundwave is a mid-priced OTC hearing aid that earns a B grade with a SoundScore of 3.0/5 in our lab testing. At $849, this behind-the-ear device uses disposable batteries and sits in the lower tier of OTC performance, ranking #61 of 65 devices in its category. The Soundwave's strongest attribute is own-voice comfort, scoring 3.6/5—a solid result that sits 1.09 points above the OTC category average. This makes it relatively comfortable for wearers who are sensitive to hearing their own voice sound unnatural or boomy. However, other performance areas present significant limitations. Speech clarity scores are below average in both quiet and noisy environments. Speech in quiet scores 2.7/5 (0.12 points below average), while speech in noise drops to 1.2/5 (0.28 points below average). Feedback handling is a notable weakness at 2.5/5, falling 2.04 points below the category average of 4.54/5. Perhaps most limiting is the music streaming score of 0.0/5, indicating this device does not support phone audio streaming—a feature many competitors in this price range offer. Consumers prioritizing own-voice comfort on a moderate budget may find the Soundwave acceptable, but those seeking strong speech clarity or streaming capability should consider alternatives. Several higher-performing OTC devices are available at similar or lower price points, including options like the Lexie Lumen or HearingAssist Control that deliver comparable or better overall sound quality.
