EarCentric EX2 vs Nuance Audio Glasses
Side-by-side HearAdvisor lab results with SoundGrades, expert pick badges, and the same visualizations we use in product reviews.

EarCentric EX2
The EarCentric EX2 is a behind-the-ear prescription hearing aid priced at $218, positioning it as a budget-friendly option in the prescription category. In HearAdvisor's lab testing, it earned a C grade with a SoundScore of 2.7/5, ranking #35 of 39 prescription hearing aids tested. This 2021 release demonstrates mixed performance across key metrics. Its standout strength is feedback handling, scoring an excellent 4.7/5—essentially matching the category average and indicating reliable stability during movement. However, speech performance is a significant weakness: speech in quiet scores just 1.0/5 (2.40 points below the category average of 3.40), and speech in noise scores 1.0/5 (1.11 points below average). These low absolute scores suggest limited audibility enhancement in our standardized test conditions. Own-voice comfort scores 2.3/5, which is mixed in absolute terms and 0.40 points below the category average. Music streaming scored 0.0/5, indicating this device is not suited for audio entertainment purposes. The EarCentric EX2 may appeal to budget-conscious consumers who prioritize cost over performance, but alternatives exist at similar or lower price points with stronger test results. The RxEars Rxi, available in the same price range, scored 4.07/5 in our testing. Consumers seeking entry-level amplification should weigh the significant speech clarity limitations against the low purchase price.

Nuance Audio Glasses
The Nuance Audio Glasses are a premium OTC hearing aid priced at $1,200, featuring an innovative hearing glasses form factor that integrates amplification technology directly into eyewear. In HearAdvisor's lab testing, they earned a B grade with a SoundScore of 3.9/5, ranking #20 among 65 OTC hearing aids tested. This unique design delivers standout performance in own-voice comfort, scoring an excellent 4.7/5—well above the category average by 2.19 points. Speech clarity in quiet environments is also a strength at 3.8/5, exceeding the category average by 1.05 points. Speech understanding in noisy situations scores 2.3/5, which is above the category average but only mixed in absolute terms. The glasses form factor comes with notable trade-offs. Music streaming scored 0.0/5, falling 1.92 points below the category average—a significant limitation for users who want to stream audio. Feedback handling at 2.0/5 is 2.54 points below the category average, indicating potential stability challenges in certain situations. The Nuance Audio Glasses are best suited for consumers who prioritize discretion and want hearing amplification without a traditional in-ear device. The excellent own-voice comfort makes them appealing for those sensitive to the "plugged up" feeling of conventional hearing aids. However, buyers seeking music streaming functionality or who are in the same price range should note that alternatives like the Lucid Tala (4.61/5) or Audicus Omni 2 (4.59/5) offer stronger overall sound performance.
