NuanceSoundScore 3.9Grade B

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.

SigniaSoundScore 4.3Grade A

Signia Pure Charge&Go MaX

The Signia Pure Charge&Go MaX is a behind-the-ear prescription hearing aid released in 2026 that earns an A grade with a SoundScore of 4.3/5 in HearAdvisor's lab testing. This strong overall performance reflects solid results across key listening scenarios, with particular strengths in own-voice comfort and speech understanding in noisy environments. In our testing, the Pure Charge&Go MaX demonstrated notable advantages over the prescription hearing aid category average. Own-voice comfort scored 1.00 points above the category average at 3.7/5, suggesting effective management of occlusion-related issues that many hearing aid users find bothersome. Speech in noise performance measured 0.65 points above average at 2.8/5—above the category average, but only mixed in absolute terms, indicating room for improvement in the most challenging listening situations. Speech in quiet scored a solid 3.6/5, landing 0.24 points above the category average. Music streaming measured 2.9/5, slightly above average but mixed in absolute terms. Feedback handling scored an excellent 4.6/5 in absolute terms, though this fell 0.12 points below the category average of 4.72/5, reflecting the generally strong feedback control across modern prescription devices. The device showed meaningful improvement from initial to tuned fitting, with the normalized score rising from 4.2/5 to 4.6/5 after professional adjustment. This suggests that working with a hearing care professional to optimize settings can unlock additional performance, particularly for speech understanding. The Pure Charge&Go MaX appears well-suited for users who prioritize natural own-voice quality and improved conversation clarity in moderately noisy settings.
