Nuance Audio Glasses Hero
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.

Signia Pure C&G IX  Hero
SigniaSoundScore 4.1Grade A

Signia Pure C&G IX

The Signia Pure C&G IX is a premium behind-the-ear prescription hearing aid released in 2023, currently available at $3,298. In HearAdvisor's lab testing, it earned an A grade with a SoundScore of 4.1/5, ranking #22 among 39 prescription hearing aids tested. This device demonstrates notable strengths in speech clarity and feedback control. Speech in quiet scored 4.0/5, which is 0.57 points above the category average—a meaningful advantage for everyday conversations. Feedback handling achieved a perfect 5.0/5, sitting 0.28 points above the already-high category average of 4.72/5. Own-voice comfort also performed well at 3.2/5, exceeding the category average by 0.50 points. Speech in noise presents a more mixed picture. While the 2.2/5 score is technically above the category average by 0.10 points, it remains modest in absolute terms—something to consider if challenging listening environments are a priority. Music streaming scored a solid 3.0/5, sitting 0.24 points above average. The Pure C&G IX features rechargeable batteries and supports streaming to both iPhone and Android devices, including hands-free calling. At this premium price point, competitors like the Phonak Sphere Infinio (4.98/5) and Oticon Intent (4.83/5) achieve higher overall scores. This device may suit those who prioritize clear speech in quieter settings and excellent feedback stability, though buyers seeking stronger noise performance may want to compare alternatives.
