Lucid Ultra 128

The Lucid Ultra 128 is a premium behind-the-ear prescription hearing aid priced at $5,000, earning an A grade with a SoundScore of 4.4/5 in our lab testing. It ranks #16 of 36 devices in the Prescription Hearing Aid category. Speech performance is a clear strength for the Ultra 128. In our testing, speech in quiet scored a strong 4.3/5, landing 1.03 points above the category average. Speech in noise measured 2.7/5—above the category average by 0.74 points, though mixed in absolute terms. These results suggest the device prioritizes intelligibility in everyday listening situations. The Ultra 128 does show notable weaknesses. Feedback handling scored just 1.7/5, falling 3.01 points below the category average of 4.71/5—a significant gap that prospective buyers should consider. Music streaming measured 2.3/5, slightly below the category average. Own-voice comfort was mixed at 2.9/5, though this sits just above the category norm. The device uses disposable batteries and supports streaming to both iPhone and Android. At this price point, buyers may want to compare against higher-scoring competitors like the Phonak Sphere Infinio (5.0/5) or Oticon Intent (4.85/5). The Lucid Ultra 128 may suit those who prioritize speech clarity in quieter environments and can work with their hearing care provider to manage its feedback limitations.

Sennheiser Conversation Clear Plus

The Sennheiser Conversation Clear Plus is a premium amplification product priced at $850 that earns an A grade with a SoundScore of 4.1/5 in our lab testing. This visible-in-ear device ranks #1 among the 8 amplification products we've tested, earning Expert's Choice Awards in both 2023 and 2024. Streaming and audio quality stand out as exceptional strengths. Music streaming scores an excellent 5.0/5, a remarkable 3.84 points above the category average of 1.16/5. Feedback handling also achieves a perfect 5.0/5, providing excellent stability during use. Speech performance is above the category average, with speech in noise scoring a solid 3.1/5 (+1.74 points vs category) and speech in quiet at 2.6/5 (+0.45 points vs category)—though the latter remains mixed in absolute terms. The primary limitation is own-voice comfort, which scores a low 0.6/5—well below the category average of 2.64/5. This suggests users may notice more occlusion-related effects when speaking. The closed dome coupling used in both initial and tuned configurations contributes to the device's strong feedback performance but does impact own-voice naturalness. The Conversation Clear Plus is best suited for users who prioritize excellent streaming audio quality and stable feedback-free performance over own-voice comfort. Those seeking similar sound quality at a lower price point may consider alternatives like the Apple AirPods Pro 2 or Jabra Enhance Plus. Features include rechargeable batteries, iPhone and Android streaming, and hands-free functionality.
