This places it in the top 23% of the OTC hearing aid category, ranking #16 among 65 tested devices. In our testing, the All-Day Clear Slim demonstrates notable strengths in music streaming, scoring 3.8/5—a solid result that sits 1.88 points above the category average. This makes it one of the stronger performers for users who prioritize audio quality when streaming from their phone. Feedback handling is excellent at 5.0/5, measuring 0.46 points above the category average, meaning users can expect stable performance without whistling during typical daily activities. Speech clarity in quiet environments is solid at 3.6/5, coming in 0.85 points above the category average. However, speech in noise performance is low at 1.5/5, matching the category average—a common limitation across OTC devices. Own-voice comfort scores 1.9/5, which is 0.61 points below the category average, suggesting some users may notice their own voice sounds different or hollow. The All-Day Clear Slim includes rechargeable batteries and supports streaming to both iPhone and Android devices with hands-free functionality. At its price point, alternatives like the Lucid Tala and Audicus Omni 2 offer higher overall scores, though the Sennheiser may appeal to those who value the brand's audio heritage and prioritize music streaming quality over speech-in-noise performance.

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.
