HearingAssist Control vs Sennheiser Conversation Clear Plus

The HearingAssist Control is a behind-the-ear OTC hearing aid priced at $549, earning a B grade with a SoundScore of 3.3/5 in our lab testing. This places it in the lower portion of the OTC category, ranking #51 of 65 devices tested. In our testing, the Control demonstrates notable strengths in speech performance. Speech in quiet scores 0.59 points above the category average at 3.4/5, representing solid absolute performance. Speech in noise comes in at 2.0/5—above the category average by 0.56 points, though only mixed in absolute terms. Feedback handling is excellent at 5.0/5, meaning the device remained stable without audible squealing during our standardized challenge tests. The device shows significant weaknesses in other areas. Music streaming scored 0.0/5, which is 1.92 points below the category average and indicates this device does not support or perform well with phone audio streaming. Own-voice comfort is also below average at 2.1/5 (0.41 points below category average), which may be noticeable during extended conversations. The HearingAssist Control may suit users who prioritize speech clarity over streaming functionality and who don't require premium sound quality across all use cases. However, buyers in this price range should note that several competitors—including the Yeasound RIC800 and Sony CRE-E10—deliver substantially higher overall scores. Those seeking similar speech performance at a lower cost may also consider the iHear MatriX.

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.
