Sennheiser Conversation Clear Plus Hero
SennheiserSoundScore 4.0Grade A

Sennheiser Conversation Clear Plus

The Sennheiser Conversation Clear Plus is a premium amplification product priced at $850, earning an A grade with a SoundScore of 4.0/5 in our lab testing. This visible-in-ear device ranks #1 among the 8 amplification products we've tested, performing well above the category average of 3.24/5. In our testing, the Conversation Clear Plus delivered standout performance in music streaming and feedback handling, both scoring an excellent 5.0/5. Speech-in-noise performance was solid at 3.1/5, measuring 1.74 points above the category average—a notable advantage for an amplification product. Speech-in-quiet scored 2.6/5, which is above the category average but mixed in absolute terms. The device's primary weakness is own-voice comfort, scoring just 0.6/5—2.04 points below the category average. Users who are sensitive to hearing their own voice amplified may find this challenging. The device supports both iPhone and Android streaming, offers rechargeable batteries, and includes hands-free functionality. The Conversation Clear Plus is best suited for consumers who prioritize exceptional music streaming quality and solid performance in noisy environments, and who can tolerate some own-voice occlusion. It has earned HearAdvisor's Expert's Choice Award in both 2023 and 2024. Those seeking similar sound quality at a lower price point may also consider alternatives like the Apple AirPods Pro 2.

Sony CRE-C20 Hero
SonySoundScore 3.5Grade B

Sony CRE-C20

The Sony CRE-C20 is a mid-priced OTC hearing aid with an invisible-in-ear design, available for $999. In our lab testing, it earned a B grade with a SoundScore of 3.5/5, ranking #37 of 65 OTC hearing aids tested. This device shows a notable split in performance. Speech clarity is a clear strength—speech in quiet scores 4.1/5, which is 1.33 points above the category average, and speech in noise scores 2.7/5, sitting 1.24 points above average despite being only mixed in absolute terms. These results suggest the CRE-C20 prioritizes conversational intelligibility in its tuning approach. However, the device has significant limitations. Music streaming scored 0.0/5, falling 1.92 points below the category average—a notable weakness for users who want to stream audio. Feedback handling is solid at 3.9/5, though it sits 0.64 points below the category average of 4.54/5. Own voice comfort is mixed at 2.9/5, slightly above the category average. The CRE-C20 responds well to adjustment, with the normalized score improving from 3.3/5 at initial fit to 4.2/5 when tuned—a 0.9-point gain. Buyers focused primarily on speech understanding in conversations may find value here, but those wanting music streaming or seeking the strongest overall OTC performance should note that several competitors in this price range, including the Sony CRE-E10 at 4.66/5, scored higher in our testing.
