How We Test

The Sennheiser Conversation Clear Plus is a premium amplification product that earns an A grade with a SoundScore of 4.1/5 in our lab testing, ranking #4 among 8 tested amplification devices. At $850, it positions itself at the higher end of the amplifier market but delivers performance that justifies the investment for the right user.

This device excels in specific areas where many amplifiers struggle. Music streaming quality is excellent at 5.0/5, measuring 3.84 points above the category average—a standout result for consumers who prioritize audio fidelity when streaming from their phones. Speech understanding in noisy environments also performs well at 3.7/5, scoring 2.90 points above the category average, making it a solid choice for challenging listening situations like restaurants or group conversations.

However, the Conversation Clear Plus shows a significant weakness in own-voice comfort, scoring just 0.6/5—well below the category average by 2.04 points. Users sensitive to how their own voice sounds while wearing hearing devices should be aware of this limitation. Speech in quiet environments scores 2.5/5, which is above the category average but only mixed in absolute terms.

The device features rechargeable batteries and streaming compatibility with both iPhone and Android devices, along with hands-free functionality. It's best suited for tech-savvy users who prioritize streaming quality and need help hearing in noisy environments, but who can tolerate some own-voice occlusion effects. Those seeking alternatives at lower price points might consider devices like the Jabra Enhance Plus, though with different performance trade-offs.

Fit Performance

Initial and Tuned Results for the Conversation Clear Plus

We tested this Sennheiser amplifier in both its out-of-box initial configuration and after applying the manufacturer's tuning process. The summaries below show how each fit condition performed against prescriptive amplification targets.

Lab Test Summary

In our initial fit testing with closed dome coupling, the Conversation Clear Plus achieved a normalized Initial Score of 4.1/5. The device delivered excellent results for music streaming (5.0/5) and feedback handling (5.0/5) right out of the box. Speech in noise performed solidly at 3.6/5, well above the category average. Speech in quiet measured 2.0/5, and own-voice comfort was low at 0.6/5, indicating noticeable occlusion effects during initial use that users should anticipate.

What is HearAdvisor's Initial Fit?

The Initial Fit approximates the most likely settings and eartips for a typical moderate hearing loss. Results are measured across the same 72 acoustic scenes in our custom-built lab, then scored on a 5-star scale using an auditory model.
