The Sennheiser Conversation Clear Plus delivers exceptional music streaming and feedback handling, making it ideal for audio enthusiasts seeking a premium amplifier.
Top 1% of Amplification ProductOur lab measures five distinct aspects of amplification performance using calibrated equipment and standardized protocols. The scorecard below displays how this Sennheiser device performed on each metric during controlled testing. The purple SoundScore graph is the overall result, and the five graphs after it break it into individual measurements for the selected fit. Each curve shows how scores are spread across all tested hearing aids, and the dot and number mark the score for Sennheiser Conversation Clear Plus.
Every hearing aid is lab-tested in two states — as it sounds out of the box, and after professional tuning. Switch fits to update the five metric graphs below.
How clearly speech comes through in calm, one-on-one surroundings.
Speech understanding against loud background noise — the toughest everyday test.
How natural your own voice sounds while wearing the aids, without a boomy, plugged-up quality.
Sound quality of music streamed to the hearing aids over Bluetooth.
Resistance to the whistling and squealing caused by acoustic feedback.
Lab Assessment
Quality data starts with quality recordings. HearAdvisor worked with GRAS to build a no-compromise front end so every test is repeatable and reliable.
Amplification Data
Insertion gain graphs show how much amplification the device provides across different frequencies compared to prescriptive targets. The visualization below displays our measurements against the fitting rationale for this premium amplifier.
Audio Samples
We captured audio through a head-and-torso simulator to document what the Sennheiser Conversation Clear Plus delivers to the ear canal. Compare the processed samples below against unaided reference recordings.

Test Configuration
Our technicians document the specific settings, equipment, and procedures used during each product evaluation. The notes below detail how we configured this Sennheiser amplifier for measurement.
In its initial fit configuration with closed dome coupling, the Sennheiser Conversation Clear Plus achieves a normalized Initial Score of 4.0/5. Out of the box, speech in quiet scores 2.1/5 and speech in noise scores a solid 3.0/5. The device excels in feedback handling (5.0/5) and music streaming (5.0/5). Own-voice comfort is low at 0.6/5, below the category average. The initial setup delivers strong streaming and stability performance with minimal adjustment required.
After tuning, the Conversation Clear Plus improves to a normalized Tuned Score of 4.2/5, a modest +0.2 point gain. The tuned configuration retains the closed dome coupling. Speech in quiet improves to 2.6/5 and speech in noise reaches 3.1/5. Feedback handling and music streaming remain excellent at 5.0/5 each. Own-voice comfort stays at 0.6/5, indicating that tuning adjustments primarily benefit speech metrics rather than addressing occlusion-related effects.
