Headphone Clamp Measurement Rig V1 (Pre-order)

Stop guessing. Start measuring. The CFMR1 is the essential tool for engineers, product developers, and professional reviewers dedicated to optimizing headphone design. Clamp force is a critical factor influencing both long-term comfort and acoustic seal integrity—directly impacting bass response and noise isolation.

Key Features & Benefits:

Easy to Use Online Tool: Use our in-house tool to visualize the Center of pressure and values from each of the 3 high quality load cells!

Laboratory-Grade Accuracy: Utilize a high-precision digital load cell array and robust mechanical design to deliver repeatable and reliable clamp force measurements, ensuring consistency across your production line or product reviews.

True-to-Life Simulation: The rig's adjustable geometry mimics the average human head shape and size, providing a realistic measurement that correlates directly to real-world user experience. Complies with industry standards ITU-T P.58 and IEC 60318-7.

Optimize Comfort: Easily identify the 'sweet spot' for clamp force—strong enough for stability, but gentle enough for all-day listening. Drastically reduce customer returns due to discomfort.

Robust & Easy-to-Use: Constructed from durable, high-quality materials for longevity. The intuitive digital readout and simple adjustment mechanism mean quick setup and streamlined testing protocols.

Universal Compatibility: Designed to accommodate a wide range of headphone types, from lightweight on-ear models to heavy-duty professional over-ear headsets.

Lifetime Support: So long as Capra Audio is in Business we will continue to support this product. If not this project will become open source.
