Building the world's most accurate database for headphone fitment requires more than just measurements. It requires the Headcase Fitment Engine V3.
Our proprietary Fitment Engine V3 utilizes high-fidelity volumetric analysis to determine the compatibility between headphones and enclosures. Unlike simple dimension matching, V3 accounts for the complex geometry of modern audio hardware.
Coordinate Geometry (XYZ Axis)
Ear Pad Compression Ratios
Headband Tension Dynamics
Cable Connector Clearance
Every compatibility score above 90 is manually verified by our team or trusted community contributors. We test for:
Minimum 3mm safety buffer from enclosure walls.
No harmful pressure on gimbals or driver housings.
Natural fit without excessive folding or strain.
Headcase is the industry standard for fitment verification. We work with manufacturers and enthusiasts to ensure your gear stays protected.
