ALSEYE Replacement Headband Hinge Swivel Connectors (2 Sets) for Audio Technica ATH M40, M40X - Black

Repair Kit for ATH-M40 and M40X

This pack contains two complete hinge-and-swivel sets designed specifically for Audio Technica ATH-M40 and M40X headphones. It restores the folding mechanism when the original plastic brackets crack or loosen. The parts are not compatible with the M40FS or any other model, so verifying the exact headphone designation before ordering is essential.

3D-Printed Fit Without Wire Cutting

Each connector is produced using 3D printing technology, which yields a precise internal geometry that slides onto the existing frame without requiring the internal cables to be severed or re-soldered. The high-quality plastic body presents a smooth, waterproof and dustproof surface that resists the sweat and skin oils that accelerate brittle fracture in the factory parts.

Direct Replacement for Broken OEM Hinges

The kit replaces the original manufacturer hinges that typically fail after repeated folding cycles, returning the headband to its original tension and alignment. The upgrade is worthwhile when the ear cups no longer stay folded or when visible stress lines appear around the pivot points, and it avoids the cost of a full headphone replacement.
