A PEK+PU composite diaphragm, lightweight voice coil assembly, and N52 magnets support detailed reproduction. Washable velvet earpads and an adjustable metal headband provide a comfortable fit, while a detachable cable with an inline microphone handles music, calls, and gaming.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eLarge drivers for full bass and detail\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eEach earcup houses a 1.97-inch (50mm) dynamic driver designed to deliver a relaxed presentation with robust bass. Its large diaphragm moves air to reproduce low-frequency impact while preserving detail across a wide soundstage.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eA composite diaphragm with controlled movement\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThe diaphragm combines rigid PEK with flexible polyurethane to keep moving weight low while maintaining structural strength. A built-in brass damping ring helps control unwanted diaphragm breakup and reduce distortion, preserving subtle details in voices and instruments.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eA lightweight voice coil assembly\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eA TIL voice coil former combines glass fiber and polyimide for low weight, strength, and resistance to heat. The copper-clad aluminum wire voice coil pairs aluminum’s lightness with copper’s conductivity. Together, these materials help improve driver sensitivity and detail reproduction.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eN52 magnets for responsive sound\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eN52 magnets supply the magnetic force that drives the diaphragm.

This helps reduce pressure buildup within the earcups and supports a broad, natural soundstage with precise imaging. The alloy grilles also keep the outer shell light.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eAngled drivers that follow the ear\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThe drivers sit at an angle to better align with the contours of your ears.
