The shell is precision 3D printed in colorful resin finishes and hand‑polished for a dust‑resistant, glossy look. A detachable 0.78mm 2‑pin 4N OFC cable and user‑friendly fit complete the package for versatile stage and studio use.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the bone‑conduction element improve the listening experience?\u003c\/h3\u003e\n\u003cp\u003eThe KB02 integrates a dedicated bone‑conduction unit inside the cavity to transmit vibrational energy through the shell, supplementing what the main dynamic driver produces.
