Shaft/head: Silicon Metal core: Aluminum alloy (black anodized) [A new generation of earpieces with a metal core built into the sound guide tube] COREIR aims to achieve spatial expression and sound reproduction close to that of earphones that use metal nozzles. By using aluminum alloy (AL ALLOY) as the metal core material, we offer new possibilities for sound quality. By maintaining the shape of the sound guide tube, the consistency of the sound is also maintained. [Prevents collisions between earphone nozzle and metal core] Colored silicone cushion parts are placed on the metal core to prevent collisions with the nozzle on the earphone side. The cushion parts are colored in four colors, CMYK, to make it easy to distinguish the size. *The compatible size of the tip of the earphone nozzle is φ4.5-5.5mm. *Caution: The metal parts used in this product may come off the silicone parts if strong force is applied.
