5-Driver IEM With Metal Housing

The latest high-end offering from TFZ, the Series 7 IEM is built with five drivers: four Knowles balanced armatures and a single dynamic driver. Together, these deliver high-resolution sound with ample detail, excellent instrument separation, and strong transient dynamics. The IEM’s textured metal finish gives it a sleek look, and the housings are molded to comfortably fit a variety of ear shapes. Rounding out the package, the high-quality silver-plated OFC cable is detachable and connects via the 0.78-millimeter connector.
