Xiaomi | Mi In-Ear Headphones Basic | ZBW4355TY | Built-in microphone | 3.5 mm | Silver

We used the same movable piston design found in all In-Ear Headphones for the sound chamber. Made from strengthened polycarbonate for lighter weight and enhanced comfort, without compromising the structure of the sound chamber. The Mi In-Ear Headphones have cables covered with TPE and made of Kevlar fibers-the same kinds used in bulletproof vests. The high-quality cables feature enhanced strength and resistance to breaking and kinking. Its smooth surface resists tangling.
