The KAKU Feile KSC-403 are classic white in-ear wired earphones designed for everyday audio use with any device featuring a 3.5mm mini-jack, such as laptops, tablets, or smartphones. They deliver sound across a frequency range of 20 Hz to 20 kHz with an impedance of 32 Ohm, providing a balanced listening experience for music and calls. To make daily use more convenient, these earphones include an integrated microphone and a control button that lets you manage your music and handle incoming calls without reaching for your device. The 1.2-meter cable is designed to be anti-tangle, which helps prevent knots during transport in a bag or pocket.
