When sound waves bounce off surrounding surfaces, the scattering that results often causes music to sound noisy and distorted. But the Panasonic SC-HC28 Slim Stylish Compact Micro System comes with noise-canceling technology. Using digital signal processing, it reduces the scattering so your sound is clean and pure, with significantly less distortion.
