Through the persistent effort and research on sound, Hemingway’s patented technique found the solution to deal with the magnetic field produced by the electric field. The core of it is the winding of the line in the shape of ‘Z’ with a double-ground at the center. Using this revolutionary technique, we now proudly present our third generation product. You will be able to feel the brand new aspect of sound you have never experienced before and be moved by the surging of overflowing joy, once you hear the sound that Z-core makes.
