In planar magnetic headphones, the coil is provided over the entire surface of the diaphragm. As a result, the diaphragm is uniformly driven by magnetic force, so the distortion of planar magnetic headphones is significantly lower compared to conventional dynamic headphones. The HE400se uses a double-sided driver to reproduce a realistic sound field and three-dimensional sound. With a high efficiency of 91dB, it can be driven by a normal headphone amplifier, and can also be used with portable audio players and smartphones. "The HE400se is 30% lighter than other planar magnetic headphones of the same type, so listeners can enjoy music comfortably for hours."
