HiFiMAN / HE400se

The HE400se is a lightweight, open-back headphone with a planar magnetic driver that utilizes stealth magnets.

■ Planar Magnetic Headphones
- Compared to conventional dynamic headphones, planar magnetic headphones offer a superior sound experience in terms of sound field and output power. Conventional dynamic headphones only have a coil on a portion of the diaphragm, so they cannot directly vibrate the majority of the diaphragm. In planar magnetic headphones, the coil is provided across the entire surface of the diaphragm. As a result, the diaphragm is driven uniformly by magnetic force, and the distortion of planar magnetic headphones is significantly lower compared to conventional dynamic headphones.

■ Acoustically Transparent Stealth Magnet
- The advanced stealth magnet used in the HE400se is acoustically transparent and aims to dramatically reduce wave diffraction disturbance that degrades the integrity of sound waves. As a result, distortion is reduced, and a purer sound with beautiful harmonics is obtained. Unlike sound waves generated by conventional magnets, the specially shaped stealth magnet allows sound waves to pass freely without causing interference.

■ Easy to Drive
- The HE400se employs a single-ended driver to reproduce a realistic sound field and three-dimensionality. With a high sensitivity of 91dB, it can be driven by a standard headphone amplifier and used with portable audio players and smartphones.

■Lightweight and Comfortable
The HE400se is 30% lighter than similar planar magnetic headphones, allowing listeners to comfortably enjoy music for hours. Furthermore, the newly designed headband and hybrid ear pads enhance comfort and improve sound quality.
