Essential Info

The HE-400 is one of HiFiMAN's best performing planar magnetic designs. Its impressive 92dB sensitivity is higher than similar designs and can be powered by conventional MP3 players without the use of an additional headphone amplifier. The HE-400 offers impressive frequency response from 20Hz to 35KHz and with all of the dynamics and life like realism that HiFiMAN headphones are famous for. These headphones are quite large and feature over-sized drivers, a high gloss finish, soft leather ear pads already installed on the headphones and a replacement pair of velour ear pads. The back of the headphones feature a open design that are designed to deliver a more genuine listening experience. With the back of the headphones open, ambient noise will infiltrate your headphones while also letting a lot out. The reason for this design is to produce a sound that you may experience if you were listening to your favorite band live which makes these ideal for home or studio use.

Founded by Dr. Fang Bian in 2007, HiFiMAN is widely regarded as one of the leading manufacturers of high performance headphones and portable audio products. They are especially known for its critically-acclaimed Planar-Magnetic headphones that feature state-of-the-art driver technology.

  • More Info

    Planar-Magnetic - Like a standard dynamic headphone, planar magnetic headphones use the magnetic field around a conductor that has electrical current flowing through it to drive the diaphragm. Like an electrostatic driver, the diaphragm of a planar magnetic speaker is a thin sheet of flexible transparent film, but unlike an electrostatic driver, the film has very thin, flat electrical conductors in it. An array of magnets is placed in front of and behind the diaphragm such that the conductors are immersed in a very even field of magnetic flux. When current is passed through the conductors, the magnetic field created by the current flow interacts with the iso-dynamic field created by permanent magnets, causing the conductors, and therefore the diaphragm, to move and generate sound. Because of the conductors, the entire surface area of the diaphragm is used, thus reducing distortion that conventional headphones deliver.
