Planar magnetic drivers with expansive soundstage

The HE-400S are a full size, planar magnetic headphone from HiFiMAN. They provide a fine attention to detail, a spacious soundstage, upgraded bass response, and exceptional clarity. They are compatible for use with any smartphone, device, or portable audio player. The HE-400S feature planar magnetic drivers that include conductive layers over most of the diaphragm. They provide high quality audio without the sound distortion that occurs in other dynamic headphones. Most dynamic headphones in their class include conductors that vibrate only in limited areas of the diaphragm. This results in a large portion of the diaphragm not being driven by those conductors. The HE-400S are specially designed to effectively utilize all their available space on the soundstage without producing natural distortion or unwanted noise. They have a lightweight, comfortable headband and extra soft earpads making them perfect for hours of extended use.

The HiFiMAN HE-400s headphones have silver earcups and brackets with black perforated grills covering the driver backs. The earpads feature a comfortable black velour covering and the headband consists of a soft The ear pads themselves are covered in a very comfortable black velour with the head band being made of a soft perforated vinyl material. They feature sturdy, rugged construction with a durable black metal support frame. While they are extremely tough and durable, they are lightweight weighing in at only 12 ounces. The HE-400S also include new 2.5mm plug-in connectors to attach the cable to the earcups. These replace the screw-on type connectors that have been used on older HiFiMAN model headphones as an added upgrade. They also come standard with a 1/4 inch headphones adapter plug.
