Our take on the HiFiMAN HE-400 by Crutchfield's David Brown
Discover the planar advantage with HiFiMAN
The headphone industry has many newcomers, but few have distinguished themselves as much as HiFiMAN. They have wowed listeners with their planar magnetic driver design, which produces warm, dynamic sound across a wide soundstage. The HE-400 is their entry-level planar headphone, letting you experience the planar advantage at an affordable price.
Unlike dynamic drivers used in most headphones and speakers, planar drivers use thin flexible diaphragms with voice coils etched onto their surface rather than a voice coil attached to a cone. This exceptionally lightweight structure uses a large driver surface area to reproduce your music with openness and detail that are difficult to achieve with conventional designs. Relatively efficient for planar driver headphones, the HE-400 can be driven by a portable music player. But you'll want to pair them with a good headphone amp to make them sound their best.
Soft earpads and a cushioned headband allow you to enjoy the HE-400's tight bass and smooth treble for hours at a time. The high-quality cable another hallmark of HiFiMAN's dedication to great sound attaches to each earcup, making it easy to swap it out for a custom or aftermarket cord.Looking for a great-sounding portable music player?
