Its planar driver gives the low distortion and detail planars are known for, and its high sensitivity lets it run from everyday sources such as phones and tablets.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/hifiman-he400se-headphones-photo-hero.jpg?v=1791361598\" alt=\"HiFiMAN HE400se open-back planar headphones with Stealth Magnets\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003ch3\u003eWhat is a planar headphone?\u003c\/h3\u003e\n\u003cp\u003eDynamic headphones use a voice coil that drives only a limited area of the diaphragm, so much of it is not driven to its full capacity.
