HiFiMan HE 400S Headphones

The Most Affordable Full-size Planar Magnetic Headphone Ever

The HE-400S is HiFiMAN's most affordable full-size planar magnetic headphone. It is also the least expensive planar headphone on the market. But it delivers unequalled performance, styling and comfort in its class.

Weighing in at just over 12 ounces, the HiFiMAN HE-400S is more than 30 percent lighter than comparable headphones, allowing you to comfortably enjoy music for hours on end with minimal listener fatigue. A newly designed ergonomic headband, found in the company's more expensive models, is lighter with an improved pressure pattern that is also key to the phone's exceptional comfort. The headband is designed to accommodate a wide range of head sizes. The new beveled velour ear pads provide both increased comfort and improved sound quality, while the silver ear cups offer a stylish, high-tech look.

Challenging the Status Quo

On the technical side, the HE-400S challenges the status quo with newly-designed single-ended planar magnetic drivers in open-back design. They deliver the clarity, lifelike soundstage, and spatial imaging that HiFiMAN is known for. Sensitivity is increased to 98dB, which allows this efficient headphone to be driven easily with a portable audio device such as an iPod or smartphone. But for ultimate performance, we recommend pairing the HE-400S with a quality amplifier. Impedance of the HE400S is 22 Ohms.

Newly Designed Hybrid Cable

To capture every bit of sonic detail, HiFiMAN designed a brand new hybrid cable, which uses conductors comprised of Oxygen-Free Silver and Oxygen-Free Copper. Also new from HiFiMAN are 2.5mm that plug into the headphone, providing a quick connection as well as making the cable easy to replace or upgrade.

Development of New Planar Magnetic Technology

According to HiFiMAN Founder and President, Dr. Fang Bian, "The original HE-400 was the best-selling, full-size headphone in the company's history and in fact, we still get requests to build more. Over the years, we have invested a lot of resources into planar magnetic technology, ergonomics and industrial design."

"Products like our new HE1000 surely reflect these major investments however the benefits also extend into our most affordable model, the HE400S," reports Dr. Fang Bian. "Light weight, comfort, high sensitivity, and, of course, great sound are all a direct result of our extensive research and development."
