Planar Magnetic Headphones for the Masses

One of the highest efficiency planar phones in the world! HIFIMAN’s newest HE400S sounds terrific on your smartphone or most any portable audio device. HE400S delivers all the lifelike clarity, detail, extended bass and wide sound stage that audiophiles have come to expect from HIFIMAN.



Long Hours of Comfortable Listening

Innovative adjustable headband and specially designed ear pads allow you to enjoy your music for hours on end. The headband is made from breathable, perforated leather with multiple adjustments. The large earpads are made from velvet, making long listening sessions a breeze. Combining these features with the HE400S' lightweight at only 12.34 oz (350 g), makes these some of the most comfortable planar magnetic headphones on the market today.



Why Choose A Dynamic Headphone…When You Can have Planar?

Dynamic headphones utilize conductors that vibrate in limited areas of the diaphragm. Result is that a large percentage of the diaphragm cannot be directly driven by those conductors. Planar headphones have conductive layers over almost all of the diaphragm. Evenly driven by these conductors, result is significantly lower distortion than conventional dynamic headphones.




General Features:

  • Wired Lightweight Stereo Headphones
  • Over-ear design
  • Large Planar Magnetic speaker driver produces amazingly clear sound
  • Detachable cable for easy storage
  • Adjustable headband for comfortable listening sessions
  • Gold-plated, corrosion-resistant stereo jack
  • NOTE: With this remarkable sensitivity, HE400S does not require a large amplifier. In fact, best results will be achieved if you use this particular model with a high quality amp of moderate power. We recommend not pairing HE400S with an amp that has an output of 500mW per channel or greater. If HE400S is paired with too much power, distortion or damage can result so choose high quality and moderate power. It sounds terrific driven right from a smartphone.

Great Headphones at a Great Price!

These headphones are amazing for the value. At this price it's impossible to get a pair of better sounding headphones. The highs, mids, and lows are crystal clear with very low distortion at even the highest volumes when running them off of an amp. The bass, I found to be lacking a bit when you get to the lower frequencies, but even then, they are far superior to any other headphones in this price range. I listen to all types of music from, rap and hip hop, to rock and reggae. These headphones were able to surpass my expectations for every single one of these genres. The comfort level of these headphones is also very good. I am able to listen to these headphones for hours on end with no listening fatigue at all. The only con that I found with these headphones is that they have a rather long break in period. The manufacturer recommends 150 hours of playtime for these headphones to be broken in. While these headphones sound very good without being broken in, the difference in sound quality once they are broken in is night and day which makes me wish the break in time was a little quicker. Other than that, this is a great sounding headphone that is more than worth the price.
