Product Description

Hi-Fi Man HE400S headphones (genuine with full warranty) are amazing value planar magnetic headphones. Easy to drive, they are ideal for portable and home use and are one of the highest efficiency planar headphones in the world. These sound stunning with your smartphone, portable music player, or amplifier at home.

Superb Hi-Fi Quality

The HE400 Planar Magnetic headphones deliver the realistic clarity, detail, extended bass and wide sound stage that audiophiles have come to love and expect from HiFi Man.

Hours of Comfort

An Innovative headband and specially designed hybrid earpads made of leather and velour, the headphones offer optimum comfort allowing you to enjoy your music for hours on end. Weighing only 350g, the incredibly lightweight HE400S eliminates the dicomfort and fatigue associated with extended listening periods.

Planar Magnetic Headphones

While dynamic headphones use conductors that vibrate in limited areas of the diaphragm, resulting in a large portion of the diaphragm not being directly driven by those conductors, Planar headphones have conductive layers over almost all of the diaphragm. This allows the diaphragm to be evenly driven by these conductors for significantly lower distortion than conventional headphones.

    Right, why did I buy these ?

    I had Sennheiser HD650 and AKG 701, and found that being driven by either my Musical Fidelity HPAP or Lehmann black cube linear amplifiers, the 650’s were too dark & the AKG too bright. The AKG had more detail, and the 650 were more laid back. I wanted something in between. I’m not a bass head, but I like the bass to be follow-able and taught.

    So, I purchased these HE400s, and have by my reckoning, got the perfect balance between the 650 & 701’s.

    Still great detail, (like AKG) and nice taught bass, (unlike 650) and fairly neutral across the spectrum, these are about the same level of bass as the 650 but oh so much nicer as the midrange and highs are not at all veiled, like the 650, so you have better depth and greater openness of instruments, and as I said the perfect match for my listening. They are far better in the lower end of bass than the AKG but still retain the detail and openness.

    Soundstage is better than 650, and as good as 701, the airiness is good, better than 650 but and again about the same as 701, but as a whole package the 400s are definite keepers and these are excellent value planar magnetic phones.

    I also own the Oppo PM-3 which is a closed back planer, for travel which again is better than 650 and 701, but due to its closed back, separation, soundstage and airiness suffer a little bit, but again for the price and its more designated requirement they are excellent value planar phones.

    But, I drive the HE400s with good amplification, and only red book cd as a source from a Cyrus CDi with solid silver I/C’s, so these at £219, amp at £649, CDi £950 and I/C’s £400, is probably more than most will ever contemplate, but I’m a firm believer that speakers and headphones have to have their nuts driven off to get the best out of them, and will outperform better headphones with inferior sources. (Two monoblock power amps 550/wpc drive my Spendor D7 speakers and they sing.)

    For my set up, the price of £219 is a bargain for these very fine performing headphones, very highly recommended with good sources.

    NOTE: Don’t listen to the HE400s until they’ve had about 50 hours run-in, or you’ll probably think you’ve wasted your money (tinny and brash), they become sweet after 100 hours and can be further enhanced by slightly deeper bass (no alteration of accuracy) by buying the focus earpads, which then makes them an absolute bargain
