HiFiMan HE-400i measurements
« on: September 03, 2014, 05:07:28 AM »
A big thanks to uncola for sending these here.
  • Remarkable consistency for an ortho.
  • Low distortion
  • Bass not as taut as original HE-400, but better than HE-500.
  • "Fun" U-shaped signature without overbloated bass.
  • A bit of treble peakage there at 9k
Overall a fine effort following in the footsteps and in the spirit of the original HE-400. The midrange distortion (audible) of the original HE-400 has been corrected. The treble bump of the original HE-400 is moved down a few thousand Hz from the mid/high treble to the mid treble.

BTW - the packaging and the box are awesome. So much improved from the cheap box of the original HE-400. Smells nice too.


Design of the headphone is similar to HE-560, but has plastic cups instead. I actually prefer the shiney plastic cups to the veneer of the HE-560.

Looks like the same 4k bump (as the HE560) is still hanging out there. This time it's accompanied by another peak an octave above. I'm guessing you're not averaging responses anymore as the high treble looks to have a well defined curve.

Any comparisons between the 400i and the LCD 2?

The LCD-2 has more bass power and continues / flattens after the treble roll-off, whereas the HE-400i comes back with a mid-treble emphasis. The new HFMs (400i and 560) are a little bit softer with bass impact, but overall less muddy compared to the HE-500 and maybe less veiled / thick as the LCD-2.

If you can get past the LCD-2's dark tilt, the LCD-2 is really in another class of headphone compared to the HE-400i. As it should for the price differential.

The HE400is I have on hand appear to sound different in the treble region, mine is also dipped at 5kHz, but then rises quickly and is bumpy but not a huge defined peak, between 7kHz and 12kHz.

Marv would you say there is something up with upper treble (past 10kHz) measurement in your current setup? I know you said the HE560 measurements' massive upper treble rolloff was a measurement artifact, is that also the case here?

yes, it's possible past 10k not accurate. That dip may in fact be a peak.

CSD's show definite peak at 9k and possibly another one at 11-12k (the dip which turns into ringing). The ~9k peak is very evident from listening. I do wonder if this sample is not representative of the others.

Thank you a lot for the measurement, was waiting for them for quite some time!

It seems that HE-500 are more neutral, right? (Especially with jerg pads...)
