At the upcoming CES in Las Vegas in January, HiFiMAN will be introducing an exciting new planar magnetic model, HE-400.
Until CES close on January 13, we are offering HE-400 at special pre-order pricing of $349.  Save $50 by ordering by Monday January 13. We will do shipping on Jan 15th, 2012.
 
 
What makes HE-400 special is:
 
1)      it is 92.5DB efficient so it can be driven by virtually anything including an iPod.
2)      It has the familiar HiFiMAN sonic signature which means it is very detailed yet warm
3)      It is only $399 MSRP. We price it at such a price because we finally figure out a way to mass produce hi-end sound quality planar driver headphones in a much easier way than before. 
 
Spec
 
Sensitivity: 92.5 DB
Impedance: 35 Ohm
Weight: about 440 gram or 14.5 Oz
Frequency response: 20Hz to 35 KHz
 
 
Accessories
OFC copper headphone cable (3 meter or 10 Feet)
 

Are there any other accessories included with the headphones like Box and spare Ear Pads? 
 
I'd also be interested to find out how it compares to the HE-500.

I just received notice that mine have shipped -- so these guys are right on schedule.  I did order early FWIW.
