Manufacturer's Description:

We did some research on defective drivers, and noticed poor contact between metal trace and frame. We reinforce the contact, then problem solved. We run-in the fixed drivers for 100+ hrs and don't have the problem again. We will keep run-in the fixed drivers until 200+ hrs. Hopefully we will eluminate the problem from 2nd batch.


For all HE-400 shipped on Jan, 2012, we will provide 3 year replacement policy.

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.
