I've gotta say, QC issues aside, I have fallen in love with the sound of these for electronic music. Its been 5 days and they keep wow-ing me with their combination of clarity, bass punch, and speed. To my ears, they absolutely destroy the Pro900's, which are at a similar price-point.

I don't think there are a lot of requirements for planar headphones. Even you run-in for 100 hrs, the driver is not hot at all. Don't be too loud though. 

Cool, much thanks Fang! Looking forward to receiving my He-400 in 2-3 wks~

Except for the first hour when the left side was dead totally, mine has been working fine without issue. To prevent channel-imbalance issue from coming up again, I don't dare turning off the amp that these are plugged into LOL!

So I'm happy to report that I haven't any problems since Sunday (after I tightened the inside) with these cans. Today I absolutely fell in love and couldn't stop listening to a mix of electronic / ambient / drone. Everything just sounded so amazing. I am truly in love with these headphones.
 
edit: Oh damn. I just had it cut out twice while cranking some metallica

Get...where exactly? Shipping to some countries could be slower just due to geography / customs.
 
Regardless, just pass a PM to Fang and he should be able to sort it out.

This is some of my messages with Mr. Fang.
 
 
Mr. Nankai.
 
Is it so that you will send Right Driver up to me at Thursday 27?
I must know this to make arangements, thus i´m heading at SEA 1st Feb.
My only reason to buy these was to bring them with me out to the Arctic sea..
 
Hope you can make this Happend.

I will let our US shipping dept ship you a returned HE-400 with both drivers working or at least one side working. We will ship via express mail so that you will receive before 1st Feb. If you got only one side working, you can remove the working driver and put it on yours. If your HE-400 got something wrong later, we will help you got free replacement. 
 
Best,
Fang
 
Now, they are on their way!
 
GOOD service HIFIMAN!!

We have done 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. Very possibly we will eluminate the problem from 2nd batch.
 
 
Normally we do 1 year warranty for HE-400. For all HE-400 shipped on Jan, 2012, we will provide 3 year replacement policy.

Do those of us who pre-ordered but aren't getting ours until after the Chinese New Year get the 3 year warranty?

You've gotta love this guy!

That'd be sweet certainly would make me feel more confident about my purchase.

Doubt it since we won't be going through the trouble of disassembling / soldering etc, but sure we can hope.

Looks like the 2nd batch will only be 1 year.
 
Thats pretty awesome for the first batch of people.   DIY and if your mods fail you can send em back in 3 years time for replacement?

Probably been asked 1000 times, but since the second batch of HE-400's look like they'll turn out nice... So, is it true from people's experience that these don't need that much in way of amping? Are they truly a reasonable headphone at the price, with, say, a FiiO E17?
