I sent my old HE400 (made in May I think) with translucent white drivers back because it had a buzzing issue, and the new pair has sandy yellow plastic drivers and seems to sound brighter in the treble.

 

Thanks.

 

 

 

Edit:

 

 

Older driver

 

 

New driver

 

 

Jerg & MattTCG,

 

We recently made some small adjustments on some parts of the driver. 
The new driver you are referring to is the latest version.

Yeah I'm wondering as well, what exact tweaks did you do with the new HE400 drivers?

post #18 of 706

How is the sound of the newest HE-400s impacted by these 'small changes' compared to older HE-400s?

Never mind, dude.

Unfortunately, we don't know, either.

It's kind of the inside secret of HIFIMAN.

Sorry, guys. Still glad to hear from you.

Fair enough..

 

Will there be more driver revision changes / tweaks in the future or can we expect this to be the last revision for a long while? It's hard to review and talk about a product to those interested, when new versions of it with unknown changes are being pushed out.

Sorry, dude. The difference between the previous and latest is making you a little bit disappointed because it's not existing at all except the fact that the latest is more durable.

Besides, you could figure it out if you listen to them both much more carefully.

Hopefully, it could be a bit helpful for you.

Thanks.

Recently, no more changes of the driver. That means, it could last for a long time.

However, nothing is perfect. You can figure out the cons. yourself, and we so appreciate your voice or advice of improving our products.

That will be great and so nice of you. And we will make adjustments following your words.

Thanks a lot.

Actually I do have a good suggestion for the HE series headphones.

 

The current Hifiman headphones use the steel grills with honeycomb pattern, however it is not porous enough, so there is actually quite a bit of ringing and shrinkage of soundstage caused solely by the grills.

 

Myself and a few others have tried making grills from different mesh materials to maximize open airflow, to very significant sound quality improvements (expanded and more natural soundstage, and a smoother sound with less ringing).

 

You could refer to this thread I made about how I went about redoing the grills:

I have since removed and cleanup that sticky mess, which seems does not affect anything, but i do feel the mids suffered a little or it could be just me.

Please advise.

 

Hey buddy, sorry for hearing that bad news from you.

I could explain a little bit if you think it's true.

Firstly, you must have used that HE6 for a respectively long time. Since this, the driver you using must be a little bit hotter than before. However, it’s not because of the built quality of that headphone at all. It’s just because the headphone has been burned in for more hours than it should be.

Secondly, the foam inside the pads is more likely to be burnt out if the headphone is used for such a long time.

That’s why the foam inside became more and more sticky.

Nevertheless, you still cannot remove it or clean it up just because of its two functions which are as follows:

1.       Protect ears from too loud sound;

2.       Slightly alter the frequency response.

3.       Dust prevention

So, that’s also the reason why you felt the mids suffered a little.

However, you don’t have to worry too much.

We are here to help you out. We can ship a pair of brand-new earpads to you if your HE6 is still under warranty. Otherwise, you might have to pay a little for that replacement.

Sounds good?

Hello dear,

Sorry for that mistaken shipping of that ear cushions.

Eventually, we totally understand your situation. There must be something wrong with the rings located at the BACK/OUTSIDE of the driver.

No worries. Contact us at head.direct.customerservice@gmail.com one more time, please.

We gonna make another shipping of precisely what you need if everything is OK.

Sounds good?

Btw, I've got an old production HE-500. I haven't really abused it or used it too much but the paint on my Y-Yoke/Gimbals that are originally black have all but deteriorated. Now it looks a little retarded. What kind of paint do you all recommend me to use for a future repaint job whenever I find the time to do some touch up.

 

Or does head-direct sell replacement metal yoke's for the HE-500. I hear the newer models have a much better paint finish that doesn't just..  chip off with the wind.

 

We are so sorry for that bad news.

I am not quite understanding exactly where you need to paint for your headphone.

For convenience, could you take a pic. of that part?

If could, we can make a replacement for you soon since the only part--Y-yoke cannot be replaced separately.

Sorry for the inconvenience.

Hi there EricHD i have silly question. Why don't you guys sell ALL replacement parts for your headsets?? It seems other manufacturers of headsets sell every part on their sets separately  but you guys seem not to why is that??

Thanks.

So the lastest drivers are more durable right?? But the side effect of durablity is a drop off in bass quantity/impact and more sparkly/piercing higher end??

 

Ok why not from the beggining you guys just send out beta sets to your reviewers then iron out all the problems first before selling three different versions to the public? If you guys would have done so in the beggining you would not have three different versions that are soo vastly diffrent in sound signatures there would be only ONE!.

Wait there is no difference between older n newer drivers? Then,  "you could figure it out if you listen to them both much more carfully"

Thats contradictory no?

 

Even if he listens and hears the difference that does not tell him what you guys changed in the drivers but its understandable if thats an inside company secret cool.
