I am thinking maybe removing the foam ring + adding some foam like that beyerdynamic thing would maybe smooth them out a bit... Anyone tried that?

 

Yeah removing it is a good idea. That ring is just a hack by Hifiman to distance your ears from the driver. But adding anything may just muffle the sound

Thats why I get bothered with my mobile setup for the HE-400. Granted the Cowon i9 has some EQ options that are very nice, but even if i know how to set the settings to lower the siblance, I dont know how to set the rest of the eq to make it sound nice (most of the time I use Crystal Clear option).

I had made a chart a while ago when I was trying to figure out what sort of power I needed to ensure playback levels of about 110 dB or more.

 

The rule of thumb says that, each time you double the amount of power to a speaker, you increase its playback by 3 dB.

 

Using that rule of thumb, the HE-400 needs about a half a watt (0.5 watts) to produce SPL reaching 120 dB - which is as loud as a gunshot and a little beyond concert levels. This is based on claimed efficiency of 92.5 db @ 1 mW. This is about what the O2 can do at max power, so that is one reason I chose that amp.

 

If anyone was foolish enough to purchase an amp that can do 4-8 watts (!) for the HE-400, theoretically they could be pushing the phones into the 130 dB range, which is just stupid. All that extra power, btw, is 'purchasing' about 9-12 dB of additional headroom.

 

If you have an amp that can do 200-500 mWs for the HE-400, you should be more or less able to push into rather extreme loudness. The only reason to go for even more power, IMHO is if you listen to a lot of movies, or classical or other recordings with high dynamic range (HDR). In those cases, the extra power is probably a good idea to ensure you can reach listening levels that are a little beyond 'good nuff'. Given that the power requirements start to get very high very fast after the 1 watt level, however, one has to be aware that the amps producing in excess of that amount are going to be very pricey!

 

This is also why buying tons of power for regular speakers (usually rated at 1 watt/X SPL), can be a real waste of money. The difference in loudness between a 50 watt amp and a 200 watt amp is really only about 6 dB (3 dB jump 50-100, 3 dB jump 100-200 watts).

 

I was going to engage with the "Tizzy" and "sibilance" topics again, but they are getting to be a dead horse! Suffice to say, there seems to be an agreement that the problems are 1) recording dependent and 2) 'fixed' in part by reducing treble in the 8-10 khz and 16 khz range. I also recommend a small cut in the 1 khz region (between 500 khz-1.2 khz). It is appropriate to distinguish between vocal sibilance and instrumental, since they are not the same thing. My instinct is that some people are confusing the two and forgetting that sibilance is not by definition a bad thing - otherwise why would we ever record cymbals for example?

I think siblance is not by definition a bad thing, but can get tiring really fast.

Im guessing you dont have to totally get rid of it, but lowering it a little seems like a good idea to me. Also i guess this is where personal prefernce comes in :D.

 

Ill try your recomendations on the Eq. part!

About all the spl stuff and amp requirenments, I think you can't just put it in to boxes based on numbers, but for planars, I think it is a good starting point, that they need enough power to reach 120dB. In the case of the HE-400, that eqauls appproximately 560mW. For the HE-500 it would be 1,5 watts.

Hmm now you say the velours are better for smooth treble? I read before that the pleathers were the best for smooth treble?

 

Which give the smoothest, least sibilant result in the mids and treble? Pleather or Velour? I can EQ as well but I am not sure if I should buy a pair of velours to replace the stock pads?

 

I want the smoothest possible sound from the HE-400 in the mids and treble, while keeping the bass and lower mids as good as possible.

Velour seems more open, but still with less glare. They do have more treble. The best you could do, is to get one of modulors jergpads.

 

The pleathers are the smoothest sounding.

I don't see how it can have more glare but be smoother sounding?

 

Are the jergpads the best for smooth treble?

IMO, yes.

Just get the jergpads made by Modular and save yourself the time puzzling it all out with the 400's.

They are velour over pleather and they have been modded to take the edge off the problems with 400's.

Yeh I did ask but apparently they are only making 15 at the moment and there are already 15 people who want them, I was looking for any other quick mods which might make them better, maybe I should just have a go at the jerg pads myself. Although I do not really want to mess it up and destroy a pair of pads, I expect jerg and modulor have better skills than me and know what they are doing.

If you are fairly handy, it's a fun little modding project.

 

The good thing about my mod is that it is in 4 discrete parts, so at any one step you could test the earpads out and evaluate for yourself if a step sounds good / if you want to bother doing more.

It doesn't look THAT hard actually, just the velour bit looks a bit tricky... In this current heat I do NOT like wearing pleather. If you just remove the foam bits and then cut the holes in the pads... What effect does that have?

 

My main concerns are reducing harshness / sibilance / glare... Although increasing the sub bass looks good as well. I would like some that have been made by someone who knows what they are doing though, because I don't actually understand what the point of cutting holes in the pads is...

 

I have not even got the HE-400 yet, should get them tomorrow, I really want to like them, even if that involves modding them, because my amount of headphone purchases and returns recently is getting out of hand lol.

 

Another question, how big is the difference between the rev 1 and rev 2 ones? The ones I have ordered have the white / slightly transparent grilles... Here is an image...

The damping holes? They are to help damping in the midrange. It's a significant boost to midrange clarity, and brings out the upper midrange to be more in-line with the treble (perfectly well with HE500, very well with HE400).

 

If there is any step that's mandatory in the mod, it's that.

The Rev 1 is almost impossible to find due to being sold out on pre-order and also having been recalled due to a high failure rate.  If the plastic around the driver is white, you're alright.  If it's black, take it back!

 

Also, I am one of the people who ordered the jerpads from modulor and I am getting an LCD2 in soon (hopefully tomorrow).  I am only keeping either the HE-400 or the LCD2 so there may(!) be a nice pair of jergpads up for sale from his first batch soon.

I found the LCD2 to be better in every single way to the 400's....except price, and so I have the 400's. smily_headphones1.gif
