PM Me your addy and what colors you would like to test. When I place my order for my ER-4s, I'll add what you want. Then send them to you, all at no expense.

Will do.

Just to be technically accurate, none of these filters actually increases bass levels.  They only FILTER (reduce) the treble response, and midrange and volume some, probably, so that when you turn up the volume to compensate, you are hearing more of the bass region.

 

I would argue that limiting or reducing the treble of most Ety phones also limits / reduces the level of details which the Ety phones are famous for; and I would argue that the only way to increase the actual level of the bass is to use some type of EQ which can raise bass response without sacrificing treble or midrange response.  That is the method I would choose to increase bass response to my ER4.

This has been said numerous times in the thread.  I have also played with EQs to confirm what you stated as well regarding limiting the details.  The reds seem to be the best balance (through EQ testing) which still keeps most details there, but really doesn't sacrifice much.  If you go past that, you don't have Etys any longer XD

Increasing resistance from the stock damper does increase bass a little, but most of the change happens in the treble. For the BAs at least, I don't know how the dynamic MC5/3/2 responds, it may be different, that's something to consider. 

 

Choosing a damper depends on the model

 

ER4B as mentioned by Rin, is most balanced with orange filter, but sounds pretty good with red and even yellow as well. 

 

HF5s, personally these sound better with less acoustic resistance as they are lacking a bit on the treble. Currently using brown filers with short tips and the balance is impeccable,  it increased treble enough to balance the sound while maintaining it's bass. I wouldn't use a lower resistance than red for these, same applies for the ER4P. 

 

ER4S, nice with brown and white, red for a warmer sound, will not use with any other ones.

I just received my order and briefly tried a couple different ones with my very old Ety ER-4S's.

 

First I tried the orange: To be honest, I couldn't really tell that much difference from the stock green. Yes, the highs may be a little lower and therefore I turned up the gain which gave me more relative bass. To me it was pretty subtle. But overall it does work to give more bass and I could barely tell that there was any sacrifice in the highs.

 

Then I tried the yellow: Now I had to turn the gain up more and of course quite a bit more bass, but at the expense of losing some of the high's that we all love about the ER-4S's. Still, even though there may be a little less detail, the relative increase in bass is quite welcome. I think I could actually live with the yellows just to get the bass, but I am sure many people would not be willing to sacrifice the highs at all. To me it might be worth the trade-off.

 

I have not tried the others even though I have them. But I figured if orange was subtle, then going down to red doesn't seem like I would be able to tell the difference.

 

For now I am going to stick with yellow and see how I like it longer term. I know that may be sacrilegious for ER-4's...

 

On another note, Mouser made a mistake on my order. I ordered two of each filter. They sent me two of each except, for some reason, they sent me 2 boxes of yellows! I guess someone read it as 2 of the 100 piece boxes instead of just two.

 

For the cost of the filters even with the shipping, I can't imagine they are making any money since it appears as if someone has to go to each box, pull out two, put them into bags, then put them into another bag print all the labels for each part number, and then mail them out.

 

So if anyone wants to try some yellow filters, I have more than I can use. I could just drop a pair in an envelope and mail them out. PM me if you're interested.

 

Or I suppose I could send them back to Mouser...wink.gif

Brown and white for ER4S? Wouldn't that give you even more highs? I think the ER4S's have plenty of high end with the stock green.

I would call and send them back.
Thanks though, Jim

is this real or exaggerated? I don't want bass monsters but sometimes when listening to bass heavy music I would like it to extend and maybe go a little deeper.

It is a very real mod that improves the bass.

 

I might have gotten a lil excited by the improvement though.

 

But, It will bring out a more satisfying bass in any IEM using these filters.

 

IMHO, Jim

I'll give more insight when I get it.  Based on my EQs that I used (earlier in the the thread), depending on the filter used, you can get quite a bass boost.  You can get better bass presence (won't create depth from thin air though) which leads to a better perceived depth though.

Judging by the EQ I used, it will not.  The depth of bass presence is improved at least 2-fold here, but the bass becomes more solid and veiling, not textured like it should be.  I'll judge the actual filters when I get them, but based on the EQ, I'm expecting some veil from that  There are plenty of bass monsters out there that don't veil (the 3.Ai for example have little to no veil).  The EQs showed a lot of compramises (which I was expecting based on the graphs I saw).  Just as an EQ can only do so much with compromise, same goes with a filter.  So you'll get gains here, but losses there.  With bass, the same story is expected.  

 

Remember, the Etymotic house sound tends to have a slight (1-2 dB) mid-bass hump to create faster, punchier bass.  However, if you increase presence in the bass as a whole, this midbass hump begins to sound bigger in general, this is the area that creates veil (like in the Westone W4).

This was a mistake from my end, meant orange and red for the ER4S.  Red seems to be a good sweetspot, makes it a bit warmer while retaining most of the treble. Brown wouldn't be a bad idea though, but it will make it very revealing like the ER4B, which means harshness when listened to most modern recorded stuff.

Tried white ones on my HF5's, liked it, though curious about the brown ones now. I currently have the white filters in my SM3 v2's, and although they sound great(more neutral and detailed, how I imagine W4's to sound), I might try brown on them too. I'll be making an order of all the filters on Friday ^_^
