Yes, I am aware of your mod (especially for the A6). Although, I am pretty sure you used some DIY materials you made yourself, rather than the ones you can just buy and use at once.

These:

I have used those from that link. I told the seller to make a 50/50 of low and high density since he mentioned their difference and he agreed. Quite nice not to be worrying about foam size and proportion with that. It really adds new ways to tweak and play with filters.
Currently I'm putting 3 pieces of low density on LZ A7 Black and 1 high and 1 low on LZ A6 Black.

About the foams, I have been trying those foam filters with my LZ A7 and LZ A6. The first thing that I did after trying many days with my LZ A7 was to peel off the small filter inside the black nozzle and put foam. There is a difference in density between those two; the black one is way denser than the white one. I feel that the foam/sponge material works way better as a filter for high-mid and treble peaks than other materials.

Here is the comment that I have made months ago.

Did you also remove the original filter or only put the foams?

At the start I only removed the cloth piece from the back, recently I also removed the metal filter on the top, trying to mimick what Sony does with their foam filters on their high end IEMs. I actually really like the result with both filters peeled and adding foam afterwards by yourself.

I guess I will try on blue nozzle first with low density foam as this is what I have now.

Thanks

Interesting, do you mean that he can make a custom order where half of the foam piece is low/high density, making it a hybrid density foam?

You stacking them? And I was a bit worried about removing the cloth mesh since that blocks the foam from falling into the iem itself and because the cloth mesh is probably a dampener, so removing that one should have an effect on the sound.

I only asked the seller to sell me half high density half low density since he mentioned the difference, nothing about hybrid densities. At that time the description was only "black" and "white", nothing about density.
Actually, the piece of cloth is the one that affects the most to the tonality, that was the first one I removed to put foam. Later on I also removed the metalic one to mimick Sony's approach.
Yeah, I have been stacking them trying with different combinations and ended up with that. The foam don't fall into the IEM, they are so light that they get stuck on the walls of the nozzle, so you will actually need a needle to grab them out.

Yep, its a dampener.

The Sony recipe indeed. This is how I do it on a lot of iems. Works like magic.

The mod of the blue nozzle with three pieces of the foam reduces the treble harsh which is expected. On some songs it still sounds too harsh for my ears, perhaps I should try with high density form.
I place back the metal gril to cover the foams by the way.

Comparing to DQ6 which is also modded with 3 pieces of low density foams, they sounds quite different to me, LZ A7 is more V profile while DQ vocal too forward.

I only use 1 piece, the high density foams on both of them though. Feels quite risky to insert that many foam in them. (especially the DQ6, since that one is going right into the body.)

I am aware and still taking the risk as one or two low density foams still not enough to tame the high freq LOL.

Yeah, low density dont have much effect, at least when i just tried one. Have you tried only 1 high density piece?

 

[Luis1316]

I also have to mention that I use a easily chopped foam tip instead of your ordinary silicon or whole foam tip, so my perception might not work for your preffered tip.

 

[sutosuto]

Have you tried only 1 high density piece?

I do not have the high density foam yet

 

[RikudouGoku]

They are a lot better IMO.

Low density dont do much, at least when you have 1 piece.
