Great album trough great IEMs - no wonder you got emotional. Thanks for sharing !
Agreed. Every now and then, ads turn honest/true. This one nailed it; despite - or precisely because of - being written in "Chinese poetry" way.
These iems are already very clear sounding iems. Because of curiosity I have just removed the metal grille of B3's.
They sounded even clearer after this. Highs didn't got harsh in my case. Only clearer but not sibilant.
But, for my ears they sound more natural while the filters were on their place (not 100% sure).
Sound spectrum or characteristics didn't change in general (as far as I can sense or perceive). Its clearer now. May be bass got some more impact too. Not sure... I have to A-B...
Anyone who wants to get more clearer highs can try this. But for me its not needed. I will be putting them back (after cleaning).
I wouldn't directly advise doing this to somebody though... I have also seen very tiny bit of earwax accumulated behind these metal grilles (which I was worried about).
After shooting the grilles back side with my macro lens I was surprised (disappointed)! Front side of the grille seemed clean by the naked eye but the back side were covered with a mixture of ear canal dirt (I think theses are wax, dirt and dried sweat).
Even though I am a clean person -who takes shower everyday and cleans his ear-canal with 2 separate q-tips after each shower- I couldn't believe what I saw
I am sorry to share this wax and debris. But I believe we need to learn... I couldn't be able to see the grille in this detail. Thanks to my 105mm macro lens its giant now and I can understand whats on (or in between) the grilles...
After cleaning the grille's putting them back in their place will be tricky, because I have removed the 'double sided tape kind of adhesive' which holds them in place...
FYI.

Havi B3 Pro (metal grille removed)

Havi B3 Pro metal grille from the front: You may not be able to see any dirt when these filters are in their place.
On this photo you may see something underneath them...
But the black background (when these are on their place) eliminates the detailed vision of the grilles.

Once you remove the grille and turn its back you will see the reality (you have to magnify or take a macro shot)
