maybe I expressed myself badly or maybe the translation is not exact.
I wanted to say that with low gold the low frequencies take shape and, with the music I listen to, I like them better.
However, it is true that some details are lost. When you put any filter between the driver and the ear, some information is inevitably lost.
This applies to the low gold filter and all high filters (except blue).
I still did other tests with filters and now I'm more confused than before.
It is very annoying to remove the tires, unscrew the filters, reassemble other filters, refit the tires, which I do not even know how my name is in the end

At the moment I have changed my mind and prefer to use a low filter that is not gold and the high blue filter because it is a non filter. Then I prefer to play it on the grommets that I currently use in foam that guarantee a better result on my ears.
