Today I was tip-rolling and I've found out the ZS10 Pro and JVC Spiral Dots to be a bit shouty and like some people say "steely" compared to smaller bore tips, it's like high-peaks get a bit uncontrolled.
However, I do really enjoy the increase in wideness aspect that JVC tips help to bring. For my luck, while reading the forum I spotted the james444's signature which has some cool mods and I came across with his
DUNU 2000J Blu-Tack mod.
It's interesting, the design choice from DUNU for this model is similar to KZ in putting a BA in the nozzle which I do believe is the main reason to create an artificial-ish timbre at higher volumes since they can get a bit shouty without proper damping. This mod seems to fix this extra "steely" tonality to me and it is rather easy to do. Btw, james444 isn't joking when he says to pinch off the
smallest piece of Blu-Tack, my smallest piece of Blu-tack ended up being way too much.
My goal was to make the nozzle grill looks like a watch, with a mini-screwdriver it helps a lot to adjust it to the center.
I can say IMO the timbre gets more organic, the peaks get better controlled so I perceive it as more correct sound, really enjoying it! Also, if you don't like the result, it's even easier to undo it.
