I stuff the donut (NOT Jada’s), but I don’t iem tips, just the foam bullets supplied by CC.



Mmmm … donuts.
I have them. How does it affect the sound?
Does @jonathan c stuff his holes? 🤭

What does stuffing the donut hole do to the sound?

I can't pinpoint it exactly. But trying the CC supplied foams, and various iem foam tips... the bore dimensions vary as the density of foam. Or the porousness? Not sure how to phrase it.

I ended up liking one paticular one for my taste (galaxy bud+ comply tip)

It alters mostly the bass and treble. I knew when the treble didn't "bite" as hard, and the bass basically didn't seem as "loose"

This would vary from person to person, and the changes are not drastic but noticeable just as with CC foams.

Yeah absolutely nothing wrong with the CC foam bullets. There are many IEM folk, so they have spare tips left over, it is just an extra option to fiddle with.

For ME, it makes the bass sound a tad more liquid, WITHOUT the (very) slight ‘veiling’ (for lack of a better word) of the original disc. There are four different densities, as you probably noticed, so you can experiment as see what you like best - and if you prefer nothing that is a perfectly acceptable conclusion, but do try. It is TOTALLY reversible. As I think I said in an earlier post, I use the most open foam bullet for the 600s because they need the most help in the bass, and the second most open in the 580’s and 650’s. I definitely do prefer the sound with the plugs, and my OCD is placated by the fact that the foam helps keep dust out of the otherwise exposed hole in the back of the driver.

As always, play around and decide what YOU like best with YOUR music in YOUR system. Not even Jada gets a vote - just you.

Enjoy!

YMMV, just my $.03, etc., ad nauseum.

I think that @jonathan c goes commando, on his Senns, but not certain. I do know that he removes the front foam as well, and replaces it with organza or gaberdine or bounty or something like that. I’m sure he’ll pop in eventually and clarify.

Right you are! All foam has been removed. I have the circular foams (spider web cage) kept aside in one piece. The earside foam has been replaced with fine mesh netting (bought at Michael’s, an arts & crafts store). You have seen this photograph, so here it is again:

…a ‘hole’ new meaning to ‘plug-n-play’…🙄
I won't comment on this one. 🤪 I had 6 posts deleted on the multiple HP's thread. Damn that Jada! 😂🤣😂🤣
