Thanks. I'm going to take this foams discussion just a bit further.Ok. I'll take one for the team and get a Qigom diy on my next purchase.
And thanks for the detailed explanation. It's good to know that I picked some quality donuts right off the bat! I was using my Vido's last night(I forgot how good these sound) and was thinking these would be perfect with a little more bass. So that's cool that foams are like tips for iem's. So i guess that would be called foam rolling?
Anyways thanks again for the info. You're appreciated
@samandhi mentions how foams actually filter out the high frequencies which in effect appears to increase the bass. It's a very good post.

I followed up on his post with my thoughts about using foams from the same source and batches for consistent density.

And finally, I had made foam density measurements which show that certain brands of foams have better quality control than cheap no name foams.

Ok, I admit this may be over the top, but it never hurts to have more information than not.
