I know right! I have wide bore Spiral Dots on both IEMs. I was saying to @Damz87 the other day that I hear Z1R and EXT's bass exactly opposite to how they graph. Bizarre.I don't know if that's true, personally. I hear a fairly even split between the sub- and mid-bass. If anything, there may be the slightest tilt towards the sub-bass to my ears. Crin's measurements show a bit more sub-bass on the EXT than the Z1R too, and it's the Z1R sample with the most sub-bass I'm comparing it against.
Do you have smaller-bore tips on the EXT, perhaps, which roll off the sub-bass?
Edit: most likely it's fit related. I get a fairly shallow fit with Z1R, which lends itself to more cavernous rumble, while a shallow fit is physically impossible with EXT.
