1. @luisdent, thanks for the comparison between KC06 and Tenore. Based on your observation I'm once again questioning whether I have reference Tenores or bass-heavy ones, as I find the KC06 to have the more airy mids not the other way around. Also between the two I find Tenore's darker. We're in full agreement on the fit and isolation and bass.
2. @Pastapipo, I hear "ts-ts-ts-ts" for KC06 and Tenore. So more natural sounding, not smooth..
3. Magnets! About 100 pages back, someone posted a picture of Tenores stuck together because of the strong magnet. I tried this a few times and at most I get them to 'kiss' when hanging them side by side. They won't stick together though. Does that mean I don't have reference pair?
To me the tenore hi-hats and whatnot sound very real, but relatively speaking, the tenore sounds like Ssss-Ssss-Ssss, while the kc06 sounds like Tsss-Tsss-Tsss. There is a slightly more metallic-ness to anything metal. Acoustic guitar strings, percussions, chimes, etc. They (kc06) sound more believably metallic to me by a slight margin. Compared to other iems, they both sound a lot more metallic and realistic when called upon to represent that sound.
As for the bass, with the correct fit on both, my tenore and my kc06 are almost the same overall flat response. The tenore has a touch more sub bass while the kc06 has a touch more regular bass. However, the tenore is almost a ruler up to the top end, without a teeny bump around 2-3khz like the er4s (but less) and a slight dip around the 4khz region here or there. Both very slight.
While the kc06 treble sounds better to my ears where it is prominent, as thought it is very very smooth in that area, but it does sound a hair about neutral. And the extension doesn't disappear, but it starts a downward slope in the very high treble where the tenore just keeps going. This slope along with the slight increase in regular bass, plus the general "v" tilt gives them a darker (for lack of better words) tone than my tenore. However the tenore has more low low end, but the linearity and extension give it the lightness comparatively speaking.
Here is a very very quick drawing I made to illustrate how I hear them. These are generalized graphs, they aren't meant to represent any specific frequencies, but just how I hear the overall differences in regions. The differences are pretty small considering most earphones sound drastically worse ;) hehe And the graphs don't represent scale or anything either. Just a general idea.
Also, the kc06 is a lot louder at the same volume than the tenore...
