tenore beats ue600
too much low treble dip on the ue600. the titan is different in that it sounds more "real" and "3d" than the tenore, but I'd argue a tenore with good bass level is more accurate than both.
What about layering and micro details, imaging, notes depth and finishing.
Tenore, tenore, tenore, tenore and tenore.
Haha. But really, the bass on a tenore varies by set up to at least 6db sometimes from tests we've compared here on the forum. If you get a bassier tenore, the ue600 might be more revealing and accurate overall. With a neutral bass tenore, the frequency response is nearly identical to a red filtered er4s with better sub bass. I'm talking 98% identical.
I don't know anyone, anywhere that would say the ue600 is more revealing (or any of those things) than the er4s. And therefore, the neutral tenore. But it would be easy to hear otherwise if the tenore was bass heavy. So sad that they have that issue. Otherwise, I'd probably still consider it the most accurate earphone to date.
The tenore isn't necessarily the most amazing with "imaging". However, earphones are a tricky thing. To replicate the "3d-ness" of a speaker, I personally find an earphone with additional treble in the right areas, or even a slight cut in lower treble in certain areas (similar to the re400 for instance, although overdone) can give a more 3 dimensional quality to things. The titan 1 sounds more 3d and spacious than the er4s or tenore, but I wouldn't say it is as "accurate". If you want to hear "every" detail found in "every" region of the frequency response, the tenore and er4s would be better (assuming no EQ).
However, some people like to hear what they call "micro details", but it's really more like treble "sharpness" in the right areas. And while this might sound awesome, it can also mask the smoothness and details in the mids. Something like the er4s or tenore might sound dull in comparison, but when you really listen to something complex, you can hear every naunce, everywhere in the song. No "one" thing stands out as amazing, but the whole "mix" of the song sounds great and every little "micro detail" can be heard when you listen for it.
But the truth is that NONE of these are truly accurate. Even the er4s and tenore can use EQ to improve their bass and treble. But alas, we are at the whim of the earphone manufactures :-/ I'd give anything to be on the production and design team of an outstanding earphone.
I would make the flattest most "accurate" iem possible using all researched targets and monitors as a guide and then design the earphone to have a few filters to compensate for common ear issues like resonance and whatnot that differ between users. Obviously this wouldn't be easy, but gosh darnit, I'd make it happen!!!!
