I once had the JH16, and the fit on that was awful. So in regards to custom stuff, there're more variables that affect the fit, one of them being the craftsmanship of the person making the tips/CIEM.
The problem I have with normal tips, is that the opening of the tips often get constricted, affecting the treble quality a lot. The length and width of the opening affects the peak frequency, I read somewhere. All I can say for sure is, the sound from the stock triflange is noticeably worse than from the custom tips.
I value comfort, so I prefer the custom tips. I could wear them for 4 to 5 hours without any problem. But with the stock triflange, 2 hours is the most before discomfort sets in.
I guess so. The only one that I will consider buying would be the K3003, but at 1300 the price is steep. I'd much rather pay save up that 1/3 to go for the SR-009. IMO, the TOTL cans are in another class altogether. There's a huge review here: http://www.head-fi.org/t/634201/battle-of-the-flagships-58-headphones-compared-update-audeze-lcd-2-revision-2-6-4-13
Also no offense, but it's rather impossible to get the exact same fit everytime. There's no way you can guarantee there's the same level of oil and humidity on the skin everytime. You could say it's very similar fit, but no way it can be exactly the same.
Edit: Like you I like vented drivers too. Those do sound a bit more natural. But I prefer to have it on headphones that I use at home. With IEM I just want isolation, comfort, and accuracy, in order of preference.
No offense again but why would you want to EQ the flat response (assuming you get proper fit) of the ER4S to something that's non flat, except perhaps personal preference? With proper source and amp, I don't find the ER4S anemic. Even though it's true that the bass doesn't linger too long but it's not anemic to me. One will always feel the bass from headphones better just because they move magnitudes amount more air than tiny drivers in earphones. That's what bypassing the outer ear does (pinna and ear canal).
In fact, I find the low end from the ER4S rather linear. The low end from the HD600 rolls off from 50Hz downwards. Have you heard of planar dynamic/orthodynamic headphones? Bass from those headphones are what I call proper bass. If you like linear bass down infrasonic range, I think you might like it.
first, i was talking about custom tips for my er4s, not custom iems. Second, it does seem like a bad mold, but i've been molded twice with and without a bite block. Both are sub par. Perhaps it's my audiologist, but i'm guessing it is microsonics. As you said, the craftsmanship matters.
As for not getting a perfect fit every time, i disagree. I can fit the pfe112/232, er4s foam/triple flange, sony xba3, westone 4r, shure 535, etc. identically every time. I get consistent sound and comfort. All of the time. I could do this as well with the f111, but i would achieve the non-perfect response that is warmer and less accurate. The graphs i've seen show er4 like response. To achieve the desired response the fit is very inconsistent. The question is which response were they designed for? If the warmer sound, then they are consistent. Either way, for accuracy the perfect fit is required. In that case they are inconsistent. If they were designed so that accurate response could be achieved the same way all those other earphones achieve their target response with normal insertion, then i'd be happy. But perhaps they wanted it warmer, I'm not sure.
Regarding bass, my preference isn't the issue. The eq i discuss is to make the bass flat technically. It is not flat stock. Very close, but not flat. I never described it as anemic personally. It's not. But it rolls off in the sub bass region starting around 50hz or so. This isn't my preference though. I based this eq off of frequency response graphs from multiple sources, my ears, and the ears of other experienced audiophiles looking fir flat reference sound. Even with a perfect fit this is the case. I am aware that different types of phones portray bass differently, and i'm not compensating for that, but simply aiming for perfectly flat response in general.
Regarding an amp, sure with the "right" amp you could get more bass and need no eq. However, that amp wouldn't be flat if you're talking technically. Nothing wrong with that. But i want my gear to be reference in every way possible including frequency response. I can always adjust eq to tailor to my preferences, although my preference is pretty flat to begin with if the phones are good.
The hd600 also suffers from sub bass rolloff as well as mid bass boost despite what sone people say. I eq the mid bass down a tad and sub bass up. It really opens the sound up, although they still sound great stock.
I haven't heard those other headphone types. Perhaps sone day. Personally i don't really have an issue with iem bass if it's flat. I can't listen to bass boosted earphones anymore even. :-P
