That's the graph that show the treble bump around 16k on the er-4s and 4b something I wouldn't call neutral.

Just use Klipsch oval tips and that bump is gone. Nothing is perfectly neutral, that has to be accepted as well.

I agree with that, etymotic make hearing aids and they designed them that way I haven't heard them so I cant really comment on how they sound.

Couple of observations (again, I use my ears more than anything else and compare them to neutral speakers, of which I have constructed many). I feel measurements to need to be corroborated by subjective observations by trained ears to be useful.
 

• Most people are not going to hear 16kHz. 14kHz maybe. A bump at 16kHz probably isn't a harmful and will add "air" to most people who are older than 20.
• IMO, IEM measurements have some issues with resonances inside the couplers in combination with the tube lengths of the IEMs. This is why we typically see two spikes in the treble measurements. I don't necessarily hear these spikes. Personally I don't think any coupling device is accurate above 8-9kHz. Keep in the mind the speaker measurements for neutrality do not consider these resonances and only take the measurement via a mic in free ear. In other words, the human brain / ear mechanism takes the canal resonances and filters them out.
• To me, the ER-4S sounds on slightly forward side of neutral (a bump in the vocal harmonics region) with some treble energy around 8-9kHz. The bass is acceptable with deep insertion. Still, I prefer to run it with EQ to give it some deeper bass boost and cut the treble a tad to avoid fatigue for length listening sessions.

Also, I hate threads like this because I read the first glowing post about the product and then as I continue to read the entire thread, the enthusiasm seems to die down and instead turns into a desire to try something else or "the next step up"
 
I was considering these over 1964ears V6 or AS-2, but now I'm not so sure.

My enthusiasm for the C4 has NOT died down at all. It is still the best IEM I have EVER heard.

You need to dig deeper or buy and try all.

Not sure where you see the enthusiasm dying down or if you've gone through the whole thread in-depth, but I've only seen two other posters that have already received their C4s, both of which gave favorable impressions to the C4s.
 
It's still a really new IEM, people who placed their orders shortly after Luis' review still haven't received them (or at least I haven't

).

Hey LFF, is that solid black color pictured in your first post not available to general customers? I don't see it in the customization options...

 

[engelhaft]

has anyone heard the C5? I wonder how would it sound compared with the jh16 or the merlin

as i know , they can do most of color outside the color chart but it will cost $60

Instead of the usual peak at 9kHz they have a very steep hi cut filter...

Under important must read notes:
 
"The IEM measurements coming up may be subject to change. I'm still working on a few things to refine the process. There is one important thing that folks should note: the FR graphs will not extend past 9kHz because that's the point where I feel the measurements will be misleading. The IEM measurement couplers tend to produce their own resonances and peaks between 9-14kHz. Such nonsensical information will not be posted because it only causes more harm than good. Heck, even the documentation on some of the commercial couplers state they are not accurate past a certain point."

 

[tumburu]

Oh, I  got it, it's done on purpose. It should be better not to display the steep cut off and just stop with the line at 9k to avoid confusion.

Thanks for the clarification. However, on full sized headphones the measurements contain information above 9k and that caused the confusion.

I will be a first time CIEM buyer, and the reason I am looking into it is because I seem to have a finnicky head. Clamping preasure, headband padding, and pad depth all affect me too much - but with a CIEM I would have none of the issues.
 
As a first time CIEM hopeful - what can  expect from these out of different devices? (ie: An ipod touch, a laptop, etc)
