ER4 sounds more precise, analytical and fast than ATH CK10 and UE TripleFi 10, It's truth?
Can't comment on the ER-4S or P version since I haven't heard them personally, but in my local forum's community among general audiophiles it's true that Etymotic Research have some of the best analytical, precision and speed when it comes to balanced armature in-ear monitors. Did auditioned the HF5 version recently which I heard from many were saying that it is a more balanced out version by Etymotic catered for a much easier, non-fatigued listening experience, in that they actually toned down the actual highs/sibilance issues originally found on the ER-4S/P, while introducing a slightly wee bit more of the lower frequency ala bass.
Someone actually gave a well-summarised review of both UE Triple Fi 10 and the HF5 before earlier this year while I was searching for reviews on, and I would probably agree with rangerid in his review in that in terms of treble details and quality they are much better than Triple Fi 10, which did not impressed me at all in terms of vocal details (but that's probably because I already own some of the best vocals/mid-range IEM on the market currently, which is the ATH-CK100) So it should be correct to say, for ER4 (both S and P version) they should be much more analytical in terms of treble clarity and quality, against Triple Fi 10 for sure since ER4 is considered to be much more analytical and refined in the highs, compared to the HF5/HF2 versions from what I understand.
Can't compare the ER4 to Audio-technica CK10 in my case here (since I never heard the ER4 like I mentioned earlier) but in terms of micro-details, treble clarity, speed performance the ATH-CK10 certainly gets my vote over Triple Fi 10.
It may be hard to believe, but JVC FX700 is the most analytical IEM I've heard because I can easily pick out all details with it. Everything is clearly separated and the dynamic range is vast which ensures that subtle details don't stand out more than they are supposed to and do not create a false sense of extra detail. ER4 is also very detailed, but it pushes more detail forward due to a more compressed dynamic range, making things easier to hear, but less natural sounding. With FX700 you can analyze not only detail but the dynamic range of the music as well.
Uh Pianist, no offends to you personally but cut it out already. You have been going to almost every thread on Head-fi to boast about the JVC FX700, even back in the DBA-02 thread when we were talking about bass properties regarding the DBA-02. Please look at the original threadstarter's post again, he stated that he wants a precise, fast and analytical reproduction of the sound signature, and we all know in terms of balanced armature drivers they would always be much more superior compared to dynamic transducers when it comes to both precision speed and analytical detailed presentation (at least according to what I have
read here and also from my personal listening experience all these years, which is why I have mainly stayed away from dynamic-based IEMs for my own collection, since I preferred that aggressiveness and analytical sound when it comes to my listening genres as well)
I don't deny in terms of dynamic range, dynamic-based in-ear monitors like JVC FX700 or Sony MDR-EX1000 can be much more superior than current balanced armature monitor phones (which is why I always turn to my headphones like RS1i or CD900ST/MDR-7506 instead for listening to orchestra and classical genres) but in terms of dub-step/rap/progressive trance/electronic music, I think no-one can deny here that balanced armature IEMs can accomplish with a much better performance than dynamic IEMs for sure (not referring to headphones though).
My 2 cents.
