True, The ER4S is what a lot Closed back headphones wish they were. The soundstage on them still wider/3D than what a lot reviews let on?.

Also probably the most flat (in front of you image) that you can get at that price. Even my LCD-2 doesn't quite project quite the same sort of image (it's more of a through your head presentation).

I think so personally. It’s still not the biggest stage obviously and it’s not like wearing a full sized set but it’s more open sounding than I expected from reviews I read. However, I feel you need a good source to get them to open up. They sound more congested out of my phone but wider and more precise through my portable amp.

The openness is caused by the boost in the high treble starting at 10K. A region that is elevated about 2-3 dB compared to the reference Etymotic target. I'm guessing they chose to boost the high treble to compensate for the missing 6-8K (about 4 dB below the Etymotic target).

It highly depends on the music used too, Which I've noticed. So it not forcing it on everything like other closed backs or IEM's do. Which makes sense since its mainly a Studio focused IEM, Some ER4S reviews can get almost hyperbolic with it being "2D the headphone". The imaging is the ER4's strongest point in my view.

 

[FastAndClean]

the only negative i can think of about the performance is the soundstage size and dynamic range, that is about it, the speed, neutrality, imaging despite the smaller stage are great
also the ER4S have one of the sweetest sounding treble for me

They look a lot like the one's I have on my aftermarket cable

For reference, here are the stock connectors compared with the aftermarkets. Huge difference.
FWIW - been using the stock cable, and they are much more comfortable now ... I feel the discomfort I'm associating with these, is not inside the ear, but at the entry point. The smaller connector means less contact with the ear. Still very aware of these, but feel like I can wear them longer now.

I wanted to leave this graph here in case it sparks anyones interest.

Yes the EJ07 is what Etymotic would be if you made it ultra fun and bombastic.

 

[DeliriumCordia]

Is anyone aware of an aftermarket cable that uses the same physical connector as stock, and is about 4ft? The 5ft cable is just awkward.

As someone who can just about use the stock er4 cable as a jump rope, I'd also like to know this.

I think part of this has to do with bass roll off. This isn't a big deal for me because each distinct sound is so precise and clear that I can hear every detail.
If you don't mind my asking, which source do you use? I've been interested in experimenting with different sources for a while (like the iBasso dx200/220) to see what all the hype is about.

Fiio Q1 Mk II. Nice little portable unit.

Have been using ER4XR / ER2XR with Fiio Q5 / AM3B combo, it sounds wonderful.

i found ER4P second hand for 64$ but i have already ER4S, do you guys think it is a good idea to buy them to have a spare?
the price is very low

Absolutely.
At this price it is a steal, i really like the P series alone, and you only need an adapter to turn it into an S. I’d go for it in a heartbeat.

edit: just realized I’m 2 pages late, but whatever.

Was shocked to see the price on these.
When you say it opens up the sound, are you referring to the upper treble?

 

[Blackwoof]

Wait wouldn't the resistor help the ER3SE's treble to?, Since going by Crin's charts it's the same as the ER4PT's.
