post #3421 of 4783

My ER4S have returned today, we need not worry for their safety any longer. ;)


They also returned with a new friend, my latest add on for my source collection.

one problem here is volume matching. I play with little impedance adapters all the time, but it's really a problem to have so much difference in volume (going from nothing to 100ohm is no joke in level attenuation). so the ultimate dreambox would need something to compensate the different volumes for each impedances, but that part mustn't change impedance by itself... argh!

 

also depending on what IEM you plan to use in the futur, lower values can be nice. for an ER4 5ohm is a joke, and for W4 the dip in high mids is so huge that anything is welcome to reduce it, but some IEMs are super sensitive to impedance, yet really close to perfect(for me) signature wise. then just 2 or 3 ohm can be the icing on the cake to just make that 1db difference.

also I find it usefull when making 2 sources close in impedance output so that I can judge real differences.

 

anyway, if you make such a box, I want one! (unless you make your price tags like astell&kern)

 

 

edit: ahahah same ideas same critic, I love it!

 

Haha.  I'm thinking of making it.  I already have the parts list.  I'm guessing it would probably be somewhere between 40-50 dollars at most (12 resistors at $1/ea., wire, 2p6t rotary knob $6, 3x 3.5 jacks $5/ea., 2pdt switch $6, $3 heatshrink, case $?) for me to make myself not including a case.  Not sure when I'll get to it, but I'd like one for myself, as impedance changes a lot of iems.  I wouldn't be using it to "get the perfect sound" with the impedance, but rather to see the general effect impedance has on a certain iem.  Then I could always custom make an adapter with the specific impedance I find best for that iem.

 

The other option is to just make an impedance "box" without the switch, as I already have a switch anyway.  This would save half the cost almost, be more portable and be useable without the a/b switch to test anything.  That might be better for now anyway.  I could even throw in the capacitor to make a setting for turning the er4p into the er4b.

Hmm, just a thought at something that could potentially be much more useful for this scenario. Use a variable resistor! You might have to get crafty on making a knob, but then you have true fine grain control of impedance for the ultimate best sound.

 

EDIT: Actually, just get a couple with a philips head screw, and mount them to the case. Then make some taps so you can read the value with your DMM while listening.

I thought about that actually, but I figured something with settings would be easier to use, especially if I ever had someone else using it or made one for someone else...  Another idea would be a variable resistor with a readout, but then you're talking more parts, power needed, etc.

Well, I see where you're coming from there, but I do think a variable resistor would still be desired. For example, what if someone finds an IEM to sound pretty good with 100 ohms, but bright with 300 ohms. They are going to wonder about what lies between, because that's where the 'great' sound is! Besides, you can get a DMM for $5, and I would argue that anyone interested in this box surely knows how to operate one lol.

Not gonna lie. The ER4S and C5 is a pretty sweet combo. 

post #3427 of 4783


the ultimate impedance controller?  ^_^

channel imbalance free of charge.

 

edit: it's a poor joke, but I've realised that the sound was different from dap loud+remote low, to dap quiet and remote maxed out some 20 years ago on a sony k7 walkman. only now do I realise it was probably impedance at play with the old heostat stuff in the remote volume controller.

I've been saying that over and over.  ;)  It really is.

Isn't that funny?  I found that out when I first had my w4r.  I could hear the mid bass was a bit lower if the resistance of the volume adapter was higher.  There you go variable resistors!

So I am currently using the er4s with lineout via fiio x3 with soundmagicA10 amp and looking for a upgrade to my amp and would get a good fit with them and I end up cranking the volume all the way up.
I want a amp that's transportable like the jds O2 or portable. Requirements are smooth vocals, separation and details. Budget 300 and below? Try to suggest as many as possible. Fyi, rsa amps are too expensive around here, they cost around 600 over.

How about a JDS Labs C5?

Well, if it's in terms of sound quality maybe yes but from reviews I have read, they don't perform better than the o2 and the o2 is 80 dollars cheaper here just less portable.

O2 is a great bang for the buck, but just saying less portable doesn't really cut it. as long as you will put it on a table or in a bag it's perfect, but having it with your dap in a pocket on the walk needs some serious motivation.

 

well you know yourself and your habits/needs the best. we all are different with different lives, everytime I saw jude's rig my legs gave in ^_^.

Haha your absolutely right in your last part but hey I don't think it's really possible to stuff the O2 into your pockets while you take a walk without the volume going wild LOL. It's roughly the size of 2 iphones if I am not mistaken correct me there if I am wrong but also I don't listen while I walk because I find it less safe to do so. Can't hear people around you and stuff going on, I tend to sit down in a car or camp infront of my computer/s and listen to my music. I guess I should save for a RSA amp (600plus) if I can't get futher discount on the O2(209) then

I think everybody needs to be constantly reminded how everyone is different lol I always tend to forget that part and rely on reviews and chances are you ain't going to get what you want

ER4S loan has arrived.

Through the iPhone 5S:
Impressive sound. A bit different than I had expected over the years. Has its share of problems though that are very quickly apparent.

Wish I could run it through the 4S > Quickstep but it's on loan. I'll try the 4S and the D100 II and see what's up.

Most unexpected part:
Surprisingly heavy and dense images.
