etymotic er-4 aftermarket low-microphonics cable?

post #1 of 27
Thread Starter 

hey guys, i love my er4's sound and isolation, but im getting kind of irritated by how much noise the cable picks up... wearing them over the ears are beginning to hurt and it only helps somewhat

 

recently i have discovered that the drivers can be detached from the cable, so i was wondering if anyone makes cables which can replace the one which comes with the er-r earphones

it would also have to include the resistor that is built into the stock etymotic cable which defines if the er-4 is a P , an S or a B

AW Audio Accessory in Hong Kong sells Westone cable adapters.  They are available in P, S and B versions.

Just out of curiosity, how old are your ER-4's? I only ask because I bought a pair of ER-4P's a few years ago and my original pair's cable was extraordinarily microphonic. However, I had to return them to Etymotic because one of the drivers stopped working. The second pair they sent me had a cable that was not microphonic to my ears at all. Very odd.

The new ER-4 cables are less microphonic but still really bad, I'd recommend using the shirt clip if you don't already.

 

That Westone adapter looks awesome, I build cables for those and now I'm glad to have an option for fellow Ety lovers! Super awesome!

well guys i've completely forgotten about this thread since i started listening to my er-4p's with my shirt off, since thats where most of the microphonics come from

but then one pair of my er-4p's started have the left side cutting out, it seems that the cable is giving at the flexible base which attaches to the driver units .... the skin of the wiring is torn and i could see bare copper

 

so yeah , not only are the cables badly microphonic, they also dont last that long... best start looking for a Westone ES cable now....

Do those Ety S version adapters have the 75 ohm resistors built in so they will transform my current ER4P into ER4S?

 

Which cable form the same suppliers will work with the adapters?

You can use those 75 ohm resister adapters with any IEM cable, ER4 included. A lot of people already do. The S adapters do indeed turn them in ER4S

I was asking if these adapters have the 75ohm resistors built in

No they do not, I've verified this, the resistor needs to either be added onto your ES cable (easy to do if you reterminate it, the resistor can be concealed within the plug) or you can use the S adapter.

 

If you can stretch for it, Apuresound makes a beautiful replacement cable that provides sonic benefits for what I believe to be a modest price considering they kind of have the monopoly on stock-pinned Ety cables.

Then I do not understand why they sell an S a P and a B version?

DOH!

 

*Epic facepalm*

 

Disregard everything I said. That would explain some things...

Oh man, I just wrote up a complete tutorial for doing this mod, and the editor blew up and lost it all ... :angry_face:

Here we go again.

 

I recently bought some ER•4PTs, loving the sound, but hating the "microphonics" (technically, it's "cable noise" as microphonics is something entirely different, but anyways ...). I used the info in this thread to buy and install awwan's AW Audio ER•4 adapters for Shure cables and am now in Etymotic Nirvana.

 

awwan has adapters for 4S, 4P and 4B models, with the necessary resistors (and capacitors for 4B) inside the adapter casing. If you have the 4S, you can convert it to a 4P by using the "P" adapter and then go back to 4S at any time using the P-to-S adapter (basically a 75 Ω resistor in series), which awwan also sells for much less than the OEM unit.

 

This is the 4P adapter - Shure cable version that I bought from awwan.

http://www.ebay.com/itm/290630811020

 

Note: This mod likely voids your warranty, but you can easily revert back to the stock cable should you ever need to send your ER•4 back to Etymotic for servicing.

 

On with the tutorial!

 

While waiting for the adapters and cable to arrive, I used this stopgap method (found here) to wear them more easily over-ear. The stock cables were still really noisy. Don't think you can find a noiser cable, braided or not.

 

I used a pair of side cutters to start prying the stock cable connectors off of the armature enclosure. Work slowly from all directions to avoid bending the pins.

 

When the cutters start touch the pins, find something thin to stick between the pins to continue prying the connector off, like a very small screwdriver or a nail (I used an old dental hygenist's scaling tool I got from my dentist a long time ago - can't remember what I wanted it for). Work slowly to pull the connector straight out so as not to bend the pins.

 

When it's off, it looks like this. The fatter pointy pin goes into the larger hole with the visible copper lining.

 

This is the orientation of the AW Audio adapter compared to the stock connector. I started with the left earpiece, so you can see a blue "P" indicating the left side and 4P version.

 

Now insert the adapter with the orientation shown (fatter pointy pin goes into the larger hole with the visible copper lining). Carefully press the adapter pins into the armature enclosure, being careful not to bend the pins. I was able to do it with just finger pressure.

 

And voilà! We're ready to connect the Shure cable. The adapter with the red "P" label is for the right earpiece.

 

And the finished product. I used the Shure CBL-M-K cable with 1-button remote for convenience with my Samsung Note 3 and Galaxy S3.

 

How they look worn over-ear. The Shure cables with remote have a bend that their other cables don't. This doesn't seem to be a problem as you can insert the ER•4s at whatever orientation works for you, either for over-ear or straight down.

 

Happy "microphonics free" listening!

I find this mod very interesting.
post #14 of 27
I use small dog hair bands (real small rubber bands) and loop it in a similar bundle. It helps but don't stop the problem. The best way I've found is to ground the wire under my hat to neutralize that mechanical energy. That with the rubber bands does a pretty good job. I've always wondered if a mold would stop this.

Two short questions:

 

1. As you said straight cables aren't a problem for over ear use. Just wanted to confirm, as i do not need the microphones. 

http://www.amazon.com/Shure-EAC64BK-Detachable-Earphone-Earphones/dp/B0046HADYQ/ref=sr_1_2?s=musical-instruments&ie=UTF8&qid=1424895816&sr=1-2&keywords=Shure+cable

 

2. Does the adapter's Westone cable version work the same way? Just to reconfirm in case I go for this.

http://www.ebay.com/itm/290630811020?rmvSB=true

 

What do the versions mean?

Which version is the most reliable (connector wise)?

 

Again, Kudos.

Thanks.
