Guys can someone please post a link to whatever I would need to do, buy, etc regarding the 23 ohm resister mod? When I search I seem to only come up with radio shack-looking wire resisters that I can't believe are what is actually being discussed. I'm picturing more of a short inline cable adapter or something? I'm kind of excited about this because I'm close to pulling the trigger on the ER3XR, and more than wanting to morph them into a ER4XR, I would love to trigger the highest output on my LG phone. Thanks very very much for any help! (I'm assuming/hoping this qualifies as Deals DISCUSSION )

Anybody check channel balance on ER3? Are they pretty good as ER4? From what I've read, ER4 are made in USA. At these prices I assume are all made outside, but ER4 does come with channel match measurement graph. The main difference comes down to this and the resistor. I saw the response with the resistor and it's identical response.

Yes, I've owned/measured all of them (ER2, 3 and 4 series). They all have pretty good channel matching. The ER4 is tightest, but ER2/3 series are still very accurate to each other.

For a impedance adapter, there are several here: https://penonaudio.com/accessories/earphone-adapters

Here's the discussion on the impedance adapter in ER4 thread. https://www.head-fi.org/threads/if-...-thread-for-you.538615/page-757#post-13938835 It sounds like adapters within the range of 20 to 100 ohms should work. I'm wondering if there is any difference from 23 ohms to other values, and if there is, what's the significance of the difference. Why is specific value of 23 ohms used?

The reason for the addition of 23 ohms specific is that ER3 has 22 ohms in the line, and ER4 has 45 ohms in the line. The difference is 23 ohms. But, why can anything in the range from 20 - 100 added to ER3's 22 ohms can be used? That's what I'm trying to figure out.

You can get an 80 ohm adapter on Amazon if anybody has Prime. https://www.amazon.com/FAAEAL-Conductor-Impedance-Cancelling-Professional/dp/B07FMG8144/

You can add whatever you want. It'll just change the sound to be brighter with more impedance.
