So I just bought a er4p and want to get the adapter to make it er4s. Where is the cheapest one available of good quality?
Hello!
One must be careful with the "P to S" adapter, because not always the sum of the impedances (ER4P earphone + "P to S" adapter) is identical to the original ER4S headphone.
In my case, I found the setup ER4P + "P to S" adapter better than the original ER4S.
I believe that the impedance of my old setup ER4P + "P to S" adapter is greater than the original ER4S headphones.
Cheers,
Peter
as long as the adapter adds 75 ohms of resistance, it'll work fine, no?

After extensive reading of Playback's "Guide to Earphones and Custom-Fit Ear Monitors" guide, the two I've been looking at are the Shure SE-535, and the Westone Truefit 4.
Things I love about the Etys:
1. Incredibly accurate sounding, with no emphasis in any frequency (at least to my ears). Accuracy is paramount to me. I don't like emphasis.
2. Legendary noise isolation - I use these on planes, trains, and crowded cafes and noisy gyms with crappy loud music with no trouble. This is number 2 priority, after accuracy, and I won't buy / use an IEM that doesn't offer perfect sound isolation. It's kind of the point.
3. Mind-blowing durability. I put them through the ringer, and they're still chugging along.
4. Incredible customer support. After 6 years of ownership, they replaced the whole ball of wax for me for $50 when I accidentally damaged them.
5. Ridiculously comfy, and basically water proof, and will not come out of your ears bar nothing.
Things I don't love:

Headphones I use now, and love, after extensive testing are the AKG K702.
P.S. I use my Ety with the "S" cable and a simple BSG amp designed for 600-ohm cans, and the bass is fantastic. It also greatly extends soundstage and opens up the sound. Just so you know...

I posted this info in another thread, and I think that it might be of interest to some of you. If you have an ER4P/PT, try it with a simple passive inline volume control, like the ones made by Shure or Koss, or the cheap one you can buy at Radio Shack. Dial in the resistance until 75 ohms is in series between your player and the rest of the circuit. The result should be very similar to a P-to-S adapter. In fact, it's a lot more flexible. Think of it as a variable P-to-S adapter. If you dial in less resistance, then you'll get a sound somewhere between a 4P and a 4S. You can even get an exaggerated 4S sound with more than 75 ohms.
The effect is similar with other single-driver balanced armature IEMs. The P-to-S adapter colors the sound of most other IEMSs way too much, but with a passive attenuator, just a touch (<10 ohms) makes some of them sound livelier (for example, Soundmagic PL50, Shure E4). Essentially, you're increasing the output impedance of your source. To a point, you can emulate the sound of a player with a higher output impedance (like the HM801). Personally, I like the 4P the way it is, as the adapter increases the response at 2.5kHz to about 5-6 dB above neutral. But you might find the passive volume control interesting anyway.
Is it me or is Amazon no longer carrying the ER-4S? I was about to pick it up for the listed $200 when it disappeared...
Either that or I can pick up the ER4P, but that costs $50 more on Amazon :\
