These were exactly what I had hoped for
I owned a previous version of the Ety ER4's a little over a decade ago, I liked the sound a lot but did not care for the cable noise and the weight of the cable. Sitting perfectly still worked well for me but obviously not an ideal resolution. Eventually I had an issue with one side of the headphones and after they were returned from service (both sides replaced) the sound signature was very different and they fell out of favor (I tried burning them in). Luckily I had my Ety ER6i's (which are probably my favorite all around IEM ever) and listened to them more than any other headphone/IEM I owned. Along came the ER4XR's. Durable, lightweight, much better, lighter, quieter cable and a slight extension on the bass side makes them my new favorite IEM's. The bass extension is not fatiguing in my opinion. Ety, bring back the ER6i's!

Also have a pair of ER•6i, my first “Hi-Fi” headphones of any kind! Purchased at 2005 MacWorld.

great sounding earphone
great sounding earphone, flat and natural sound, silicon tip is painful to insert, but have greater detail once sitting properly. the detail is fantastic. great sound isolation, not as good outside noise suppression compare to active noise cancelling headphone (bose qc 35 II or sony 1000xm2), but still very usable during flight. foam tip is more comfortable, but sacrifice on the detail.

Not as much isolation as my old ER6i set Those were comparatively cheap, and worked great. I was expecting more. The cable insulation gets really stiff in the cold. The bottom end response of the XRs were a little underwhelming. I tried using them with the headphone out of my bass amp for actual in ear monitor use, and it noticeably affected my dynamics when I listened to recorded practice compared to using my Sennheiser HD280 pro over the ear cans.
I lost them, and will not replace them. I'll try something different.

Solid construction and very well built. The deep in-ear insertion takes some getting use to but once you get pass that, the transparency and delivery of the music is par none.
Bass? It is there when it is there in the music and not when it is not.
Any gripes? With the introduction of the MMCX connector for cable replacement, was hoping for the ability to change to my own personal custom cables. Unfortunately, due to the proprietary notch, it makes such options next to impossible. I only hope that Etymotic would produce some adapters or cables for wireless listening to these in the future.

Very neutral and well sealed earphones. I believe it's the most accurate one in the world.

This is a great update to the original IEM. Etymotic mean what they say when they describe their SR as a reference class, it very closely adheres to the measurement driven sound profile of the ER4S.
-THE HISTORY-
Etymotic are primarily a medical equipment company, making high end measurement, hearing aid and protection equipment. They did pioneering research and measurements in the early 80s into the in ear canal hearing response. As a side product of this, they were able to leverage this unique early insight to create what is arguably one of the most accurate heaphone response curves. They already had unparalleled expertise in Balance Armature design for their measurements, and their IEMs featured beautifully tuned single balanced armature drivers (no concerns regarding cross over distortion!). Similarly, they already had good tips for medical grade seals. . . the ER4's 40dB of isolation is the most of any IEM that I am aware of including all custom fits.
-THE SOUND-
When Etymotic say this is a reference headphone, they mean it. You are buying their hearing model, and the ER4 are a mechanical vessel of delivery.
I am pleased to report this new SR model variant retains the exceptional sound performance and closely adheres to the same Etymotic target curve. As an engineer, I LOVE that Etymotic includes measurements of YOUR headphones with the every ER4, so you can compare your classics with both your eyes AND ears :)
-THE NEW MODEL-
Both these new ER4SR /XR as well as the economic ER3 series come with substantial mechanical improvements vs. previous generation. The sound remains blessedly unchanged, but these headphones have been made much more convenient and practical. The cord is replaceable, but it's also much more flexible. Combined with the smaller body size, it's very practical to now wrap the cord behind the ear as with most modern IEMs.
With my ER4S, I had to use the shirt clip to minimize cord self noise (sometimes called microphonics, incorrectly), but still I found heavy bone conduction made these unpleasant for use while extended walking. With the new models, I don't bother with the clip, and the snug new cord management minimizes these effects such that they are a pleasure to take on the go. I'm still not sure I'd recommend them for walking around the city (because of the isolation).
-THE BOTTOM LINE-
If you want accurate in ear headphones, and the prospect of a deep insert doesn't frighten you, just do yourself a favor and buy either these ER4 or the ER3 as your budget allows. The ER4 are made in America and are channel matched to the reference curve to a higher standard, but honestly the ER3 (made in china) are excellent as well.
