Lately, I have been enjoying my new ER4XR IEMs. I have other models but this is the only model I use because it's just far superior than anything I have or have tried in the past. It is just so addictive listening to music and everything else in between using the ER4XR. My ears cannot tell a lie!
My setup. Cowon iAudio 9+ (32GB) with many different genres but mostly listens to classics. JetEffect is set to BBE Headphone EQ setting. Classicals are mostly 44.1KHz sampled lossless as that's the maximum rate it support.
I use Comply deep insertion ear tips and was previously using the Brown filter. I thought it sounded good. I particularly enjoy the Bruch and Tchaikovsky's Violin Concertos, and jazz of course.
I then decided to go one notch up to white (gray is most bright). Wow, what a difference it made. It sounds as if my set up completely changed.
Now I want to try the Gray to see if we can squeeze out a bit more realism so I ordered two sets, Whites and Grays.
Etymotic ear IEM's are like a custom tailored suit. You have to measure and remeasure often to get that perfect fit. I am not kidding. They give you the best in class IEM, now you need to put some of that elbow grease to make it your own.
If you have any doubts whether these work, they surely do, and I highly recommend it if you love classicals and jazz.
