    Etymotic Research ER4XR reviews

    ER4XR In-Ear Extended Response Earphones is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from G.K As usual Etymotic Research didn't disappoint with its flagship, clear response in all three frequencies, all in its place!. listening almost any genres of hi-res music on the go, at home... I'll not compare them with different gear but I will say having a not small experience with high and SE846--Astell&Kern AK T1p and a few more in ear-over the head headphones.. this model of etimotics is not to far in quality example... I love se846 for every day basis but is kinda hard to use in winter time, i the car, under the coat, when snowboarding, but great for summer time photography (no wires in front of you ;) I'm photographer so the guys with same (disease:D) will understand what I'm talking about... I used to have ER-4PT which I lost it somehow, one more thing I want to mention: if it's used with synthetic clothing you may experience a little microphonic effects (not that critical) now eartips: since I have a previous model eartips was my biggest concern, they didn't work for me, except foam tips... Best tips I had used with phones they were Shure EABKF1-10M... Sorry if made some written mistake, new year days so... :D Happy new year! Cheers
