I now like my ER4 so much that I decided to create this thread in order to share my love for this IEM with other Ety users on the forum who still own and love theirs. I feel that nowadays, the ER4 is perhaps one of the most underrated, if not the most underrated IEM on the market. The main complaints are usually that it lacks bass and/or sounds too clean. Personally, I completely disagree with both of these views. I don't think ER4 lacks bass at all and I also don't think that sound can be too clean. In my opinion, the cleaner and more accurate the sound is the better, because it brings you closer to hearing music the way it was recorded. I may be terribly wrong, but I am sure some people will agree and if you do agree with what I wrote above regarding the ER4 and/or want to share your own positive experience with them, this thread is for you!
I haven't heard a high end custom like JH13, but in my humble opinion, the ER4 blows away pretty much every IEM I've heard, including Westone ES3X in timbre accuracy and overall sound quality. I am starting to doubt the need for multi driver IEMs.
