Is this another thread where you get to finish the sentence?! I love these threads!
No matter how good an IEM sounds, it's a dealbreaker if it's not fun. I'm a huge fan of the Ety ER-4S. But I'm also a huge fan of the PFE232, Shure SE215, Shure SE530, and Westone UM2 as they are very fun sounding IEMs. If I had to HONESTLY answer, my ER-4S barely gets any time compared to my PFE232 and my CIEM only because it's too damn serious... It's truly a work of excellent electro acoustic engineering, but as a PORTABLE DEVICE, I find it's purposes very limited. They marvel at analytical sessions, but who does most of their listening as that..? I have my Vintage AKG cans for that! The reason why I love the PFE232 so much is you get best of both worlds. It sounds extremely accurate and very, very fun as well. The bass is soooo satisfying and the treble I drool over. And the best part is it's extremely well composed and very coordinated.
