been an ETYMOTIC guy for a long time..These IEMs have been around a LONG time. Initially, they were so far ahead of everyone else and they had little competition. Nowadays, other manufacturers have closed the gap, and some have, maybe equaled or surpassed the ER-4 - but at a MUCH higher price point. They've simply been around for TOO long to be continually generating buzz on the forums - and they've remained essentially unchanged since their introduction.
I've been an ER-4 guy for a LONG time, and over the years, I've sold off my pair, to try the newest flavor of the month, only to later buy 'em again. I've done this 3 times. Now that I have a larger discretionary income, I just keep my ER-4 while I try the FOM IEMs (my latest being the Monster Turbine Coppers).
To my ears, no other IEMs have given me greater aural satisfaction than the ER-4. I also use them occasionally on my home rig with the (S) cable attached. I love the absolute clarity and intimacy they bring.
