I'm looking to get my first "real" pair of IEMs. I'm upgrading from the Shure E2C and Ety MC5. I've liked them both, but I'm willing to shell out more for something better now (up to $300). My requirements are superior sound and the best noise noise isolation I can get. I've been really enjoying the MC5's with Comply tips for a few months now, so I figure the ER4P (or PT) will be even better.
I will be using these for studying and without an amp.
I am open to suggestions for other brands/iems, but I know I can't go wrong with the ER4P from what I've read.
Thanks in advance.
