Got the Rx18Ps (white) on my first try. They don't look like much, but for a pair of cheap pocket-carry headphones, they sound fine (no shaking until around 25Hz). It was a failed gamble but still can't complain at the price (but would hardly presume to claim they are "IEMs").
BlueCrownedThis begs the question what counts as a monitor. I would say cheepo earbud drivers don't qualify as monitors are generally accepted to be higher quality with a neutral profile. I think that we can agree that while you can probably find some people that will agree with MEE's marketing department that these are IEMs, no one that gives a damn about words having meaning would agree.
siddacious"In-ear monitors (IEMs) are devices used by musicians, audio engineers and audiophiles to listen to music or to hear a personal mix of vocals and stage instrumentation for live performance or recording studio mixing."
Make of that what you will.
