Not absulutely sure what "in-ear-monitors" are? I have seen a line drawing
of the Shure one and it does look like the Philips ones I have at the moment
which fall out continuously: This could of course be because the Philips
ones are too heavy? Especialy if all the noise cancelling technology has to
be built in to the head piece.

Ths Philips ones have two rims of convex cups around a central monitor. Is
there a (foam rubber?) noise blocking plug as well? Is the transducer in the
Philips just NBG? It does give quite good highs but that annoying switch
just seems to turn the volume down. Do I need an amplifier or will none of
these things work properly without one as suggested by headphones.com? This
is why I was looking for a comparative and independent review/opinion.


In-ear monitors, if fitted properly, give something like 20
dB supression of outside noises, and are a proven solution
for high quality music listening.
