[QUOTE="Chris Johnson, post: 123977, member: 975"] Re: UE IEM Frequency Response Graphs Drew, you are entirely correct about the effects of the canal. I'm sure an audiologist could tell you exactly what these effects are. As such, measurements really just serve as a comparison. That said though, even the flattest IEMs aren't flat at all compared to reference grade regular headphones. This is down to the limitations of tiny armature drivers. The main advantage of IEMs though is the isolation, which is why in the real world, they seem so impressive. But if you go and sit in a really quiet room and compare good headphones with IEMs, you will be less impressed :-) From a monitor engineering standpoint though, response graphs are useful to show up what you are and aren't hearing. For example, if you find you are cutting 4k on all of your vocal mics, but then discover that your IEMs have a peak in that area, you may want to EQ your PFL output and leave the vocal mics flat.
