IN-EAR MONITORS | IEC-711 Compliant Coupler

My newer IEM reviews all feature IEC-711 compliant measurements which use a generic coupler that meets the industry standard for Earphone measurements. Data shown will be in complete raw formatting.


All of my personal measurements are performed using the MiniDSP EARS measurement rig. This rig works quite well but it does have limitations. It also is not industry standard. So please take all measurements with a grain of salt.

In particular, the EARS does have issues with measurements around 4-5 KHz. With most all measurement devices, anything past 10-15KHz can have a lot of scatter. There is also possible noise induced measurements in the lower and sub-bass regions (below 40Hz).

For my measurements, I try to take at least 5 measurements on each ear at varying positions, and use what I consider the best middle ground of the two. I follow up with my own listening to verify if it sounds like it measures as best as I can.

There are several compensation curves that may be shown.

For IEMs, the compensation curve I typically show is the IEM Diffuse Field compensation provided by MiniDSP, which is loosely based of the Etymotics ER4 IEM and Harman Targets.

For Headphones, the curves is the HEQ from MiniDSP. This one is based on Harman Target curves. 

I do sometimes use my own compensation curve which is a hybrid of the Harman 2018 Target curve and the 2013 standard, which was based off of Speaker compensation in a diffuse field.

Music Genres:

I listen to music across a wide array of genres. I primarily listen to rock, jazz, instrumental stuff, and folk/bluegrass/country. I also try to mix in some hip hop, EDM, and pop music into my review time depending on the headphone. 

Sound Signature:

My preferred sound signature is a neutral signature with a lean towards slightly bright, which provides more intricate details and more airy presentation. I prefer my bass to be linear with a very slight warm boost. If you have heard the Focal Elex or the Hifiman HE560, that is what I like the most. The mids are also just a shade recessed to provide a wider soundstage. But I am also okay with a shade boosted to provide intimacy a la Focal.
