Acoustic performance is not something that can be simply measured in decibels–with in ear-monitors, it is also a perceived sensation.
Insertion loss, or the amount of natural gain lost by inserting a device into the ear, has to be recreated with an in-ear monitor. How your monitor does this affects the performance. The resonant peak (the ear’s natural ability to amplify a certain frequency over all others) of one person’s ear canal may peak at 2k and another person at 3.5k. When you remove this natural peak by inserting something into the ear canal the sound changes differently depending on the person. The bottom line is that one device will not work perfectly for everyone. Enter the Variable Equalization (VQ) System. 
We started by applying our knowledge of the acoustics of the ear.
The shape of the ear canal varies from person to person. The length and diameter of the ear canal changes the acoustics of the sound environment. For the same reason a bell rings at a certain tone based on its size and shape, the ear canal can increase or resonate certain tones (Resonant Frequency) more than others. This is why some people hear a tone as light and shimmery while others hear it as tinny and harsh.
The reason a loudspeaker may sound great in your living room and horrible in your garage is acoustics. The ear is not any different, and the environment varies for every person. The VQ System lets you make the necessary corrections easily.
Our multi-platform VQ System allows you to adjust our single balanced-armature driver to your personal taste.
Instead of adding multiple drivers and the necessary passive-crossovers which add color or distortion, we used a different approach. We started with a subminiature, ultra-wide band balanced single armature driver and developed the VQ System to acoustically alter the frequency response to personalize your music.
We designed the VQ System specifically for this incredible driver; because music is personal and the headphones should never get in the way.
