Again, you need to listen for yourself and decide how to apply the EQ. So correcting only the frequency response may not produce the expected result. The headphone designer(s) will have traded off all of those factors when designing the headphone. It's best to start with something that basically sounds good to you. You always need to listen to the result of any EQ based on the measurements, and adjust it so that it sounds right to you.īecause there are a lot of factors affecting the sound of a headphone, you probably won't be able to EQ a headphone you don't like into one that you do.
So, when you run headphone measurements for EQ, it's important to treat the measurements as a guide. Finally, different people have different subjective preferences. Factors such as the positioning of the headphone, the seal of the pad to the head, and so on, will change the measurements. Furthermore, we all have different anatomy: studies show the acoustic signal at the eardrum varying by 5 dB in the bass, for example. Despite their cost, they still produce very different results, as shown in the graphs in this article by Audeze. Professional artificial measurement "heads" attempt to simulate this environment, and as result are very expensive. Sound bounces around in the tiny confined space between the headphones and your ears, and travels down the ear canal until it eventually reaches the eardrum. Unlike a speaker, which can be measured for accuracy in an anechoic chamber, headphones can only be measured when they are on a "head" (either real or artificial).
Headphones (and IEMs) are complicated things when it comes to their acoustics. It determines not just the overall balance of bass, midrange and treble, but also the distribution of harmonics that are part of every musical note.
There are a lot of factors that affect a headphone's sound, but the frequency response is the primary one.

However, the technique can be used with many other devices and also with software implementations, as long as they have a full parametric EQ capability.įor devices that don't have a full parametric EQ or that can't have an REW measurement signal run through them, see the related app note Headphone EQ for iPhone (or Android, or DAP). To implement the EQ, the app note will assume that you have a miniDSP HA-DSP headphone amplifier or another miniDSP device such as the 2x4 HD. In this app note, we will walk through EQ-ing your headphone based on measurements taken with the miniDSP EARS measurement rig.
