EQ headphones

 

A lot of talk about EQ (equalizing) headphones on audio forums.
Headphones do measure different.
The most striking one is the frequency response.
Loudspeakers are “straight” over a large frequency range (plus/min 3 dB).
Compared with them headphones are all over the place.
An option is to use EQ and apply a correction curve to get a straight  frequency response.

 

Morphit

 

Morphit offers a correction mode.
For each headphone in the list there is a correction curve.
However, it takes matters a bit further.
If you can EQ  the frequency response to flat, you can also EQ it to a frequency response as characteristic of a another headphone.
This is what the Simulate mode does.
Select the headphone you are using.
Choose “Generic studio reference” and you get the correction curve for the headphone you are using.
Choose any other headphone and you get the frequency response of this headphone.

 

First I let it correct the response of the HD800
Makes a slight difference.
The I used the compare functionality by emulating a Etymotic ERP4P
Indeed the sound changes and get that lean and mean characteristic of the ERP4P
I had the feeling it is a bit overdone.
Than I did the opposite, using the ERP4P, I let Morphit emulate the HD800
Indeed you get the wider soundstage, a bit warmer sound but I’m not really convinced  this sounds exactly like the HD800.
But I do think it gives you at least a taste of how other headphones sound.
Nice toy.
