On the other hand, here are the equalization to add midrange.
And these two are the milder versions that I’ve created myself.
If you haven’t had any previous experience with equalization before, I suggest you stick with the preset settings first. Setting a custom EQ requires you to know precisely what frequency band to fix, and people are not born with that knowledge. If you have a trained ears, it shouldn’t be too difficult to get a hold of the EQ game. One of the easiest method to know the different frequency bands is to take one slider, push it to the max, pull it down to the minimum while listening through the headphones and hearing the changes brought by altering that slider.
How well can equalization works depends on a lot of factor. Of course the actual EQ setting itself is of the utmost importance. But the actual system components and recording quality also plays an important part. A good quality neutral recording should respond better to EQ changes than a compressed and overboosted recording. So, this requires a lot of familiarity with your system and your music. A well implemented equalization would give a lot of benefit, and with very minimal loss of quality, even on a highly transparent system like my Zana + HD800 set up.
I invite you to give this a try and post your findings! I’m mostly using Itunes and Ipod, but surely your option is not limited to that.
I probably need to add the fact that EQ is not meant to make a Sennheiser into a Grado. While it works to a certain degree, first you have to make sure that the headphone you own is generally the “correct” signature that you want.
On a slightly different sub-topic: I don’t think the perfect headphone exists — hence the needs of equalization even with something like the HD800. I hope you can see that this is not a flaw of the headphones, but rather caused by the large degree of variations in recordings. To put it simply, on a bright recording, it would be nice to have a dark headphone/amp/source combo. But when the next track is a dark recording, then what sounds beautiful on the previous song will now sound overly dark and veiled. You have no choice but to put in equalization, or change to a bright headphone. But changing headphones also comes with a bunch of other character change, and so I may not want to change headphone because I love the character of this headphone so much, while all it needs is a tweak in the tonal balance. Like in the case of the Lambda Stax: it’s not perfect — it seriously lacks bass body, but the owners love the Lambda sound so much. You’re left with no option but to EQ in a bass boost setting, because even upgrading to the Omega2 won’t give the same open sound that you get on the Lambdas.
