Hello all Q701/K701/K702 owners. Today I'm going to be discussing a very "taboo" topic amongst many head-fi aficionados - Equalizing headphones. If you find your headphones lacking in the bass department, there is something you could do to make your Q's and probably your K's sound like they've got a sub woofer built into them. These headphones are capable of handling bass extremely well if Equalized correctly. I find the bass more controlled than my HD650's which tend to get a little flabby at times.
Here's what you will need:
A decent DAC + headphone amp - I'm using the HRT Musicstreamer 2 + and the m-stage (set to a gain of +20dB)
Jriver Media Center
Now that you've got everything setup, you will need to make the following changes in Jriver Media Center. I use Foobar 2K as my primary player and i do prefer a flat response. However, i do sometimes like a bit more bass on some songs and find that Foobar's EQ introduces far too much distortion. The JMC EQ is cleaner and more effective if used correctly.
I'm going to make this as brief as possible as I'm not a big fan of writing.
First, in JMC, navigate to Tools -> Options
Next, select DSP & output format....
Highlight Equalizer and set the preamp gain to -7dB. This will prevent distortion caused by clipping.
Leave all other frequencies flat at 0dB.
The next part is the most important and customizable.
Highlight Parametric equalizer and navigate to add -> Adjust a frequency (equalizer filter)
You will need to do this 6 times to boost 6 different frequencies.
Note: you could experiment with different frequencies that you would like to boost.
I find the following settings give my Q's a real kick in the sub frequencies
1. Frequency - 20Hz
Gain - +6dB
2. Frequency - 30Hz
Gain - +5dB
3. Frequency - 40Hz
Gain - +4dB
4. Frequency - 50Hz
Gain - +3dB
5. Frequency - 60Hz
Gain - +2dB
6. Frequency - 70Hz
Gain - +1dB
By carrying out the above adjustments, you might find that some detail in the higher frequencies are lost. This however is due to the reduction in the preamp gain to -7dB. You will need to increase the gain (or volume) of your amp to restore the most of the detail in the higher frequencies.
Let me know how it goes guys.
Remember, you don't have to do this if you don't want to.
