Well as many of you might have figured and/or predicted my recent mad EQ experimentation with my B&O H6s ended in a bloody disaster! I thoroughly confused my brain and tortured my ears with this initial exercise in futility. The distortions royally screwed up my headphone's sound signature making some of my music files and genres totally unlistenable. In fact, I say it nearly went as badly as my ignorant foray into open-backs (via LCD-2s)...
the hearing-impaired + chatty Siamese women + Thai tv soaps 24/7 ≠ open-backs!
I received some helpful advice from
@zambz and enlightenment from a few other members and soon realized that I really had no idea what I was doing so I decided to study up on the Harman Target Response Curve; headphone response measurements; parametric eqs; and headphone eq’ing techniques for an entire night and day… especially learning a lot from the following

I then studied Tyll’s headphone frequency response plot and square wave measurements for the
B&O H6 v.1
After some momentous foobar2k plugin crashes and extension hiccups I finally managed to find and successfully cooperate with a parametric equalizer (hooray for me!): Kjaerhus Audio’s Golden Equalizer (GEQ-7S) via Foobar2000 VST 2.4 adapter extension. With very pleasing and satisfactorily results I believe I was able to correct/adjust the five (5) known and concerning signature hiccups on my first generation B&O H6s as follows:
20 – 250 Hz (Two Corrections)
The H6 v.1’s very nice upward transition into the bass from 250 Hz to 20 Hz is interrupted by a strange and very sharp 5dB dip at 165-170 kHz and a 2+dB peak at 125-130 Hz; both were corrected to smooth out this upward curve.
250 Hz – 3 kHz (One Correction / One Adjustment )
The H6 v.1’s long and smooth linear rise from 250 Hz to 3 kHz is interrupted by a slight ~2db peak at exactly 1 kHz and a minor 3db dip at 2.6 kHz; both were corrected to smooth out this otherwise excellent rise.
3 kHz – 22 kHz (One Correction)
The H6 v.1's treble in the top octave above 10 kHz runs a little hot with a significant spike (peak) at 17-17.5 kHz so I lowered this by 8db to settle it down. The second peak in the response at 8-10 kHz is normal for many headphones (Staxs; LCDs; HD800; HD600) and is thought to be due to an ear canal resonance… all the adjustments I made didn’t seem to help any and besides it is more than 5 db under the 0db line and doesn’t sound bad to me so I just left this peak alone.
