Can u make a EQ profil for HD600 to sound like 6xx? :sweat_smile:

Hahaha, I’d say just reducing a bit of treble with a shelf around 2500 Hz and a Q of 0.4 should accomplish that fairly easily.

Oooooooook. So. This headphone is Weird™

like… really weird

I have a few measurements now and can provide a preset, but the positioning sensitivity on this design is fairly high, so please make sure your ear is sitting towards the rear of the ear cup/the headphone is pushed forward and low on your head. If not, this likely won’t sound very good.

Hell, even with this preset it probably won’t sound that much better.

I have to say, this is a design I think is fundamentally flawed in numerous ways, and if you have this headphone I earnestly recommend trying to return it and buying something more normal. This preset won’t match the “target” precisely, because the unit I have on hand sounds bad if I don’t go quite a bit further with the upper midrange cuts. So keep that in mind; you will need to adjust manually above 2 kHz or so.

That said, here’s the preset:

Grell OAE-1

Confidence: LOWEST

Uses data from 5128, Clone KB50xx, Clone KB006x

Preamp: -6.0 dB

Filter 6: ON PK Fc 3200 Hz Gain -2.0 dB Q 2.000
Filter 7: ON PK Fc 4750 Hz Gain -9.5 dB Q 1.800
Filter 8: ON PK Fc 5900 Hz Gain 10.0 dB Q 3.200
Filter 9: ON HSC Fc 9900 Hz Gain -5.0 dB Q 2.000
Filter 10: OFF LSC Fc 105 Hz Gain 0.0 dB Q 0.700
Filter 11: OFF HSC Fc 2500 Hz Gain 0.0 dB Q 0.400

Adjust filter 6 for raspiness
Adjust filter 7 for glare/scratchiness
Adjust filter 8 for fixing the ridiculous hole in this area
Adjust filter 9 for adjusting the balance between mid treble and upper treble
Adjust (and enable) filter 10 for overall bass
Adjust (and enable) filter 11 for overall treble

Good luck, and please please make your own adjustments in the treble above 2 kHz and bass. It is necessary.

Would it be possible to do 3 different q values at the same freq, just to educate us how they affect the respons.? Eager to learn.

cheers
Mike

From the JRiver MediaCenter Wiki:

Green line is flat at 99 dB.

Red, blue, and gold lines all show peak filters centered at 500 Hz, +6 dB gain, with varying Q factors. The red line is for Q=1, the blue line is for Q=2, and the gold line is for Q=5.

So, as you can see, higher Q provides a narrower peak and lower Q provides a broader peak. Q doesn’t change the height (gain) just the range of frequencies influenced.

Ha ha! Thanks for the cautions. I’m not convinced Harman is an appropriate target for these, I just want to experiment. I think EQing them is going to be a challenge as they seem to be sensitive to both individual HRTF and placement.

Sure I can see doing that if this was my only headphone. But since I own a few better choices if I want to maximize, say, timbre or detail, I’m going to keep these for their unique staging.

Looking forward to a Headphones.com review, even if it is negative.
