Why is there such a huge treble spike in the mid treble in these headphones? It's scaring me and is frequently brought up. Are they trying to target a diffuse field curve? It was clearly not the Harman Kardon curve, so I'm wondering what drove them to do that.
If that wasn't present, I think they would be a lot more popular. I haven't heard these in person, but open back headphones do not usually have the bass response of this. It's a shame that treble is so up there though.
If you ever get to try/owe them. I suggest you try playing around with EqualizerAPO. I'm a teetotaler, but I'd say using an equalizer is like brewing your own beer. And if you're interested (I know no one's interested) here's my brew:
Preamp: -3.5 dB
Filter: ON PK Fc 20 Hz Gain 1.4 dB Q 2
Filter: ON PK Fc 28.25 Hz Gain 1 dB Q 1.8
Filter: ON PK Fc 40 Hz Gain 1.4 dB Q 1.8
Filter: ON PK Fc 200 Hz Gain -2 dB Q 1.625
Filter: ON PK Fc 500 Hz Gain -1 dB Q 1.9092
Filter: ON PK Fc 330.68 Hz Gain -1.5 dB Q 1.3767
Filter: ON PK Fc 1000 Hz Gain 2 dB Q 2.2743
Filter: ON PK Fc 5500 Hz Gain -1 dB Q 2.4036
Filter: ON PK Fc 7000 Hz Gain -1 dB Q 9.3
Filter: ON PK Fc 8000 Hz Gain -0.8 dB Q 3.5
Filter: ON PK Fc 9000 Hz Gain -4 dB Q 5.3
Bass boost
Filter: ON LSC 30 dB Fc 150 Hz Gain 1.5 dB
Filter: ON HS Fc 400 Hz Gain -1.9 dB
It's my EqualizerAPO settings, before the Bass boost note, I'm just inverting the DT-1990 frequency response to my tastes, keeping as much as the clarity as possible. After that it's just a Low shelf filter to get some more bass and high shelf filter to tame the highs a bit. I'm using Topping D30, Violectric V200 and Round velour Brainwavz pads with the mesh cutout. I'm really liking the sound on this setup, I'm trying to emulate the sound I heard on the HE1 two years ago. I know it's apple and oranges, but I'm inching closer. I'm hoping the Chord Hugo I ordered will be able to squish that last ounce of detail out of my music.
