Beware of ****.
Below are the frequency response of 4 **** UEs bought to NiceHCK along several months (raw measurements with source calibration, but not compensated; useful for comparisons, all were measured in a row, with exact same conditions; source: iBasso D14, calibrated; micro: Dayton Audio iMM-6; soundcard: Realtek ALC888).
The issues go across imbalance between left and right, lows and highs roll-off, and defective balanced armature (harsh peaks and excessive dips in highs and upper mids). This could suggest very low quality control of the drivers used (both dynamic and balanced armature); now I doubt the BA used is a true Knowles 30042 (and if it is, many are defective). And this could explain why some people find excessive harshness and sibilance in their **** (UEs, 4in1, DT2, etc.), while others don't.
First, comparison of 4 **** UEs (left and right averaged):
Now, individuals, left and right exposed.
**** UEs (camo):
Despite of the lows imbalance (sub-bass, 5dB at 30Hz, 2.5dB at 60Hz), these are my favorite. I love their sound.
**** UEs (blue 1):
No lows imbalance, but highs imbalance and roll-off, specially one driver (-10dB at 10KHz peak), and roll-off from that frequency (it is more than -20dB at 13KHz!). This is not very noticeable if you have difficulties to hear beyond 10KHz. No harshness in these ones, of course.
**** UEs (blue 2):
These are very similar to camo ones. Lows imbalance, but very good overall.
**** UEs (blue 4, clearly defective to my ears):
Note the horrible dip near 7KHz, and the excessive peak at 10KHz in one driver. 7KHz frequency is audible by everyone. I can't raise volume with these ones: although I'm not treble sensitive, highs are like knives to my ears, and sound strange.
When I ordered 1st ones, I received **** UE (only 1 dynamic driver, no BA) instead. Jim sent me the right ones later.
When the order of **** UEs (blue 1) arrived, after a month, they were missed in the package! I had to wait another month for them.
**** UEs (blue 3 and 4) took 66 days to arrive. And blue 4 is defective. If I want a replacement or a refund, I have to wait they check the defective one. I don't want to wait 2 months more.
So I'll never order to NiceHCK anymore (months ago, there were not problems, but pray to not get issues with them now: they use the fools and delay play -you have to repeat your story one hundred times-, they use the post carrier they like, regardless your choice, they mark your order as shipped when it's not, etc., etc.), and I'll never order a **** anymore (it's a lottery).
Now, when a Chinese seller starts calling me "my friend", like the banned seller and Jim use to do, i start shivering because i know it's the beginning of another horrible "friendship".
This explains so much regarding **** and the love/hate impressions we're seeing.
I don't foresee myself buying any more **** products in the near future. Nor will I be purchasing from NiceHCK anymore since they're left me high and dry. I'm shipping my DT2+ off to another Head-fi'er today to have them take a listen and hopefully confirm my impressions of the pair I have.
