For people who have ordered kxxs from CN -> EU countries: did you have to pay customs fees? How much %?
Is the kxxs a bad choice for people who don't want harsh treble? If so, what would be the best choice for an iem for someone who's treble sensitive. I'm also looking for closed cans along the same lines.
It would surprise me though, because I've read here and heard elsewhere that they're smooth, and that they're good for long listening sessions, though a few pages back I saw a graph showing spikes in 10 or 12-16 khz (and now same on @crinacle 's site), assuming I understand this correctly, the person said that he wanted to redo the measurements, I'm looking for this now. @WHO23 was the person of the graphs in the thread that I saw.

I'm looking at these as well now and comparing the graphs they are quite similar, is it normal that the upper frequencies spike like this, or does it mean: extended or accentuated or emphasized, or even harsh, or further still sibilant treble?
Thanks
I can't answer about taxing things since i dont live in Europe and I dont have KXXS but I do have it older brother Kanas Pro, they are not treble sensitive, they are not even considered to be bright iem to me. A lot of people sometimes can't really know what is the exact frequency that bother them, easier to describe is divide into 3 section which are general bass-mids-trebles.
KP or KXXS dont suffer from bright trebles, they have sparkles with nice extension, boosted a little on 8khz is a normal to perceive sparkles, same with other iem even on TOTL iem.
what i heard from KP is just a little bit shouty (which some people explain them as sibilance or highs) but actually that on 3khz hump, and can be heard through female vocals on shouts, cellos, harmonica that reach that 3khz frequency especially in high volume.
While the graphic from crin mimic what I'm hearing about KP, that 16khz boost is a normal also, you wont hear any sibilance from 16khz. 16khz boost will be heard as "air" make perception of space, air to achieve bigger soundstage image.
going down from there, at 12khz is normally everyone still can hear that clearly, a very high note sparkles, extension of the cymbals, if these frequencies are boosted too much, it will make fatiguing. and about "Ssssss" sibilances, normaly created around 6khz thats why if you are looking on the graph of TOTL iems, alot have dips or a little dips on 3,6,12 khz but boosting on 2 khz for vocal, highmids, 4khz for adding details, 8khz for that sparkles, and 16 khz for air.
