This review is a comparative of the following cables from
NiceHCK :
Build quality :
Overall build quality on both cables is extremely good, plugs are somewhat different, while I enjoy them both, I found the plug from the 8 cores to be better (the carbon sticker finish looks good and it looks sturdy). The plug on the 7N is more known, as we can find it on many cables. It is a clone of Oyaide, but I checked it and it is almost the exact same dimensions. It is not a first price of fake oyaide we can generally find on the market, still not an official but a good one.
While the transparent « ball »-like (which is here for just the fun and beauty) are identical on both cables, the splitters themselves are different. The 7N one use a splitter that I never faced until now, great finish (glossy metal, well finished). On the 8 cores one, it looks a bit similar to the plug, without the carbon sticker this time, great finish too. No trace of glue, or anything badly cutted like we can generally find on cheaper cables, the finition is exceptionnal. Clearly, both of these looks high-end cables.
They remains the same design, with a red mark to help separate right and left (which is nice), Left has no color, but just a transparent clip before the connector himself (I prefer this to the usual blue or green for the left, much more stylish). They are identical but the 7N have glossy finish on them, while the 8 cores is matte finish. Just a matter of preference. Personally I like them both, maybe the glossy one is more sensitive to scratches with time.
The 7N cable is supposed to be a pure single crystal copper OCC silver plated, I say supposed as we don’t really know if it’s true (like all cables anyway). I asked to Jim but unfortunately he can’t say more than the product page itself which don’t precise this information. So, I don’t really know how much wires per cores, milimeters, etc. Overall it looks really good, the cable is extremely thick (much more than I thought initially), feels sturdy. It is soft but not much flexible. It is acceptably stiff I would say. I used my water boil technique to soft it a bit more, it worked. I’m more pleased like that, even if it could be better. This crazy thickness brings the best conductivity experience I’ve ever had, and the best among the two. I would say anyway that conductivity is generally better on a good thick 4 cores than a thin 8 cores. I really like the look of the cable itself, even if my only reproach is on its stiffness side only.
The 8 cores is using pure silver (or is supposed to be, here also). No technical specs /infos here also, unfortunately. The cable is extremely soft and nicely braided. Cors are not that thin nor thick, I would dedscribe them as mediumly thin. The shiny white look is very good, and breathe the high-end. A true success.
Overall, I like them two, hard to choose which one is the best for overall look. Depends of personal preferences. If you are walking much with your cable, then go for the 8 cores, but if you are at home/work and don’t move your head much, then go for the 7N.
The 7N is the less microphonic of the two.
Note that I removed the earguides as I use my standard earbuds with MMCX that I did (a personal EMX500 DIY that I did by myself, and which will help me differenciate them especially for my sound impressions below).
Sound impressions :
To be honest, I wasn’t a real cable believer until I finally get those two cables. After spending many hours with both cables, I can easily discern them and I can confirm there is clearly a difference between them.
While the 7N is more analytical and has a more intimate presentation, the 8 cores is more spacious. But overall, they shares the same soundstage which is deep and large when it needs to be. Also, soundstage is a slightlymore narrower on the 7N, while the 8 cores has a bit more natural approach.
The 7N brings the best of details from the two, highs are and preserved with excellent sparkling and micro-details, while the 8 cores polish high frequencies and smooth them out, making this cable more relaxing listening than the 7N. Overall, I find the whole frequencies to be much smoothed on the 8 cores (silver effect). Subbass and bass are much in favor of the 7N, clearly. Overall bass presentation is more forwarded with authority on the 7N, while it is cleaner on the 8 cores. I feel like mids are very good on both, nice presence, great vocals, not grainy at all. I feel like it deletes the little grainy effect my reference had with my usual bad quality cables, stunning !
Differences between the two only plays mainly on bass and highs, and soundstage presentation.
Conclusion :
[ My own yet best DIY earbuds equipped with the 8 cores ]
Overall, depending on mood, I have to say I’m much pleased of the peformances of the two. If I feel nervous and want a relaxing listening, I go for the 8 cores, while sometimes I need some energy and analytical listening, then I switch to the 7N. For those who knows NiceHCK EBX earuds, I would say it is the best companion coupled with the 7N cable, ever. It will wake up bass (that was lacking with their stock cable) and you will appreciate even more the details provided by those very good earbuds.
NiceHCK did a great job on both of them. Those are now my reference cables. Highly recommended, even more for the price asked.
This is my first ever cable review ever done, hope you enjoyed it 
(and sorry for my limited english, not native)
Cheers'
