Jesus Christ!
I just replaced the original KZ cable by the HiFiHear one:
1. It is so soft, in a good way, almost like touching velvet or silk. So relaxing and satisfying to touch.
2. It also goes very smooth all along its path, meaning it weights and doesn't curve or fight gravity. It is very flexible, not "rigid", which is extremely comfy and handy to use.
3. The quality of the materials is amazing, I can't say anything wrong, and it looks even better in real life than in the pictures.
4. Every little detail is perfect, plus the 90º jack plug with the little extra height that makes it compatible with smartphones with thick cases. Love it. Even the Y split ring is very useful, never really used that until now. There is one design problem though: there's "no protection" against cable being flexed 90º at the jack plug joint. The black rubber at the end is very hard to work as a protector against this. That means you can physically store the cable in a very bad position, like the cable at the jack end bent 90º, which will totally damage the cable there, overtime.
5. Although one could think that it's not recommended for hooked IEMs since it does not have any hook tube next to the pins, after using it I can say I prefer this a thousand times over pre-hooked cables. Since this cable is so flexible, it adapts perfectly to your ear. It's a little harder to put on since the pre-made hook helps, but that's just... nothing to worry about.
I can't believe these are at $15. It's a steal! I would gladly pay $50 for this cable, even more if you ask me. It's the price I would sell a cable like this if I was the one making it. I remember the day I bought the KZ ZS7 and though the KZ cable was fantastic. The first days it seems to be perfect and durable, but after a few weeks you realize it's a cheap poor cable, at least compared to these. I hope it stays this way and doesn't surprise me with things like the cable going rusty or green, the cable going much more rigid, or the ends getting damaged do to the lack of protection.
Anyway, one question, at the pin end, there is one color dot in one of the pins:
I believe those are there so you can plug in the cable in both sides with the dots in the same side, that way you don't make your IEM out of phase. Now, the question is... does it matter if the dot is pointing to the rear or front side of the IEM?
I hope you get what I mean.
