The BGVP NS9 IEMs I ordered came with an MMCX cable that was a bit janky (poor fit on the right bud), so I decided to pick up one of these cables as a replacement.
Just taking it out of its HiFiGo packaging was nice - I immediately could tell from its heft and flexibility that this is solid silver and not plated copper. It feels like string more than wire, but in a good way. The only issue was its lack of ear hooks at the individual ends. I actually didn't mind it too much, which is why I only took off 0.5 of a star.
As far as sound goes, I didn't notice much of a change. I also tried them on my Etymotic ER2XRs and didn't hear any significant difference.
The Shozy Rouge IEMs I ordered came with a 0.78 cable that has incredible shape retention, so based on my experience with the MMCX version mentioned previously I decided to try another one for these IEMs.
This second one offered the same unboxing experience, but actually has ear hooks.
As for this one's sound, it certainly seems "hotter" in the treble. Still no sibilance, just a bit of added prominence, I've since gotten used to it, so maybe it was just my imagination.
I would recommend this cable to anyone seeking a higher quality cable than what their IEMs originally came with.
