I've come to expect nothing but exceptional quality from Tripowin and the Sirene is no exception. This cable is well made and simply beautiful. The wire is colored with alternating stripes of red, blue, and silver, and from a distance looks like a shiny purply-blue. The 4-core cable is braided in a continuous twist and looks very similar in style to the stock cable that comes with the Dunu Titan S. With fewer and thicker cores, the Sirene isn't as soft and compliant as the Zonie and has more of a tendency for memory, but that's not necessarily a good or bad things, just a matter of preference.
Overall the Sirene is a great way to upgrade the looks of your IEM.
