I'm currently awaiting my Lune cable, after having gone through two Enyo cables in two years. I don't mistreat my cables, and when they're not in my ears they're rolled up in the Ultimate Ears case.
The first cable I had did not have the multifilament sleeve, nor the ViaBlue connector, and it died nearly a year to the day after I ordered it, so it was thankfully covered by warranty. I sent the cable in with no hassle, and then waited about FOUR MONTHS to receive my replacement cable. Which means that for those four months, a third of the year, I wasn't able to listen to my IEMs, which was quite the shame.
Just recently, my second Enyo cable started giving me problems as well, again, without the multifilament sleeve, but this time with the ViaBlue connector. I thought the connector would stop this one from going the same way as the last, and it might have moved the area of the problem (From being that I could move the cable around the connector to get the channels to drop, to the cable needing to be just so for the channels to drop, which makes it horrible for walking...) but the problem is still there. This time, I decided against trying to replace it under warranty, just for the fact that it would take so darn long, and I decided to upgrade to the Lune cable.
So, I'm currently awaiting my Lune cable (With multifilament sleeve) with baited breath. Which I love most everything about the cable, the lack of durability is my main gripe (The other being the ultra-thin wires slipping in and out of my winter coats zipper teeth.* I also decided to try the right-angle jack instead of the straight, to see if it would tug less at the part where the cable meets the 3.5mm jack. Of course, after paying my package only shipped a few weeks later, and it's been about 2-3 weeks in transit, so maybe the time difference isn't that different from the warranty. All I can say is that I hope this cable lasts me longer than my last two, because I'm done doing business with Null Audio Studio.
Anyway, that's enough of my rant. I enjoyed reading your review, and you took some gorgeous pictures. Good luck, and enjoy your cables because like you said, they are great cables, aside from build quality issues. Keep us posted on how yours hold up!
* Not that I'm zipping up over the cable, I would never. But I don't zip my jacket all the way up, and the cable catches in the teeth sometimes. Also, I don't believe this is the cause of my issues with the cable, as the problem lies further down the cable.
