Jack redesign and tangle free cable makes all the difference!!

Summary: I previously owned a set of S4i 'originals' which were also, amazing. However after a whole 5 years of use and getting tangled up in God knows what the cable join at the jack delaminated, which seemed to be a common problem with Klipsch earphones. Presumably, some of this feedback eventually found its way bay to Klipsch HQ and their team of boffins have at least tried to mitigate these problems.
Summary: I received my Image S4i-IIs on October 24 2014 and today, February 16 2015, the left ear bud has stopped working. 4 months these lasted. While they worked they were pretty decent, the sound quality was quite nice, but I was constantly readjusting them to get the proper seal. I realize fitting things to the multiple shapes and contours of ears is tough, so I won't fault them for that.
I was so happy with the first pair that I wanted another pair ...

Summary: This is my second pair of these headphones. The first pair lasted about 5 years before they started to malfunction, probably from cramming them in the front pocket of my computer bag. I was so happy with the first pair that I wanted another pair just like the first. I am so pleased with the sound quality and the dynamic range of these headphones. The best deal I've found for the price.
