When Klipsch released its first IEM (X10) a few years ago, it was nothing but awe from the community. But things took a turn for the worst when they decided to release variants of the S4 instead of bringing true innovation to the tablet. Even the Reference S4 is not what I'll call an upgrade over the original S4. The good news is, they are coming out with a new X series IEM called the X7i, supposedly a step down model from X10i featuring a proprietary single BA driver, ceramic housing and price tag of $200. Let's hope it will bring back the glory days.
