I've recently come across a strange problem with my IEM and balanced cable. The balanced cable is the Beat Audio Cronus which was balanced by Beat Audio themselves using the Kobiconn connector (SR-71b/Protector/Rx Mk3). I've used that very cable with my former UM Merlins, SE530x8, and Tralucent 1Plus2 and not had any issues with the polarity and phase. All was good. Using SE cables with those IEMs were also good.
I recently had a new IEM (not mentioning names yet, giving the maker a chance to do some investigation), and that new IEM came with it's own SE cables. They sound fine with their SE cables. However when I use my Beat Audio Cronus, they are out of phase. So my immediate thought is the socket orientation is inverted in the IEMs. However talking to the maker, he believes they are built correctly in accordance to the UE standard. He further mentioned to make sure that the balanced cable matches the UE standard, not Westone's
Therefore this leads me to the question. Is there a standard to pin orientation and socket orientation for both the cables and the IEMs? Is there truly a "UE-styled" of cable balancing vs "Westone-styled" of cable balancing? Or was my IEM just manufactured incorrectly?
Any advice (esp from experienced cable makers) will be truly appreciated.
Left IEM: lower pin is ground upper pin is left
Right IEM: lower pin is right, upper pin is ground
edit: I don't know why pins are noted as left and right as I would have thought it would just be positive/negative
