IEM cable balancing standards - Westone-styled vs UE-styled of wiring??

post #1 of 2
Thread Starter 

Hi all,

 

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

Got my answer from a few cable makers. Seems there are differences.

 

1) JH, Westone, Unique Melody, Tralucent follow a particular standard in the pin orientation

2) Ultimate Ears, Rhapsodio follow the "opposite" pin orientation as per pix.

 

Therefore when buying other branded IEMs (Aurisonics, Heir Audio, Frogbeats, etc), please do feel free to update me on which standard that IEM brand follows. This will matter for the 3rd party cable makers especially if they have a fixed orientation memory wire (such as the Beat Audio Cronus cables).
