They are separate models on the Japanese site. The 3X is the higher version with a better high end and some more refinement.
According to JVC Japan...
High-grade model of U.S. reimportation model "XX" series carbon diaphragm and metal body adopted.
Standard model that achieves deep bass of the force and sound insulation U.S. reimportation model "XX" series
They did what they usually do. Keep better stuff for themselves. Like the S500 is Japan only. They took the US model and added a slightly better version for the home crowd.

Unfortunately these also have the similar peakiness in the upper mids lower highs that are also on the FX1X..If they didn't bother you much on the FX1X these will certainly not be worse than what was on the FX1X.
