UE-5c was released at 2004, the same year as UE-7 and UE-10 Pro (both two-ways triple drivers). UE first custom, the UE-5 Pro, was released around 1995~1996 as one of the company first product. Super.fi 5 Pro at mid 2005, Triple.fi 10 Pro on late 2006, UE11 Pro was around mid 2007, just before Jerry left UE (as Jerry last project there). IIRC, I first read about JH Audio around early~mid 2008, which was only making custom aviation headset at the time. JH13, along with all the other JH models, came a year later, announced just weeks before CanJam'09.
