Regarding getting CIEMs fast in your hands/ears, Westone has one week turn around from the time they receive your in-ear molds. Re-fitment took 3 days to get back to me. And as you probably know, Westone co-developed and also manufactured the early Ultimate Ears headphones by Jerry Harvey. It's one twisted bio story
