It seemed to go well. I went in prior to ask if they provide the service and noticed they actually carry a line of musician CIEM's and plugs (can't recall name). So they do have experience with this sort of thing, and they are listed among the network of audiologists by Etymotic and ACS which hopefully says something. I brought in the instruction page from Heir's website that details the mold requirements (material, depth, mouth position) and she seemed to have followed the process. Although one of my molds got redone (same sitting) as the first developed an air pocket and didnt' go far enough. Second was fine. Shipped both off to Heir's US receiving facility and they were inspected and approved and have since been sent off to China.
Next question now is if the overall fit is good which has me anxious. Probably won't see the 4.A's until mid-to-late next month so fingers crossed. First CIEM's so don't know what to expect.
