I've been reading for days to decide on my first pair of CIEMs and it seems like the more I read the more I hesitate. I currently use the 535s and I really like the isolation and sound, so I thought that CIEMs would give me more of all that I enjoy, but... The more I read the more I complaints I come across about getting a good mold from an audiologist. I live in NH and it seems the audiologists, even though recommended by Westone, or JHAudio, are not inspiring my confidence. I'm real reluctant to spend over a kilobuck and then have the experience ruined by the $50 setup process. So, here is my question: Is that a valid concern? What percent of users have had to send back their monitors for a refit? I realize that this is a guess, but head-fiers will make the best educated guess! How many of you just gave up because you couldn't get the fit right? I guess what I'm looking for is a bit of reassurance that the trouble to get CIEMs is worth it. Thanks in advance for your help.
