I just got a pair of Westone pro 30s, and have been considering getting custom molds done. There is friendly audiologist around the corner from where I work who has offered to make impressions for a very reasonable price.
Is there any conventional wisdom regarding doing this? I read in the Basic Guide To In Ear Canalphones, "~~custom molded tips can also be ordered to fit universal IEMs (IEMs that are designed to use soft plastic or foam tips)."
I wish I could swing true customs, but I can't. Just wondering if doing custom molds would increase sound quality over foam, and whether there is a downside.
Thank you very much.
