Browsing the used items section on Head-fi, you will find people are dumping their custom IEMs for quite a reasonable amount of money. Among them are the legendary UE11 Pro Custom IEMs which is about $1100 new. I found two UE11 Pros for $315 and $375. This is a good time to be buying custom IEMs.

PS: Apparently companies like UE (and a few others which I can’t remember at the moment) will remold these custom IEMs.
