Custom-made in-ears – more commonly known as CIEM (Custom In-Ear Monitors) – are becoming increasingly popular. A few years ago, this was not the case when Ultimate Ears, Jerry Harvey and Compact Monitors still featured high-end products, but universal mass-produced earphones cost less than half the price. This price difference has now almost been closed. A custom-made earphone does not necessarily have to cost more than a good universal earphone such as the Campfire Andromeda or InEar ProPhile 8.
That’s reason enough to look at how a CIEM is created. How does it get its shape? How does the technology get into the custom? To answer these and other questions, we visited the specialists of Vision Ears in Cologne.
