Making a proper set of ear impressions is the first and most critical step in the CIEM process. A good set of impressions will ensure the best fit and seal from your Custom In-Ear Monitors.
Please copy the following impression checklist and give it to an audiologist before they make your ear impressions.
According to Campfire Audio specifications, the impressions must be:
- Full shell impressions clearly include the helix, crus of helix, tragus, and anti-tragus (with no large holes in the concha).
- Made from high viscosity silicone (no powder/liquid impressions), or .stl file format if taken digitally
- Extended to the second bend of the canal open-mouth impressions (using a bite block).
If you already have ear impressions, but they were made more than 2 years ago, we recommend making new impressions due to the nature of the impression material and the natural changing of your ear shape over time.
