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 read and print 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.
