Ear Impression
Hisenior custom in-ear monitors are full shell products. Therefore, a full impression of the ear is required featuring that must include the full helix,crush of helix,ear canal,cymba,tragus and antitragus. The impressions must be taken with a high-viscosity silicone impression material.
Impressions should be taken past the second bend of the ear canal in the “open mouth” position. In order to accomplish this, a bite block should be used throughout the entire impressions process (beginning when the impressions material is injected into the ear and ending after the impressions material has fully hardened).
