• We require a full impression of each ear that must include the full helix, crus of the helix, tragus and antitragus.

IMPORTANT: The impression MUST be taken completely beyond the second bend of the ear canal.

  • Use only high viscosity silicone impression material when making the impression.
  • Open mouth type impressions are not required, however a 1-2 inch bite block is recommended to reduce jaw movement. It is important that the patient’s jaw remain still in order to yield a fit with an optimal seal.
  • The following images are meant for reference purposes only. We will not accept impressions that are already pre-trimmed. Impressions must include all listed areas to be usable for custom in-ear monitors.







  • Follow this guide to ensure that you will have a usable ear impression that will give you the best and most comfortable fit.
  • Send in your impressions no later than 30 Days after having them made. Impression material changes over time and can impact the fit of your in-ear monitors.
  • After you receive your impressions from the audiologist, take them home and snap a few photos of them in the positions you see below.

Photography requirement





  • Your impressions will not look exactly like the photos above. Do your best to copy the angles that you see. Capturing these specific angles provides us with crucial information about the quality of your impressions.


  • Place your impressions on a background where they are easily visible. Since most impression material is very light in color, a dark surface, table, or countertop works well.
  • Use plenty of light when taking your photos. The more detail we can see, the easier it will be to approve your impressions for use.
