Ear Impression Guide

Guide for ear impression for custom IEM manufacturing

What is an Ear Impression?

An ear impression is a silicone mold of your ear canal. This impression is used to create a custom IEM shell that fits your ears perfectly.

  • A certified audiologist captures your ear shape using special silicone
  • Precise impressions determine perfect fit and sound isolation
  • The process takes about 10-15 minutes and is painless

Ear Impression Process

1

Visit a Local Audiologist or ENT Clinic

Our designated branches operate domestically only. Overseas customers should visit a nearby audiologist (hearing care professional), ENT (ear, nose & throat) clinic, or hearing aid center to obtain ear impressions.

2

Ear Examination

The audiologist will check your ear health. Excessive earwax or ear conditions may prevent impression taking.

3

Impression Taking

Special silicone is injected into your ear canal and allowed to set. Both ears are done, taking about 10-15 minutes total. The fee is set by each clinic — please contact the clinic directly.
