Ear Impression Shipping Guidelines & Important Notes

Step 1｜Request Shipping Address

  • Once your impressions are ready, contact us via direct message (DM) or customer support to obtain our workshop’s current receiving address.

Step 2｜Packaging Instructions

  • Individual Protection: Wrap the left and right impressions separately to prevent them from sticking together or deforming under mutual pressure.
  • Rigid Box Packaging: Place impressions inside a rigid cardboard box packed tightly with bubble wrap or cushioning foam. Do not use soft padded envelopes.
  • Enclose Information Note: Include a legible paper note inside the package with your:Full NamePhone NumberOrder ID / NumberSelected IEM Model

Step 3｜Dispatch & Notification

  • Photo Verification: Take a quick photo of your box contents and enclosed note before sealing the package.
  • Provide Tracking Details: Send us the photo along with your courier tracking number so we can monitor your package in real time.
  • Timely Shipping: Ship your impressions within 3 to 5 days of sampling to prevent natural material contraction or subtle ambient deformation.

Important Notes & Guidelines

  • Impression Condition: Production is strictly based on the physical impressions received. Please ensure thorough packaging to prevent crushing or thermal distortion during transit.
  • Quality Requirements: Impressions must clearly capture the full ear canal, concha, helix, and tragus without missing edges or large air voids. (Singers and live performers are strongly recommended to use a bite block, ensuring impression depth passes the first canal bend).
  • Engineer Review: Our master technicians evaluate all incoming impressions. If an impression lacks required depth or features severe defects, we will contact you to discuss whether a fresh re-take is required.
  • Shipping Expenses: Inbound impression sampling fees and courier shipping costs are paid by the customer; return shipping for the finished CIEMs is covered by DS Audio.
