Step-by-step Order Guide
How to order custom-fit earphones, tips and plugs
Taking your ear impression
We strongly advise you to get your ear impression taken from a professionally certified audiologist. Please take the following precautions:
Use of biting block is required for tighter fitment. Make sure that the impressions are extended beyond 2nd bend of ear canal (indicated as yellow). Make sure that the extended area (indicated as white arrow) has at least 10mm of space. Make sure to fill the area indicated as blue.
Taking your ear impression at home (optional)
Alternatively, you can use our SPEK (Self Precision Ear-impression Kit) System to take your ear impression yourself in the comfort of your home.
Sending your ear impression
Ship the completed ear impression along with a copy of your order confirmation to the following address. Make sure to keep the package well protected so that the impression will not be damaged during transit.

REFIT / WARRANTY / DELIVERY
Depending on the back-orders, the delivery lead time may extend up to 8 weeks (for CIEM) and 4 weeks (for Eartune tips and plugs) after receiving your ear impression. We recommend that you inquire the production lead time prior to placing your order.
Due to the nature of the CIEM manufacturing process, refunds are not accepted.
Our standard manufacture's warranty covers manufacturing defect up to 3-year after purchase. Take note that the shape of your ear canal may change due to growth / aging, and your CIEM may need re-shelling after 2-3 years from the manufacturing date.
We will accept refit-claim resulting from poor fitment within the 30 days of delivery. Please make sure to contact us via email@example.com to begin refit process.
Our warranty policy does not cover re-shelling after the initial 30 days from the delivery.
