All sales are considered final upon final order agreement and payment is received. Our products are sold with a 2 year limited warranty. The warranty covers technical and functional production errors from the time of delivery. Damages from normal use, regular wear and tear e.g. cable breakage, wax or moisture damage, blown speakers etc. are not covered by the warranty.

Custom made in-ear monitors and hands-free kits are sold with a 1 month warranty on fit. Be aware that we might reject or demand new and/or better ear impressions if we consider the ones received not proper for further processing. This can be due to voids, improper fill, too short canal or similar shortcomings in the impression material. Only one remake job is included in the warranty. 

Regarding ear impressions;

We recommend the use of a bite block when you get the ear impressions taken. The impressions should be long enough to include or go just past the second bend, and fill the complete outer ear. On the outside the material should fill enough of the outer ear to leave a flat or a convex surface, without voids.
