What separates SPEK from other cheaper molds?

Unlike any other DIY ear impressions kits sold in the market, SPEK system's patented design is calibrated to measure the ideal depth of your ear canals accurately and safely.

Other DIY ear impressions often do not provide enough ear canal information, as they generally do not go past the 1st bend of the ear canals. This cannot be used as an ideal ear impressions for custom products because they lead to sound-leak, improper fit and other problems. While they may work as earplugs to isolate noise, they do not make good ear impressions that can lay a foundation for building and investing in a custom product.
