Quality Components Only
Our engineers handpick every component to give you the best-in-class offerings. We fine tune and assemble them to ensure that they sync up nicely with a <1% error tolerance. IEMs are frequency tested using a 711 occluded ear simulator for accuracy and replicability. When you choose an IEM made by us, you own a piece of SG Engineering.

High Tech Assembly
Consistency is key in our sound design and tuning. To achieve this, we use advanced 3D modeling technology to orientate all drivers, acoustic chambers, and circuit components. By boolean subtracting these components from your full-solid earmold scan, we create precise driver slot-ins and 3D-printed sound channels, resulting in unparalleled accuracy and consistency in sound quality.

Biocompatible Materials
Your ear canal lining is sensitive and reaction-prone, so its important to manufacture IEMs with safe materials. FATfreq IEMs are made with high-grade medical resin. It is hard, strong and suitable for biocompatible applications requiring long-term skin or mucosal membrane contact. It is coated with a unique material that is USP Class VI certified, ensuring safety for use within a medical device.

Proprietary 3D Printing Process
FATfreq utilizes advanced digital sculpting and 3D-printing techniques to preserve the intricate details of your ear impressions. Unlike the traditional wax-dip reverse molding process, this cutting-edge method significantly reduces errors, resulting in unparalleled precision and exceptional comfort for your custom in-ear monitors, which are meticulously fine-tuned to the micrometer.
