All custom-fit In-Ear Monitors designed by Spiral Ear are hand- crafted and utilise soft, medical-grade silicone. This material easily adapts to your ear anatomy due to its inherent flexibility, providing the highest possible level of consistent seal and, consequently, excellent isolation from ambient noise.

In addition, silicone accommodates changes in the ear canal more comfortably and effectively than typical hard materials, minimising fit variations caused by natural jaw and facial muscle movement. As a result, silicone delivers the ultimate custom fit!
