Spiral Ear specialises in the manufacture of soft-shell custom in-
ear monitors. We have also expanded into the universal IEM
market, and some of our custom models are available in
universal-fit versions as well.
All custom-fit in-ear monitors designed by Spiral Ear are hand-
crafted and utilise soft, medical-grade silicone. Thanks to its
flexibility, the material naturally adapts to the unique anatomy of
your ears, providing one of the highest and most consistent seals
possible—resulting in excellent isolation from ambient noise.
In addition, silicone adapts more easily and comfortably to
changes in the ear canal than typical hard materials, minimising
fit variations caused by natural jaw and muscle movements. As a
result, silicone delivers the ultimate fit and long-term comfort.
