How Decibullz Work


Decibullz are easy to shape and reshape. Custom is simple, just HEAT. SHAPE. GO.


Attach the smallest silicone tip to one of the molds and drop it into boiling water—one mold at a time. Wait 5 minutes, then safely retrieve with a metal spoon.


Allow mold to cool for 30 seconds.  Then, insert into ear and gently shape to your unique contour. Leave mold in for 2 minutes so it retains the new form once removed.


Once you’ve repeated these two steps for the second mold, adjust the silicone tips as necessary, and enjoy. Re-mold as often as necessary for the perfect fit.
