HOW TO REDUCE NOISE. It is important to place the ears DOWN over the ear canals so the ear canals are NOT exposed, then secure them in place w/ Happy Hoodie. Noise reduction is achieved by Happy Hoodie’s gentle compression closing off the ear canal. IF YOU THINK IT'S TOO TIGHT, PLEASE KNOW SNUGNESS IS NECESSARY.
