Unlike your size 22 Shaquille O'Neal shoebox full of erector set cables, chargers buttons, batteries, boxes, belts, dials, ear-aching "hearing-aid compatible" headsets and "vanity-endearing" neck loops - HATIS won't be tossed into a dusty bin under your bed along with old back-up hearing aids and atrophied ear molds.
HATIS hearing-aid telephone headsets were designed by the deaf, for the deaf and because a deaf entrepreneur absolutely positively had to understand clearly on all kinds of cell, cordless and landline phones at any hour, in any car, plane or space, anywhere on the planet, to conduct a productive personal and professional life.
