# 64 Audio

> 64 Audio is a Vancouver, Washington maker of high-end in-ear monitors that started in a Portland spare bedroom in 2010, when sound engineer Vitaliy Belonozhko cannibalized his own earpieces to build a custom pair for his wife. The company now designs and manufactures custom and universal IEMs sold in more than 90 countries, built around two patented ideas - apex, a vent that bleeds off trapped air pressure in a sealed ear canal, and tia, a tubeless driver layout - that address the fatigue and muffled soundstage plaguing older sealed earpieces. Its customers run from touring pros and front-of-house engineers to studio producers and audiophiles paying up to four figures for a pair.
