If it ain't broke, don't fix it. That has to be one of our favorite expressions here at CNET, and the hearing professionals who head up Westone clearly abide by it. In 2006, we got our hands on the company's only two pairs of consumer earphones--the UM1 and the --both of which received high marks for their good looks, comfortable fit, and excellent sound quality. Rather than toy with two winning products, the company has added a third headphone to the lineup, the ultrahigh-end Westone 3 True Fit Earphones ($399). These super sweet-sounding headphones are pricey and a bit chunky for our liking, but their stellar audio performance more than makes up for any misgivings. .
