The new Howard Leight SmartFit(tm) reusable earplug uses Conforming Material Technology(tm) to adapt its original form to the unique shape of the individual's ear for exceptional comfort and a custom-like fit with an off-the-shelf product. Heat-activated materials sense the contours of the user's ear canal and adjust their shape accordingly. Howard Leight Industries, Bacou-Dalloz, Inc., San Diego, CA.
