About Us

GLK Communications was formed in 1995 by Greg Cornehls, one of the founding fathers of the stereo headset industry. GLK is a US company with offices and manufacturing facilities located in New Berlin, WI.


During his successful career at Koss Corp, Greg Cornehls, developed global markets for the stereophone industry. In later years, Greg and his son Keith, of Sterling Stereophones pioneered the world’s first line of stereophones using titanium elements. Today, GLK Communications is fully owned and operated by Greg’s son Keith. He continues the tradition and customer oriented business philosophy set forth by his father.


GLK Communications continues the decades old legacy of providing high quality headsets, at throw away prices, for the Drive-Thru and 2-way radio industry under the trade name of, Replacement Headsets.  In addition, in 2007 we introduced two new products:

  • Klear Order System  State-of-the-art technology without the state-of-the-art price tag. The Klear Order Drive-Thru System is the most dependable, easy-to-use and cost-effective drive-thru ordering system on the market. Klear Order System is powered by audio electronics leader Kenwood Communications, and is simple to install and service by the end user. No maintenance contracts, operates with or without headsets and equipment that is so tough that it meets US Military specification standards.
