Acquired in mid 2008 from the founder of Ridgeline, Inc. Ridgeline started in his garage outside of Phoenix, AZ in 1992. An avid shooter and hunter, he had recognized the need for a high quality, comfortable and reliable hearing protectionr and sound amplification. Working with a world-class engineer from Motorola they created the first, and to this day, only compression system to limit high decibel sounds while amplifying low decibel sounds. The market has enthusiastically responded to this innovation. By 2008 after many product and business improvements the founder decided it was time to enjoy the fruits of his labor and retire. Altus Brands reached agreement to acquire Ridgeline, which at that time had been relocated to Westcliffe, CO. The company has since been relocated to the Altus Brands home office in Traverse City, MI where we continue to manufacture and distribute the world’s best electronic earmuffs.
