Notable Features:

The facility is primarily functional, geared towards audio innovation and efficient operations. While not a public architectural landmark, it houses specialized acoustic testing labs and product development workshops crucial for maintaining 'The Sound of Koss'.

Employees often share a long tenure, contributing to a focused atmosphere centered on quality and the brand's legacy.

HQ Significance:

The Milwaukee headquarters is historically significant as the birthplace of the world's first commercial stereophones.
