The Original Stereophone For some, music is a nice distraction. A thing to tap your toes to. For us, music isn’t a thing; it’s a place we go. We are the true believers. Koss has been bringing people closer to the music they love for more than 50 years. The first Stereophone (SP/3) in the world was created by John C. Koss and Martin Lange in 1958 and since then, Koss’ innovative products have gone from strength to strength with a range now including Full Size Stereophones, On-Ear Stereophones, In-Ear Stereophones, Ear-Clip Stereophones, Wireless Stereophones and Communication Headsets. Now, more than 50 years later….Koss’ creation has become a $2 billion industry, worldwide. Three principles serve as the foundation for the company’s success: The sound of Koss; focus on fit and breakthrough customer service. What do these principles mean? The sound of Koss: Musician, John C. Koss created “the sound of Koss” in 1958 and we have stayed true to it to this every day. The sound of Koss brings music back to life. Koss engineers are rigorous in their pursuit of the absolute best sound but it is the human listening experience that sets Koss apart. Focus on fit: We are obsessed with creating the absolute perfect fit – without it; we can’t get the perfect sound. We strive to create products that offer custom settings for every music lover. Our products couple to the ear – it’s just you and your music. Breakthrough customer service: Koss was the first to offer Limited Lifetime Warranty in 1989. Our domestic customer support staff is ready to help any listener with any issue. The Koss US factory and warehouse is based in Milwaukee Wisconsin – logistically, Koss has created an onsite inventory system that makes “out-of-stocks” virtually impossible. With that in mind, what do the Koss CS100 Communication Headsets have to offer?
