"Product Description 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 SB45 Full Size Communication Headsets have to offer? The Koss SB45 Full Size Communication Headset Koss SB45 communication headsets deliver a full range of sound that enables you to not only hear clearly, but also speak clearly. Featuring Koss’ Clear Voice Technology (CVT), the SB45 noise cancelling microphone eliminates excessive background noise. This enables PC voice applications, such as speech recognition, much easier to use. The comfortable design of the Koss SB45 will allow you to comfortably wear these headsets over an extended period. The large closed, soft leatherette ear cup maximise isolation so you can focus on the task or conversation at hand. The straight, single-entry 8 foot cord will allow you extensive freedom of movement to ensure that you can position the headphones for optimum listening, making them ideal for workouts, gaming and more and when not in use these computer headsets easily fold up for compact storage or transportation. All this is backed up by the Koss Stereophones Limited Lifetime Warranty. "
