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 specifically do the Pro4AAT Full Size Headphones have to offer?
The Koss Full Size Pro4AAT Stereophones
Koss Pro4AATs are a new twist on legendary headphones. Getting their inspiration from the Koss Pro4AA, the Pro4AAT feature dynamic elements for an exceptionally wide frequency response. This fresh take on the long-time industry standard features a 2 mm titanium coating on its diaphragms for increased rigidity, minimised mechanical distortion, and exceedingly accurate sound reproduction.
Koss Pro4AATs feature Pneumalite ear cushions with a favourably tight seal which allow you to enjoy improved noise isolation and maximum bass as well as full comfort without inducing aching or sore ears after they have been worn for a while. This is further aided by the adjustable slide bars which ensure a snug fit for more great sound and noise reduction.
The heavy duty, single entry, 8 foot coiled 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. The lightweight design provides for ultra-portability, so you can comfortably carry them around your neck or fit them into your bag for ultimate protection wherever you go and the Pro4AAT standard 3. mm plug comes equipped with a larger, 6.3 mm adapter so you may easily switch back and forth between your listening devices.
This is all backed up by the Koss Stereophones Limited Lifetime Warranty.
