For everyday listening

These headphones are made ??with regard to everyday use, because shells are made ??of aluminum and cushions made ??of memory foam wrapped in convenient and comfortable leather. The new integrated metal headphone design makes the Pro / 4S extremely robust headphones in areas where other headsets often fail .

Koss Pro / 4S have a detachable cable (3.5 mm jack), which can be connected to both the left and the right shells for optimum adaptation. Free connector becomes output, which you can use to connect additional handsets and one sound source can be used for multiple listeners.

unique design

Finally, it is necessary to mention the special D-profile ear cushions around the shape of your ear. It sounds like a marketing draw, but in the shape of a "D" provides much greater comfort than the classic round shape. With this structure fit almost any headphones. In combination with a cushioned headband is achieved maximum comfort even during extended wear. Pleased overall size headphones that do not reach the size as the standard studio headphones.
