Introducing a totally new concept in stereophones.
The new Koss HV/X high velocity stereophone represents a remarkable breakthrough in hear-thru stereophone design and performance. For the first time, Koss engineers have been able to create a lightweight, hear-thru stereophone that combines the transparency of high velocity phones with the superior bass performance of closed -type phones. The result is a breathtaking musical experience.
CONTOURED VARIABLE-DENSITY EARCUSHIONS
While most lightweight, hear-thru stereophones have earcushions that fit against the ear, the new Koss HV/X features a unique, contoured, vari able -density cushion that fits around the ear. Not only does this unique ear-cushion design create a far more comfortable stereophone but it has also allowed Koss engineers to create a dramatically better element design as well.
These new variable -density earcushions are made up of a very porous material that is acoustically transparent at the perimeter of the ear-cushion yet com pressed toward the center region. This varies the pattern of acoustic resistance over portions of the earcush ions creating the proper seal for specific bass frequencies while allowing the flow of middle and high frequencies at the perimeter of the earcushions.
LIGHTWEIGHT ELEMENT
The uniqueness of the new variable -density ear-cushions made it possible for Koss engineers to design a lightweight element that reproduces a Sound of Koss you have to hear to believe. Incredibly, even though the overall weight of the element was reduced, Koss engineers were able to develop a magnet with enough magnetic density to drive an extra large diaphragm.
With a response range of 15 to 35,000 Hz, the new Koss HV/X will drive you into ecstasy and our competitors nuts.
HEARING IS BELIEVING.
Slip into the new Koss HV/X or HV/XLC with volume/balance controls at your audio dealer soon.
You'll like the best of both worlds: the open, airy, up front sound of hear-thru stereophones and the deep, rich bass performance of closed -type stereophones.
And while you're with your audio dealer, listen to our full line of Koss stereophones and CM loudspeakers. There's no sound quite like the Sound of Koss.
