The Koss PortaPro collapsible stereophone combines high-quality sound reproduction with a unique design for the ultimate in convenience and comfort. These over-the-head headphones have a dynamic element design for deep bass performance and a frequency response of 15 to 25,000 Hz to ensure the music comes through clear and bright. Also designed for comfort, these headphones have two adjustable temporal-comfort zone pads to shift the pressure and perfectly balance the ear plates on your ear. The open-earphone ear plates are multipivoting and, together with the adjustable headband, allow for maximum comfort.
The PortaPros are collapsible and come with a carrying case, so it's still easy to take them with you even when you're not wearing them. A 0.25-inch adapter is included to ensure they will fit with any system.
Koss offers a lifetime warranty on its PortaPro stereophones.
