Amazon.com Product Description
Koss's KTX-Pro portable headphones affordably deliver intimate stereo sound with a frequency response rated at 15 to 25,000 Hz. Their titanium-layered diaphragm fosters accurate sound reproduction while open-ear, foam-layered earpieces offer less colored sound than a closed-ear design. This format, while ideal for home use, make these headphones less than optimal performers when used portably, as outside sounds tend to creep in more easily (and your music can be heard by others!).
These lightweight stereophones feature an adjustable headband with sling for a comfortable, secure fit. An inline volume control on the KTX-Pro simplifies level adjustment. Koss also includes a straight dual-entry 5-foot cord along with 0.125-inch and 0.25-inch stereo plugs for versatile portable or home use.
Koss's outstanding lifetime parts and labor warranty backs the KTX-Pro.
