The PortaPro stereo headphones from Koss provide high-quality audio in a vintage design. Unchanged since 1984, the PortaPro offers a unique and recognizable look with performance to match. The headphones use rigid Mylar drivers to minimize distortion and provide accurate reproduction, while NdFeB magnet structures deliver strong volume levels. Oxygen-free copper voice coils improve signal transmission for clean, clear sound.
The adjustable headband conforms to virtually any head size, while the foam earpads provide comfort and also let you maintain awareness of your surroundings. The cable provides plenty of slack and has a standard 3.5mm mini plug for connecting to MP3 players, CD players, and much more.
