Koss PortaPro Stereo Headphones

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.
