About this model
The Koss Phase/2 is a vintage on-ear stereo headphone from 1974, notable for the onboard controls built directly into the headset. It features an Ambience Expander to widen the stereo field, a Comparator for adjusting stereo imaging, and individual left and right channel volume controls - an unusually hands-on listening experience for the era. The cable terminates in a standard 1/4" jack, making it compatible with amplifiers, receivers, and other full-size audio equipment of the period.
A great opportunity to own a Koss Phase/2 at this price point.
