high-polymer diaphragm capable of 10Hz-25kHz frequency, not to mention a 1” oxygen-free copper voice coil designed for improved signal transmission and conductivity, thereby offering a more precise and accurate reproduction of sound.

In addition, the Koss MV1 relies on closed cushions and a tight seal around the ear to help eliminate ambient noise while at the same time maximizing bass and treble clarity. The MV1 also features foldable earcups for convenient storage, a coiled single-entry 8 ft. cord, a 3.5mm plug with a 6.3mm adapter, and an adaptable steel/rubber headband design for even further improved isolation. The Koss MV1 is priced at $179.99 and is considered quite affordable considering its numerous features and high-quality frame.
