OH-1V 3.5mm mono plug
The professional-grade Odyssey is designed for heavy-duty use in K-12 and college classrooms and (multimedia) computer labs. It is Windows and MAC compatible and can function in stereo or mono with a simple cord change.
The Odyssey is remarkably comfortable because of its extra deep earcup cavities and is very quiet with ambient noise reducing earcups, which help keep students on task while reducing the need to increase the volume. Beneath its rugged headband is a flexible comfort sling, which contours to the user's head for better weight distribution and balance, also contributing to a more comfortable experience. Volume control is on the back of the right earcup.
Its replaceable 6' cord withstands 250,000 flexes, and with a cord change (from stereo to mono, or mono to stereo), enables the same headphone to operate instead in mono or stereo mode for added flexibility. This also allows minor repairs to be made without purchasing a new headphone body. Both cords have a 3.5mm plug. The connection point with the earcup is recessed to prevent accidental disengagement of the cord.
