Califone DS-4V-CALIFONE Dynamic Headset, with Microphone

This professional-grade headset is designed for heavy-duty use in K-12 and college classrooms and labs. Discovery headsets are ideal for reading, science, math and language learning uses and are compatible with CD/DVD players, TVs, tape players, and most computers. Its built-in noise cancelling dynamic microphone is designed for use with voice recognition programs. Added comfort by extra deep (noise cancelling) earcup cavities with a convenient volume control located on the right. The flexible comfort sling contours to the user’s head for better weight distribution and balance. The replaceable 6’ cord withstands 250,000 flexes, and with a cord change, enables the same headset to operate in either stereo or mono modes for added flexibility. This also allows minor repairs to be made without purchasing a new headset body. Replaceable, easy-toclean vinyl ear cushions are hypo-allergenic, no latex.
