Califone 4100 User Manual

USB Headset

Model 4100-USB

1. Recessed wiring resists prying fingers for school safety

2. Fully adjustable headstrap, earcups and headstrap made with
rugged ABS plastic for added durability in high-use settings

3. 10’ straight cord won’t tangle with other wires and is lengthy
enough to reach rear computer ports

4. Backwards-compatible USB 2.0 plug ideal for high speed internet
use, delivers a more balanced sound distribution with “plug and
play” performance (meaning Windows and Mac compatibility)

5. Accessible in-line volume and mute control, mic on/off switch

6. Unidirectional electret mic with flexible gooseneck and built-in
wind screen reduces recording of unintended sounds

7. Permanently attached cord with reinforced connection resists
accidental pull out for classroom safety

8. Noise-reducing earcup lowers ambient noise so volume does not
need to be as high - recommended by the American Speech­Language-Hearing Association for hearing safety

• One year warranty for school use - unlike headsets purchased at
consumer electronics stores whose warranties would be voided if
used in schools

The USB Headset is the first headset designed
specifically for school use with USB connectivity.
Its unidirectional mic and noise-reducing
around-ear earcups are ideal for high speed
internet use for distance learning applications,
tutorials, language learning and situations
requiring isolated vocalized feedback.
