Concept Learning Stereo USB Headphones with Microphone in Silver [HH00639]

Concept Learning Stereo USB Headphones Description

Concept Learning Stereo USB Headphones in Silver. Specifically designed for educational environments where isolation and voice feedback are required, this headset features noise-reducing earcups that lower ambient noise so volume does not need to be as high; this is recommended by audiologists for hearing safety.

This headset features an in-line volume control for added flexibility. In addition to the in-line volume and mute control, there's a microphone on/off switch. The unidirectional microphone has a flexible gooseneck and built-in wind screen to reduce recording of extraneous sounds.

The USB connection on this headset eliminates the need for a soundcard, making it a plug-and-play device. No additional software or hardware is required to use it. Additionally, it works out of the box with Macintosh or Windows computers.

Knowing this headset may take some rough treatment, the unit has been designed to withstand use by multiple, sometimes not-so-careful students. The fully adjustable headstrap made with rugged ABS plastic and replaceable earcups make this headset perfect for classroom use. The extra-long, 10-foot cord means you don't have to worry about stretching the cord into tight situations.
