Designed for mobile devices, the Andrea Communications EDU-455M headset is ideal for use in educational settings, as a computer headset, or just for listening to your favorite tunes. The EDU-455M offers unparalled speech and sound clarity and includes a convenient in-line volume control. The exclusive noise-canceling microphone with internal windscreens, which minimize breath popping, has been awarded the coveted "6 Dragon" rating for speech accuracy by Nuance. The heavy duty rigid boom and swivel allow for perfect microphone placement. Extra-thick leatherette ear cushions block out surrounding noise. An adjustable dual headband ensures a comfortable fit even on smaller heads.h
