MINIMIZE UNWANTED NOISE: With a unidirectional noise-cancelling microphone, this mic only picks up sound from a specific side or direction of the microphone. This helps minimize all ambient noise while speaking or recording. Ideal for K12 classroom learning, conference and Skype calls and webinars. ONE SIZE FITS ALL: With an adjustable headband and leatherette ear pads, these headphones can be adjusted to fit most head sizes and with a flexible microphone boom arm, you can choose what angle the mic sits at. EASY TO USE: Simply plug in and play, no installation needed. Connect 3.5mm plug directly to your desktop computer, laptop, tablet, smartphone, MP3 player or gaming system.
