Digital USB headset offers laser-tuned drivers to minimize distortion, support for super wide-band audio, and a pure digital USB connection for clear audio in stereo. Super wideband audio allows a larger range of frequencies so voices sound more natural. H530 also provides support for voice and video calls made with Logitech Vid, Skype 4.0 for Windows and Skype 2.8 for Mac or later. Optimize EQ settings for Internet calls, music, or PC gaming using the convenient control switch on the headset. On-ear controls also adjust the volume and mute microphone. Headset also features a noise-canceling microphone, flexible rotating boom, padded foam headband, cushioned ear cups and 8' cable. Headset plugs into a USB port and works with Windows and Mac OS.
