Manufacturer: Logitech. The adjustable, sliding headband and pivoting ear pads provide a lightweight, comfortable behind-the-head fit that adjusts to the shape of your head and reduces pressure that can cause fatigue. The headset plugs into any USB port on your Mac or PC for a clear, digital connection. With super wideband audio (Super wideband audio supported in Logitech Vid, Skype 4.0 for Windows or later and Skype 2.8 for Mac or later) you’ll enjoy conversations so clear it almost sounds like you’re in the same room as the people you call and the headset is ready for music, movies and games too. You can position the microphone right where you want it and rotate it out of the way when you’re not using it and with the noise-canceling feature you won’t have to compete with background noise to be heard. The in-line audio controls allow you to instantly adjust the volume and mute the microphone.
