Selling Logitech H540 wired USB computer headset. The headset features a noise cancelling mic and on ear controls. A good headset for music or audio calls. The headset is brand new in a box. It was purchased to use with an IP phone, and I went with another product. Since the box was opened, it cannot be returned.
H540 USB Computer Headset features plug-and-play connectivity so you can instantly enjoy music, movies, and calls in rich, digital stereo sound. On-ear controls and mute indicator light make it easy to see when the mic is muted.
