Stylish and durable, this mono headset delivers comfort day after day to make every call more productive. Acoustic echo cancellation, a noise-cancelling mic, and digital signal processing (DSP) block out unwanted noise for clear conversations with great sound quality. Leatherette ear pad, plus padded headband with metal reinforcement, provides strength and flexibility with a fit that's just right. Plug-and-play technology lets you simply connect it to a PC or Mac through its USB cable with no additional software required for immediate use.
