The lightest, most comfortable over-the-ear headset, the TriStar headset, offers premium sound quality and is the first to combine light weight and small size with a unique design to provide optimum over-the-ear fit. The TriStar NC headset is also available with the added benefit of a noise-cancelling microphone, eliminating background noise by up to 75%. With its simple design, replacing the voice tube or earpiece is quick, cost-effective, and takes only seconds. TriStar headsets are ideal for executives, call centers, and help desks, as well as technical helplines, credit control, sales offices, and telemarketing.
