Wireless headsets are slightly more expensive but the benefit is the freedom to roam your office and accomplishing other tasks while continuing your calls. Most importantly when purchasing headsets for use in your office, wearing style and functionality are key. As for wearing style, you will want to decide between over-the-ear (tends to be lighter weight and lower profile) and over-the-head (tends to be more durable, longer battery life and best audio quality). As for functionality, will you only use it with your desk phone, or would you prefer a unit that connects to multiple devices, such as your desk phone, PC and mobile phone. Another key consideration with wireless headsets is the ability to add a cable or lifter which provides you remote call alerts, remote answer/hangup capabilities, and simplifying how you take calls.
