implicity is the best way to describe the Plantronics HW540 corded headset. Classed as a convertible headset, three different wearing options are included, ensuring you find the perfect fit. You can easily change from over-the-head, over-the-ear, or behind-the-neck styles to find what is most comfortable for your all-day wearing comfort. A flexible noise-canceling microphone allows for perfect positioning, so your callers hear you with less background noise and distractions. If you choose over-the-ear, the ear hook is bendable and flexible, conforming to your ear for a more secure fit. For over-the-head users, the headband is adjustable, and the temple pad (on the opposite side from the speaker) is soft and pliable. With any wearing option, a soft ear cushion rests against your ear, covering the speaker, which provides the latest in audio sound quality. A clothing clip is included, which helps the headset stay perfectly positioned, as the clip becomes the point where cord pulls are confined, rather than pulling on your headset.
