The Plantronics H171 is a convertible headset with Plantronics superior voice tube microphone technology. The H171 offers a choice of wearing styles designed to suit individual preferences. Included with each H171 is a double temple pad headband, which distributes the weight of the headset onto your temples; totally eliminating any pressure around or on the ear. For individuals who prefer wearing their headset over the ear, rather than over their head, the H171 provides a flexible ear loop designed to conform to the shape of your ear. Included is a soft foam ear cushion, which further enhances comfort ability for the over-the-ear wearer. In addition to the over the head and the over the ear styles, you may also choose an optional neckband version of the H171. With three wearing styles to choose from the H171 headset guarantees a comfortable fit for every individual.
