The Plantronics SupraPlus wireless headset for Avaya system phones is specifically designed to work with the Avaya system. The headset is built for heavy use and ideal for people taking and making regular, lengthy calls. One Ear Piece or Two? Available with one ear piece or two, this headband style headset offers two options to suit any office environment. With one ear piece you can concentrate on the call whilst still being able to easily confer with surrounding colleagues. The two ear piece version is better suited to nosier offices where you may sometimes have difficulty hearing what the caller is saying, two ear pieces allow you to fully concentrate on whats being said without any distractions. Being lightweight, both headsets are suitable for all day continuous use. Noise Cancelling By having a noise cancelling microphone, a large percentage of unwanted office background noise is cancelled out, resulting in a much clearer conversation. In addition to this, its QuickPairÔ feature allows shift workers who may own their own headset but share a base unit, quickly and easily register the headset at the start of their shift at the touch of a button. Talk Time Thanks to its large talk time of 9 hours and a standby of 50 hours, it will last the whole day without the need to recharge, however it also benefits from a fast recharge of 3 hours, to reach full capacity. With the SupraPlus wireless headset, you can stay mobile all day with an array of features that are directly accessible from the earpiece, for example, volume and mute control. With its in-built hook switch, calls can even be answered and ended away from your desk, giving you more freedom in your workplace.
