Product description

Ultra-lightweight Wireless desk-phone headset

The Plantronics CS540 Refurb Headset is a lightweight convertible wireless headset which comes with a headband, it's so light you'll hardly feel it's there.

One-touch capabilities

With just one button you can control the volume levels or activate mute and its noise-cancelling microphone to block out background noise which means that the person you are talking to will only hear what's important - you.

Superior sound and voice quality

The Plantronics CS540 wireless headset uses DECT technology, which gives it fantastic sound quality and eliminates interference from Wi-Fi networks. It also features Plantronics' brand new CAT-iq technology, offering advanced wideband audio for high definition conversations, and Digital Signal Processing (DSP) for a sharper and more natural sound.

Register Multiple headsets

One of the brand new features of this range is that the CS540 allows you to register up to 4 headsets to its dock for conference calls between each other. This is a useful function for telephone meetings with one external user and various people within the office, for training or for when people need to listen in on conversations.

The CS540 refurb comes with a stylish new magnetic dock, which you can put your headset on to charge up quickly and easily, without having to worry if it is properly positioned.
