Product information

For effortless and efficient communication at work without distractions

The Plantronics CS520 is a binaural headset designed for desk phones, it is a perfect choice for people who spend much of the day on the phone and want to focus all their concentration on their telephone calls, without distractions from the office. 

Complete wireless freedom

This wireless model with lifter gives complete wireless freedom to communicate at work. With a range of 100m and a talk time of up to 13 hours mobility is guaranteed for the user.

Handset lifter

With the optional extra of the handset lifter, you can answer calls even if you are away from your desk. You'll hear a short beep when a call comes in, and you can answer by simply pressing a button on the headset. 

Outstanding audio quality

This Plantronics 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 sharp and natural sound.

The noise-cancelling microphone blocks out background noise meaning that the person you are talking to will only hear what's important - you.

Register up to 4 headsets for conference calls

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.

Easy to use and charge

The CS520 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. It is very straightforward to use, with just one button you can control the volume levels or activate mute.
