Product description

Wireless convertible headset + EHS cable for Siemens phones

Introducing the Plantronics CS540 + APS-11 EHS cable, the ideal bundle for your everyday office communications. The Plantronics CS540 is a best-selling wireless convertible headset designed for desk phones. Meanwhile, the APS-11 EHS cable allows for remote call management using both Plantronics headsets and Siemens telephones. It is an extremely lightweight and practical cable, which connects to your telephone to allow you to answer and end calls with your Plantronics headset when you are away from your phone.

Complete wireless freedom

With the EHS cable, the CS540 headset provides complete wireless freedom to communicate at work. It has a range of up to 100 metres, meaning that there is a great degree of flexibility. Even when you are away from your desk phone, rest assured that you will never miss an important call again. Thanks to remote call management, complete other important tasks at hand while handling your calls.

Outstanding audio quality

For excellent sound quality, this pack has got you covered. DECT technology provides fantastic sound quality and removes interference from Wi-Fi networks. Not to mention, the CS540 also features Plantronics´ brand new CAT-iq technology, which offers advanced wideband audio for high definition conversations. If this wasn´t enough, DSP technology produces a sharp and natural sound. This gives the impression that you are having a face-to-face conversation with the person on the other end of the line. The noise-cancelling microphone removes 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

With this headset, you can register up to 4 headsets to the magnetic charging dock for conference calls. This is a useful feature for telephone meetings involving one external user and various people within the office. Use this feature for training purposes or for when individuals need to listen in to conversations.

2 wearing options

Thanks to its convertible design, choose a wearing style that works best for you. The headset comes with both a headband and an ear hook, which guarantee comfort all day long.

Easy to use and charge

This Plantronics headset comes with a stylish new magnetic dock, which ensures quick and easy charging. Don´t worry if the headset is not positioned correctly, it will still charge properly. It is very straightforward to use and with just one button, control volume levels or activate mute.

An excellent product that works perfectly, no setup required, and the headband is very comfortable. We were able to spend hours on the phone without any problems. Before, I had a cordless phone from a major brand, and my callers complained about unpleasant noise. With this headset, everyone I talk to is delighted to have a clear conversation. I highly recommend this product.
