Product Details

The CS540 has been a fixture in professional offices for years, and it is easy to see why. It pairs reliable DECT wireless with a convertible design that adapts to your preference: the stability of over-the-head, the discretion of over-the-ear, or the flexibility of behind-the-neck, all in one box.

Made for desk phone use, it delivers professional audio in your choice of narrowband or wideband. Narrowband stretches talk time; wideband gives clearer, more natural voice. DECT keeps the audio interference-free and shrugs off Wi-Fi congestion, so calls stay consistent from one to the next.

The SoundGuard acoustic limiting is a welcome touch for anyone who lives on the phone. It protects your hearing by capping levels at 118 dBA and smoothing sudden audio spikes. Together with the noise-canceling mic filtering out office noise, the CS540 makes for a comfortable, productive day of calls.

Key Features

Three Wearing Styles

Pick from over-the-ear, over-the-head, or behind-the-neck. The convertible parts let you settle on the fit that stays comfortable through a full day.

Noise-Canceling Mic

The noise-canceling mic cuts down background interruptions, keeping call audio clear and easing listener fatigue for you and the person on the line.

SoundGuard Protection

SoundGuard acoustic limiting holds sound below 118 dBA and guards against sudden loud noises and audio spikes, protecting your hearing across hours of calls.

Adaptive Power System

Near the base, the headset lowers power on its own to balance range and talk time. Pick narrowband for longer battery or wideband for clearer conversations.

Great product. I needed something that cuts out background noise from traffic when walking and kids at home. This headset does exactly that. Using it on its own or with noise-canceling software cuts out literally all background noise. Talk time is at least 6 hours on a single charge and takes about 30 minutes to recharge.

This is an amazing headset. Great quality. Great noise reduction. Good for making business calls and knowing you have a quality headset for it. Soft on the ears and fits well. Good range to walk around the house where I used it. Very clear sound.

Love this headset. I've only had it a little over a year, but I'm super happy with it. It's comfortable on my ears, easy to use, and professional. I never have a problem communicating with clients on the other end. It holds a charge for as long as I need it all day. Highly recommend.

I have made two horrible decisions about who to marry, but my twice choosing Plantronics for the most important part of my business, phone calls, was spot on. The CS540 works great, even better than I assumed. Product is durable and easy to use. Most important: the volume level adjusts appropriately to suit my hearing.

- FunDirector

To install the system was easy and fast. Using the headset has been a game changer for my neck. The pain is gone. I'm able to use the computer and talk with people with no issues. The sound is great and clear.

- Kristine Garcia

I got this unit due to price point and name brand. Was pleasantly surprised by its quality and the ease in which it hooked up to our phones. I am getting several more and the user is deliriously happy with it. Current user was amazed that she could continue on call at a 50 foot distance from her desk.
