You can read through our product listing, or learn more about the Plantronics CS540 wireless headset by watching our review video that includes a microphone sound quality test. Either way, you'll find the CS540 to be a headset well worth your time to consider.

Here’s why people keep ordering the Poly CS540 DECT wireless headset:

Lightweight Design

The Poly CS540, also known as the C054, or C054A Plantronics headset, weighs only 0.64 ounces (0.04 pounds). Putting this into perspective, that’s the same approximate weight as:

• A tea bag filled with loose leaf tea
• A slice of bread
• Three sheets of paper

The CS540 is light, which means it’s a headset you can wear for long periods of time without feeling the discomfort of a heavy headset.

Wearing options

Choice is yours. We all like choices, and the Poly CS540 gives you three of them. Rather than being stuck to one wearing style you have the choice between:

1. 1. Over the ear- ear loops and ear tips - included
   2. Over the head headband covering one ear - included
   3. Lightweight behind the neck band - optional

Prefer an earpiece? When you order the Poly CS540 you get ear loops, and ear gels for a snug, secure on-ear wearing experience allowing you to find the loop and ear tips size that’s right for you. This is perfect for those looking for a lightweight, discreet, on-ear headset wearing style.

Over the head more your style? The CS540 also comes with the monaural, single ear headband. When matched with the lightweight CS540 headset top, it gives you a lightweight headband wearing option.

Neckband. If you’d like a uniquely different and comfortable wearing style, you can consider the optional behind the neck band. Nothing to go over the ear or over the head because the band wraps around the neck for a lightweight alternative wearing style.

Easier Headset Deployments. Having these choices help to make deploying headsets easier. Distribute the headsets, and have the staff decide which wearing style suits them best. And there’s always the option of the neck band too. Choices are nice!

Connectivity

The Poly CS540 DECT wireless headset is designed for use with desk phones and remains a leading wireless headset option for office phones across brands like Poly, Cisco, Avaya, and more. If you're curious about the differences between similar models, be sure to explore more about C054A Poly headsets. With a 98% connectivity rate, it works flawlessly just like it’s done since 2011.

The CS540 comes with a Telephone Interface Cable that plugs into the CS540 headset base, and into the desk phone. This cable, along with the AC Power adapter, and a charged headset battery is all that’s needed to get up and running. Simple to connect, simple to use and a simple, sensible choice.

Answering Calls Remotely. If you want the ability to answer and end calls when away from the desk, then you’ll need one of two devices for use with the CS540:

1. Handset Lifter (model HL10 - optional). The HL10 is a popular choice for those looking to answer and end calls when not at the desk. This is an adaptable device that provides remote call control.

2. Electronic Hookswitch Cable, a.k.a., EHS Cable (phone make/model specific - optional) This is an alternative to the HL10 handset lifter, and represents the next generation of remote answering devices. Simple to install, and highly efficient.

The APP-51 shown below is for use with certain Poly desk phones. Other phone makes/models would require a different cable because these cables are phone make/model specific.

How they work. A Handset Lifter, and EHS Cable will provide you with a quiet beep tone in the headset earpiece when receiving an incoming call. Once notified, simply press the call control button on the side of the earpiece to accept the call, and press it a second time to end it. This can be done up to the available wireless range. More on wireless range below.

How they connect. The HL10 fastens to the surface of your phone via double sided tape, just beneath the handset receiver. It’s called a handset lifter appropriately because it physically lifts the handset to allow taking an incoming call.  By contrast, the EHS Cable doesn’t require a physical device like the lifter. Instead, it plugs into the phone and headset base and provides hookswitch control electronically, rather than electro mechanically. Both work well, but the EHS cable tends to be more reliable long term, and there’s no real price difference.

Need Computer Connectivity?

Switching to Softphones? If you’re planning to switch over to Softphones, and away from using desk phones, you may be concerned about the CS540 being a desk phone only headset. If so, then here’s some information you’ll want to know about.

The Poly CS540 has the ability to be used with a computer with an affordable, optional computer connection cable. With this cable, the CS540 extends its usefulness, transforming from just a desk phone headset to one of the best wireless headsets suitable for office phones and softphone transitions. You can also explore the C054A Plantronics wireless headset for comparison and you avoid the added expense and inconvenience of buying new headsets? Here’s all you need:

Rather than plugging the CS540 into the desk phone, plug it into the D315 instead, and and you'll have a versatile wireless headset designed for office phone systems that can also connect to desktop or laptop computers. The cost of headsets can add up quickly, especially if you’re outfitting a team. The Discover D315 allows you to extend the use of your headsets, and helps you to avoid the cost of new headsets. 

Sound Quality

The Poly CS540 comes with a professional-grade, noise-canceling microphone, which is similar in quality to the C054A Plantronics model. Its sound quality has stood the test of time, and remains one of its most popular features.

So if you’re looking for a headset that keeps you sounding professional, and one that helps to dampen down the noise going on around you, then the  CS540 is a worthwhile headset to consider.
