What To Consider
Plantronics HW520 Corded Headset Introduction

Poly (Formerly Plantronics) EncorePro HW520 Binaural Corded Headset – Poly 89434-01 or HP 783P6AA#ABA

With numerous agents talking on the phone at the same time, call centers typically offer users dual-ear headsets such as the HW520 part # Poly 89434-01 or HP 783P6AA#ABA which serve two purposes.

First, by having both ears covered, the user can hear more clearly and focus better on their calls. This improves call efficiency, by eliminating the need to ask for information to be repeated and agents won’t take down incorrect information when taking orders.

Second, when you cover both ears with a Plantronics binaural headset, you will significantly lower the overall volume of the call center, because users no longer have to talk over each other.

The Poly EncorePro HW520 headset is one of the most popular headsets when it comes to call centers and offices where employees need to focus on callers and not be distracted by background noise. Built with laser-welded construction, the HW520 is made to last and be comfortable for 8+ hour shifts.


Poly EncorePro HW500 Series Wired Headset

The Headset For Call Center Heroes

In the past, Plantronics binaural headsets had cables that split under your chin, feeding a cable to each of the binaural ear pieces. As technology has advanced, you now benefit from single cable design, where the second speaker is cleverly reached using a flat ribbon cable hidden in the headband that goes over your head.

Even though the headset has two speakers, the Poly EncorePro HW520 headset is engineered to provide the same sound in each speaker. This is typical of most business-grade headsets, even though they are mistakenly referred to as stereo headsets.

True stereo, or hi-fi headsets, will have separate channels to each speaker allowing different sounds to be heard while listening to music or movies. If you need a dependable, great sounding, cost effective Plantronics binaural headset solution, the HW520 should be on your short list of headset options.

Poly EncorePro HW520 Headset Insider Info:


When installing the Poly EncorePro HW520, the first task is to properly fit it to your head. Position the headband over your head, with the ear cushions against your ears. It may require adjusting the headband by sliding it in to make it smaller or out to make it larger so both ears are covered and comfortable.

The microphone needs to be ¼ of an inch (the width of your finger) away from the corner of your mouth. You can rotate the mic boom up and down for perfect positioning.

At the end of the headset cable you will find a connection called the Quick Disconnect. You will have a matching connection in which to plug the cable, located on your amplifier or cable, depending on compatibility and your application. Make a test call to ensure the unit is working properly.

Also, many users disregard using the clothing clip, when in actuality it plays an important role in making the headset appear very light weight. By clipping it on or near your shirt collar, the weight of the lower portion of the cord stops at the clothing clip. You will never feel pulling on the headset or the need to re-position it as you reach and stretch the lower cord.


When storing , it’s best to place the headset over a hook so it’s not just setting on your desk, and this also keeps the cord hanging freely.

If left on your desk, the cleaning crew can easily bump it and knock it to the floor, where the cord can find its way into the vacuum. You also want to let the cord hang free and avoid tightly wrapping it, which over time will damage the internal wires.

We developed a headset hanger to affix to your monitor in an effort to keep your headset safe and out of harms way. To view click HDI Headset Hanger.


When cleaning your Poly HW520 headset, always use non-alcohol chemicals or wipes. Using alcohol-based products over time will break down the cords making them very stiff and clumsy to use.

You will want to wipe all plastic components and cables, but avoid saturating any openings where electronic components are in close proximity. This will include the small holes in the speaker casing and at the end of the mic boom where the microphone is located.

The Poly HW520 comes with foam cushions, which can be replaced as needed. When cleaning, also avoid sticking anything into the end of the Quick-Disconnect connection where the four metal contacts are located. This connection is made to last, and more damage than good will come if you try to clean it.


This headset is made for a business professional looking for the best possible quality in a corded headset. With a binaural headset covering both ears, the Poly HW520 keeps you focused on your caller.

The noise-canceling microphone will cut down on background noise, making for a great headset in louder environments.

  10. Gwen

    Excellent Customer Service. I have tried several headsets for a call center and there was a problem with all of them. It is a small room, so we were getting background noise and problems with the caller hearing us. I have searched all over and the reason I purchased these was “Wayne.” I searched and found this company and then called and he answered the phone, I explained the situation and he directed me to what I needed to purchase. I only purchased one set to make sure they were going to work. I called him a couple of times with questions and he was always great to answer and guide me with all of my questions. I placed an order with “Wayne” yesterday to replace all of our headsets. The product is great but the customer service “Wayne” was the best. Thanks again for all of your help.

    We are using this headset in an office with multiple cubicles, it is working well to help with outside distractions while on a call.

  16. Lee McGrath

    Dear Sir/Madam:
    Your company is to be applauded for including in your order process a quality-check by an experienced customer service representative. I appreciate greatly that one of your representatives reviewed my order and called me. She politely explored with me the need for a cord to connect the headset to my phone. By doing so, you made a small incremental sale. More importantly, you made a huge difference for me. I would have been very frustrated to receive the headset and not been able to use it immediately.

    Thank you.

  17. Pat
