Plantronics HW520V Corded Headset Introduction
What To Consider

Poly (Formerly Plantronics) EncorePro HW520V Binaural Corded Headset – Poly 89436-01 or HP 783P8AA#ABA

When considering call center headsets, the Poly EncorePro HW520V headset part # Poly 89436-01 or HP 783P8AA#ABA should be one of your top choices.

With numerous agents talking on the phone at the same time, call centers typically offer users dual-ear headsets 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, because you don’t 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.

Poly EncorePro HW520V Headset

The Poly EncorePro HW520V 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 HW520V is made to last and be comfortable for 8+ hour shifts.

With call center headsets, you also want a durable headset that is made to last through 24/7 use and abuse. The Poly HW520V headset has laser-welded construction and is backed by a 2-year warranty to ensure you get the most out of your headset investment.

Poly EncorePro HW520V Insider Info:


When installing the Poly Encore 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 when using the binaural HW520V.  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, 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 HW520V 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 HW520V keeps you focused on your caller.

The extendable voice tube will ensure your callers will hear your voice as crisp and clear as possible.

  1. Shawn

    Can’t say anything negative. The headset works. Purchased about 10-15 for some users here and none of them came back to me so I guess they work well enough.

    What I can say is I ordered the wrong cable and the ordering team fixed it correctly before they shipped it. Customer service also has answered quickly. Kudos to those 2 areas.
