Plantronics HW510V Corded Headset Introduction
What To Consider

Poly (Formerly Plantronics) EncorePro HW510V Monaural Corded Headset – Poly 89435-01 or HP 783Q3AA#ABA

When considering call center headsets, the Poly EncorePro HW510V headset part # Poly 89435-01 or HP 783Q3AA#ABA should be one of your top choices. With a full-size ear speaker/ear cushion, you create an excellent barrier that separates background noise from the voice of your caller.

The more accurately you hear, the less time is needed to repeat facts, and information won’t be taken down incorrectly.

How frustrating it is when sales agents take orders and have the wrong address or model numbers entered into the system. Immediately the confidence of the customer is affected when the delivery is delayed or when the box is opened to find the wrong item inside.

From that point on the customer is thinking if they can’t get the first order right, why should I continue to do business with them to only be frustrated again.

The Poly EncorePro 500 Series Is The Headset For Call Center Heroes

In a busy call center, the Poly EncorePro HW510V headset will help your agents hear your callers as clearly as possible. With an extendable and replaceable voice-tube, you will also find your callers hear your agents better, offering optimal voice clarity.

The more your caller and agent can focus on each other with fewer background distractions, the more accurate information will be exchanged, and a more fluid call will result.

With call center headsets, you also want a durable headset that is made to last through 24/7 use and abuse. The Poly HW510V headset has laser-welded construction and is backed by a 2-year warranty to ensure you get the most out of your headset investment.

By replacing the ear cushion on occasion, your contact center agents will feel like their headset is new again with years of anticipated use ahead. By selecting the Poly EncorePro HW510V headset, your agents can keep one ear open to their co-workers or managers.

This is beneficial for agents so they can easily communicate with others when they need to ask questions or keep in contact with coworkers.

With high-quality contact center headsets, agents will want to leave their headsets on during their shift, so finding a comfortable well-fitting headset is crucial. With the HW510V, you have a soft foam cushion and an adjustable headset ensuring a perfect fit for all-day comfort.

To maximize the headset investment in your call center, the Poly HW510V headset needs to be at the top of your list when considering business-grade headsets.

Poly EncorePro HW510V Insider Info:


When installing the Poly EncorePro HW 510V, the first task is to properly fit it to your head.  Position the headband over your head with the ear cushion against your ear.

The opposite side of the headband is called the T-bar, or temple pad.  This should be positioned above your other ear and may require adjusting the headband by sliding it in to make it smaller or out to make it larger.

The end of the voice tube needs to be ¼ of an inch (the width of your finger) away from the corner of your mouth. You can rotate the voice tube up, down and extend 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 HW510V, 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 the shaft that the voice tube slides onto.  The Poly HW510V 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 one ear covered and the other open, the EncorePro monaural 510V keeps you in tune with what’s going on around you and makes it easy to converse with others.

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