Poly EncorePro HW540D Convertible Digital Headset (6-Pin QD, DA90)
The Plantronics EncorePro HW540D wears three ways
Issue one headset model to forty agents and you'll hear about it: someone finds the headband too tight, someone won't wear anything over their hair, someone wants it off their head entirely. The Plantronics EncorePro HW540D Digital Series headset settles all of it with one part number — it converts between three wearing styles, so each agent sets up the same headset the way they like it.
It's the convertible model in Poly's EncorePro 500 Digital line — over-the-head, over-the-ear, or behind-the-neck, all in the box — with the same DA90-managed digital system and contact-center durability as the rest of the family.
Three wearing styles, one headset
The EncorePro HW540D is a 3-in-1 convertible: the same headset wears over the head, over the ear, or behind the neck, using the parts included in the box. An agent picks the style that's comfortable — and can switch any day they want to.
- Over-the-head — an adjustable headband with a soft temple pad on the non-speaker side
- Over-the-ear — a bendable ear hook that conforms to your ear for a secure fit
- Behind-the-neck — a neckband for agents who want nothing over the top of the head
In every style, the same soft cushion rests over the speaker, so the audio and the microphone are identical no matter how it's worn. For a team, that's the quiet win: one SKU covers the headband person, the earhook person, and the behind-the-neck person — so procurement doesn't have to survey preferences or stock three models, and you stop eating returns when someone's issued the wrong style. An agent's preference can even change without a new order.
The EncorePro HW540D needs the DA90
Like every Digital-series EncorePro, the HW540D uses a 6-pin Quick Disconnect and works only with Poly's DA90 USB audio processor (or a 6-pin MDA526). It is not compatible with standard 4-pin amplifiers or cords — SoundGuard DIGITAL hearing protection and Plantronics Manager Pro management run through the DA90.
Convertible, or a single-style EncorePro?
If you've chosen the Digital series, the convertible only earns its place when fit preferences actually vary.
All three wearing styles in one headset. The pick when fit preferences vary across a team, or you want one part number to cover everyone.
One style each — over-the-head (HW510D) or over-the-ear (HW530D), at a lower price. The pick when everyone's settled on the same way to wear it.
The EncorePro build and the digital system
However it's worn, the HW540D keeps the EncorePro fundamentals: laser-welded construction and metal joints for years of heavy use, a noise-canceling boom with visual and tactile positioning guides so every agent sounds clear, and wideband audio. Through the DA90 it adds SoundGuard DIGITAL hearing protection and fleet management. One naming note: the "digital" here is hearing protection, not active noise cancellation — there's a noise-canceling mic for your caller, but no electronic cancellation of the room for you.
The EncorePro HW540D is the one you buy when you don't want to guess how your agents like to wear a headset — you hand them a single part number that does it all three ways, built to last and managed through the DA90 like the rest of the Digital series. Set the style, plug into the DA90, and every agent gets their own fit from the same box, with HeadsetPlus's lifetime support behind it.

Software. Connected through the DA90, the EncorePro HW540D works with PC softphones — Microsoft Teams, Zoom, and others — and, with Plantronics Manager Pro, gives IT fleet-wide monitoring, configuration, and asset tracking. The digital hearing-protection processing runs in the DA90.
Hardware. The EncorePro HW540D requires the Poly DA90 USB audio processor (or a 6-pin MDA526). Its 6-pin Quick Disconnect won't work with standard 4-pin Poly amplifiers or cords. If you don't have a DA90, the standard convertible EncorePro HW540 is the right headset.
Platforms. The EncorePro HW540D is built for IT-managed contact centers where agents' fit preferences vary — customer care, help desks, and telesales that want one headset to suit everyone.
FAQ
Frequently Asked Questions
The EncorePro HW540D is a 3-in-1 convertible with three wearing styles included: over-the-head (adjustable headband), over-the-ear (bendable ear hook), and behind-the-neck (neckband). An agent can wear it whichever way is most comfortable and switch styles whenever they like.
Yes. The EncorePro HW540D uses a 6-pin Quick Disconnect and works only with Poly's DA90 USB audio processor (or a 6-pin MDA526). It won't connect to standard 4-pin amplifiers or cords. If you aren't using a DA90, buy the standard convertible EncorePro HW540 instead.
The HW540D is convertible — it includes all three wearing styles in one headset. The HW510D is over-the-head only and the HW530D is over-the-ear only. All three are mono Digital-series headsets requiring the DA90; the HW540D is the one to choose when fit preferences vary across your team.
Yes — that's the point of the EncorePro HW540D. The same headset converts between over-the-head, over-the-ear, and behind-the-neck, so one part number suits every agent's preference. It simplifies procurement and inventory, and cuts the returns that come from issuing the wrong fixed style.
No. The "digital" in the EncorePro HW540D refers to SoundGuard DIGITAL hearing protection, not active noise cancellation. It has a noise-canceling microphone that keeps your background out of the caller's ear, but it does not electronically cancel ambient sound for the wearer.
The EncorePro HW540D is monaural — a single earpiece, leaving the other ear open for room awareness, in whichever of the three wearing styles you choose. For a both-ears (binaural) Digital-series headset, the EncorePro HW520D is the option.
