Poly EncorePro 540 Digital QD Convertible Headset
PRODUCT DESCRIPTION
Poly EncorePro 540 Digital QD Convertible Headset (HW540D) - Local Warranty
EncorePro 540D Digital QD Contact-Centre Headset
The Poly EncorePro 540D is the convertible member of the EncorePro 500 Series in the digital Quick Disconnect build. HP classifies it as a convertible headset, so a single part number covers more than one way of wearing it — useful when you are buying for a team rather than for one person.
Noise-Cancelling Microphone and Wideband Audio
HP specifies a noise-cancelling boom microphone running 150 Hz to 6.8 kHz, on a boom that is 135 mm long and rotates through 290° so it can be positioned correctly on either side of the head. The receive side uses a 30 mm speaker covering 150 Hz to 6.8 kHz of wideband audio — the range that carries speech clearly on a long shift.
Hearing Protection Across a Full Shift
Every EncorePro 500 Series Quick Disconnect headset carries Poly SoundGuard acoustic limiting. HP's own EncorePro 500 Series documentation puts the maximum acoustic output of the QD models at 118 dBA, which is the protection that matters when an agent takes hundreds of calls a week and a line fault or a feedback squeal can arrive without warning. Note that the further protections Poly groups under SoundGuard DIGITAL — anti-startle and time-weighted average daily noise exposure — come from the DA-series USB audio processor rather than from the headset itself, so the adapter you pair this with matters for workplace-safety compliance.
Why It Suits EncorePro 540D Teams
Convertible is the practical answer to a shared desk or a mixed team. Rather than stocking three different headsets and hoping you guessed right, you issue one part number and let each agent set it up the way they prefer. At 32 g it is among the lightest wired headsets Poly builds.
Digital Quick Disconnect: What You Also Need to Order
This is a Quick Disconnect headset, which means it is the headset half of a two-part system: it has no USB plug and no 3.5 mm jack of its own, and it will not connect to a computer or a desk phone on its own. It clicks into a Poly QD audio processor or amplifier, which is what actually plugs into the PC or the phone. The advantage is that an agent can unclip and walk away in a second, and the adapter stays at the desk for the next shift. This model is the digital (“D”) build of the EncorePro 500 Series, so confirm the matching adapter with SourceIT before you order — Poly's digital QD headsets and the standard analogue QD headsets do not take the same adapter. We will quote the correct one for your phone system or softphone.

Compatibility & Software Support
Platforms, Adapters and Operating Systems
| Connection Method | Poly Quick Disconnect. The headset connects to a Poly QD audio processor or desk-phone amplifier, which in turn connects to the computer or the telephone. |
| Computer / Softphone | Through a Poly QD USB audio processor. HP's DA Series USB Audio Processor guide covers the DA75, DA85 and DA85-M and states they connect with Poly and Plantronics EncorePro 300, 500 and 700 Series Quick Disconnect headsets. |
| Digital vs Analogue QD | This listing is the digital (“D”) build. Poly's digital QD headsets and its standard analogue QD headsets are not interchangeable on the same adapter — ask SourceIT to confirm the pairing before ordering. |
| Desk Phone | Through a Poly QD telephone amplifier appropriate to the handset. Some desk phones also accept a direct-connect QD cable. |
| Operating Systems | Windows 11, Windows 10 and macOS, via the QD audio processor. |
Certification Note
HP does not publish a Microsoft Teams certification for this headset. In the EncorePro range, Teams certification is carried by the Teams (“-M”) models and by the DA85-M audio processor rather than by the analogue or digital QD headsets, so if Teams certification is a procurement requirement, tell SourceIT and we will quote a combination that meets it.
Management
Poly Lens is HP's free management and firmware application for Poly devices on Windows and macOS. On a corded QD system the manageable device is the USB audio processor rather than the headset, so fleet firmware and settings follow the adapter.

Frequently Asked Questions — Poly EncorePro 540D
What is the difference between the Digital QD and the standard QD version of the EncorePro 540?
They are the same headset acoustically — the difference is the Quick Disconnect connector, and therefore which Poly adapter they mate with. Poly's digital QD build and its standard analogue QD build are not interchangeable on the same audio processor. If you already have adapters at the desks, tell us which ones and we will match the headset to them; if you are buying from scratch we will quote headset and adapter together.
Do I need to buy anything else to use this headset?
Yes, and this is the single most common ordering mistake with Quick Disconnect headsets. The headset has no USB plug and no 3.5 mm jack. It requires a Poly QD USB audio processor to reach a computer, or a Poly QD telephone amplifier to reach a desk phone. Neither is in the box. SourceIT will quote the right adapter alongside the headset — just tell us what the agents are calling from.
How does this compare with the headband models in the range?
The EncorePro 510D (52 g, one ear) and EncorePro 520D (74 g, both ears) are conventional over-the-head headsets with foam cushions. This model is the lighter, less obtrusive option in the same series, with the same noise-cancelling microphone and the same SoundGuard acoustic limiting.
How much acoustic protection does it give agents?
Poly SoundGuard acoustic limiting is built into the headset, and HP publishes a maximum acoustic output of 118 dBA for EncorePro 500 Series QD models. If your workplace-safety policy also requires anti-startle or daily noise-exposure (time-weighted average) limiting, those sit in Poly's SoundGuard DIGITAL feature set, which is delivered by the DA-series USB audio processor rather than by the headset — so specify the adapter carefully. SourceIT can advise on a combination that meets a contact-centre duty-of-care requirement.
Is it certified for Microsoft Teams?
HP does not publish a Microsoft Teams certification for this headset. In the EncorePro range, Teams certification is carried by the Teams (“-M”) models and by the DA85-M audio processor. The headset itself works with Teams as a standard audio device through the QD adapter, but if formal certification is written into your tender, tell SourceIT and we will quote a combination that satisfies it.
How does the EncorePro 500 Series compare with the 700 Series?
The 500 Series is the volume workhorse: foam ear cushions, 30 mm speakers, six axes of adjustment and a durable cable with aircraft-grade aluminium joints. The EncorePro 710 and EncorePro 720 are the premium range, built from nylon composite with a reinforced headband, artificial-leather cushions, 28 mm speakers and an extendable boom, and they ship with a carry case. Both series publish the same 150 Hz to 6.8 kHz speaker bandwidth — the 700 Series is about build, comfort and finish rather than a different audio specification.
Can we buy these in volume for a contact centre in Singapore?
Yes. SourceIT supplies Poly headsets to Singapore contact centres, government agencies and enterprises, and we can quote headsets and QD adapters together, hold stock against a rollout schedule, and issue a GST invoice against a purchase order. Email us with the agent count and the phone or softphone platform and we will put a configuration together.
Is there a local Singapore warranty on the Poly EncorePro 540D?
Yes. Every Poly EncorePro 540D sold by SourceIT comes with local Singapore warranty and a GST invoice.
