Poly EncorePro 545 USB Convertible Headset + USB-C/A
PRODUCT DESCRIPTION
Poly EncorePro 545 USB Convertible Headset + USB-C/A (783R4AA) - Local Warranty
Poly EncorePro 545 USB Convertible Headset — Three Wearing Styles, One SKU
The Poly EncorePro 545 is the convertible model in HP’s EncorePro 500 USB range. HP’s specification lists the headphone type simply as “Convertible”; the HP-hosted EncorePro 500 USB Series user guide is more specific, instructing the user to “choose a headset wearing style and assemble your headset for over-ear, over-head or behind-head”. One part number therefore covers three different preferences, which is why it is the usual choice for hot-desking and shared positions.
The Lightest EncorePro at 32 g
HP publishes a headset weight of 32 g for this part number — against 52 g for the mono EncorePro 515 and 74 g for the stereo 525. For staff who wear a headset all day, that difference is the whole argument for a convertible: it is the least headset you can have on your head and still have a noise-cancelling boom in front of you.
Noise-Cancelling Microphone and SoundGuard Digital
The acoustic specification matches the rest of the 500 USB range: a noise-cancelling microphone running 35 Hz to 21 kHz, a 30 mm speaker covering 20 Hz to 20 kHz, sensitivity of -40 +/-3 dB, signal-to-noise ratio above 53 dB, and a 135 mm boom rotating 290°. SoundGuard Digital provides the acoustic limiting that makes a headset safe to wear for a full shift of calls.
USB-A and USB-C, on a Slightly Longer Cable
HP lists a 2180 mm cable for the 545 — just under 10 cm longer than the 2085 mm cable on the other 500 Series USB models. HP’s compatibility statement reads “compatible with PCs via USB Type-A cable or USB Type-A/C adapter”, and the EncorePro 500 Series page describes built-in USB-A and USB-C connectors on the same cable, so one SKU covers both older desktops and USB-C-only laptops.
Buying the Poly EncorePro 545 in Singapore
SourceIT supplies the Poly EncorePro 545 USB to Singapore businesses with local warranty and a GST invoice. It is the model we most often recommend for shared desks and flexible seating, because one part number satisfies staff who each want to wear it differently. Ask us for volume pricing on a rollout.

Compatibility & Software Support
Operating systems
HP lists Windows 11, Windows 10 and macOS as the supported operating systems for this part number. The headset presents itself to the computer as a standard USB audio device, so it is recognised without a driver install — which is what makes it practical to hand out across a floor of mixed Windows and Mac machines.
Softphones and meeting platforms
HP describes this model as “certified to work with top virtual meeting providers” but does not publish a named Microsoft Teams certification for this exact part number. Because it presents as a standard USB audio device it is selectable in Microsoft Teams, Zoom, Webex, Genesys, Avaya and other softphones. If your tender requires a certified Teams device, order the EncorePro 515-M or 525-M instead — there is no -M variant of the 545.
USB-A and USB-C
HP’s compatibility statement for this part number reads “compatible with PCs via USB Type-A cable or USB Type-A/C® adapter”, and HP’s EncorePro 500 Series page describes “built-in USB-A and USB-C connectors on the same cable”. In practice that means the same headset covers an older desktop with USB-A ports and a newer USB-C-only laptop without buying a separate dongle — useful in Singapore offices that are part-way through a hardware refresh.
Poly Lens device management
HP lists Poly Lens support for the EncorePro 500 Series. Poly Lens is HP’s cloud device-management service: it lets IT see which headsets are deployed, push firmware and settings, and check device health across sites, rather than chasing individual desks. For a contact centre standardising on one model this is the difference between a managed estate and a drawer of unknown hardware.
Package Contents & EncorePro USB Series Ordering Information
In the box
- Poly EncorePro 545 USB convertible headset (assembles for over-ear, over-head or behind-head wear)
HP lists the box contents for this part number as the headset only. No adapter, amplifier or carrying case is included — none is needed, because the headset terminates in USB. The wearing style is changed by reassembling the parts supplied with the headset, per HP’s user guide.

Frequently Asked Questions — Poly EncorePro 545 USB
What wearing styles does the convertible EncorePro 545 support?
HP’s specification lists the headphone type as “Convertible”. The HP-hosted EncorePro 500 USB Series user guide instructs the user to “choose a headset wearing style and assemble your headset for over-ear, over-head or behind-head” — so three styles, changed by reassembling the parts supplied in the box rather than by buying anything extra.
Why choose the 545 over the 515 or 525?
Two reasons. First, weight: HP publishes 32 g for the 545 against 52 g for the mono 515 and 74 g for the stereo 525. Second, choice: on a hot-desked or shared floor one part number satisfies staff who each prefer a different fit, which keeps the stockroom simple. Choose a fixed style instead if you want the ear coverage of a stereo headset for concentration.
Is the EncorePro 545 certified for Microsoft Teams?
HP does not publish a Microsoft Teams certification for this exact part number — it describes the model only as certified to work with top virtual meeting providers. There is no -M variant of the 545. If certification is a procurement requirement, choose the EncorePro 515-M or 525-M. We would rather flag that now than have a device fail a compliance check later.
Is there a convertible model in the Quick Disconnect range?
Yes — the EncorePro 540 QD Convertible and the 540D Digital QD. Those connect to a desk phone or PC through a separate Poly adapter rather than terminating in USB.
Do I need an adapter, amplifier or licence?
No. It terminates in USB and is bus-powered — no amplifier, no power supply, no battery, no licence.
Which operating systems does HP support?
HP lists Windows 11, Windows 10 and macOS for this part number, and no driver installation is required.
Does the Poly EncorePro 545 USB come with a Singapore warranty?
Yes. Every Poly EncorePro 545 USB sold by SourceIT comes with local Singapore warranty and a GST invoice.
