Poly EncorePro 525 USB Stereo Headset + USB-C/A
PRODUCT DESCRIPTION
Poly EncorePro 525 USB Stereo Headset + USB-C/A (783R3AA) - Local Warranty
Poly EncorePro 525 USB Stereo Headset — Specifications at a Glance
The Poly EncorePro 525 is the dual-ear USB model in HP’s EncorePro 500 contact-centre range. HP publishes the full datasheet for this part number: a noise-cancelling microphone running 35 Hz to 21 kHz, 30 mm speakers covering 20 Hz to 20 kHz, microphone sensitivity of -40 +/-3 dB with a signal-to-noise ratio above 53 dB, and a 135 mm boom rotating 290°. It weighs 74 g on a 2085 mm cable — 22 g more than the single-ear 515, which is simply the second earcup.
Dual-Ear Focus on a Busy Floor
Covering both ears is the point of a stereo contact-centre headset. On an open floor it cuts the surrounding conversation the agent has to work past, which shows up as fewer repeats, shorter calls and less listening fatigue by the end of a shift. Where a floor-walker or supervisor wants one ear free, the single-ear EncorePro 515 is the same headset in monaural form.
Noise-Cancelling Microphone and SoundGuard Digital
HP specifies a noise-cancelling microphone and SoundGuard Digital acoustic protection on this part number. The noise-cancelling boom is what keeps the customer hearing the agent rather than the room; SoundGuard Digital is the acoustic limiter that protects the agent from sudden level spikes across a full shift. For Singapore employers with duty-of-care obligations to call-handling staff, the second one is a requirement rather than a feature.
USB-A and USB-C on One Cable
HP’s EncorePro 500 Series page describes built-in USB-A and USB-C connectors on the same cable, and the compatibility statement for this part number reads “compatible with PCs via USB Type-A cable or USB Type-A/C® adapter”. One SKU therefore covers both the legacy USB-A desktops and the USB-C-only laptops on a floor that is mid-refresh.
Buying the Poly EncorePro 525 in Singapore
SourceIT supplies the Poly EncorePro 525 USB to Singapore businesses with local warranty and a GST invoice, and quotes volume pricing for contact-centre rollouts. Most floors end up ordering a mix — stereo for seated agents, mono for supervisors — and we are happy to price both on one order.

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 does not publish a named Microsoft Teams certification for this part number — that is the EncorePro 525-M. HP describes the 525 as optimised for major virtual meeting platforms, and 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 525-M instead.
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.

Frequently Asked Questions — Poly EncorePro 525 USB
What is the difference between the EncorePro 525 and the 525-M?
The 525-M is the Microsoft Teams certified build, with a dedicated Teams button on the inline control. The 525 on this page has no published Teams certification. Every published acoustic and mechanical figure is identical — same 30 mm speakers, same 35 Hz to 21 kHz microphone, same 74 g weight.
Should I choose the stereo 525 or the mono 515?
Stereo (dual-ear), as here, covers both ears and helps agents concentrate on a noisy open floor. Mono leaves one ear free so staff stay aware of the room — usually preferred by supervisors, floor-walkers and anyone moving between calls and desk work. The mono equivalent is the EncorePro 515, and the convertible EncorePro 545 lets each user pick their own wearing style.
How does the EncorePro 500 range compare with the 700 range?
HP positions the 700 range above the 500. The published specifications differ: the 500 models use 30 mm speakers rated 20 Hz to 20 kHz with foam ear cushions, while the 700 models use 28 mm speakers rated 150 Hz to 6.8 kHz with artificial-leather cushions and an extendable 120–145 mm boom, and are published by HP as TAA builds. The 700 Series stereo USB equivalent is the EncorePro 725 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. That is the practical difference from the Quick Disconnect EncorePro models, which cannot connect to anything without a separate adapter.
What accessories should I order with it?
Replacement ear cushions are the usual consumable, particularly on shared or hot-desked positions where they are changed periodically for hygiene. Ask us to include spares in a rollout quote.
Which operating systems does HP support?
HP lists Windows 11, Windows 10 and macOS for this part number. It is recognised as a standard USB audio device, so no driver installation is required.
Does the Poly EncorePro 525 USB come with a Singapore warranty?
Yes. Every Poly EncorePro 525 USB sold by SourceIT comes with local Singapore warranty and a GST invoice.
