Poly EncorePro 320 USB Stereo Headset USB-C
PRODUCT DESCRIPTION
Poly EncorePro 320 USB Stereo Headset USB-C (214571-01 / 767F9AA) - Local Warranty
Poly EncorePro 320 USB-C Stereo Headset with 30 mm Drivers
The Poly EncorePro 320 Stereo USB-C is the binaural, USB-C model in Poly's EncorePro 300 Series and the one HP still publishes a full specification table for. Thirty-millimetre drivers cover both ears with a 20 Hz – 10 kHz response, and the headset plugs straight into a USB-C laptop or dock with no adapter, amplifier or licence.
EncorePro 320 USB-C Specifications: 0.07 kg, 2,190 mm Cable, 290° Boom
HP publishes a weight of 0.07 kg, dimensions of 11.1 x 14.9 x 6.7 cm, a 2,190 mm cable and a boom microphone that rotates through 290° so it can be worn on either side. The noise-cancelling microphone is rated at -38 ±3 dB sensitivity. The headset is CE marked and TAA compliant.
Foam Ear Cushions and On-Ear Stereo Comfort
The on-ear supra-aural stereo design with foam ear cushions is built for staff who are on calls all day. Cushions are replaceable, so a worn headset becomes a consumable repair rather than a fleet replacement — a meaningful difference in total cost across a Singapore contact centre.
Works with Windows 11, Windows 10 and macOS
HP lists compatibility with Windows 11, Windows 10 and macOS. The headset presents as a standard USB audio device, so it works with whichever softphone your team runs, and HP lists the EncorePro 300 Series as Certified for Microsoft Teams, Zoom and Chromebook.

Frequently Asked Questions — Poly EncorePro 320 USB-C
What is the difference between the EncorePro 310 and the EncorePro 320?
The EncorePro 310 is monaural — one earpiece, so the user stays aware of the room. The EncorePro 320 is binaural (stereo) with both ears covered, which helps concentration on a noisy contact-centre floor. Everything else about the two models is the same family design.
Should I order the Quick Disconnect (QD) or the USB version?
Order QD if the headset plugs into a desk phone or an existing headset amplifier — the QD connector lets staff unplug at the ear and walk away, and HP rates it for more than 30,000 cycles. Order USB if the user works from a computer softphone and you want a single cable with no adapter. SourceIT stocks both: the QD models and the USB models.
Which USB connector do I need — USB-A or USB-C?
Match it to the machine. SourceIT lists this headset in both: USB-A and USB-C. There is no functional difference beyond the plug, so it comes down to what your laptops and docks provide.
Is the Poly EncorePro 320 USB-C certified for Microsoft Teams and Zoom?
HP lists the EncorePro 300 Series as Certified for Microsoft Teams, Certified for Zoom and Certified for Chromebook. The USB models plug straight into the computer and present as a standard USB audio device.
Does it protect users from acoustic shock?
Yes. HP specifies SoundGuard across the EncorePro 300 Series, protecting against acoustic shock by limiting sounds to below 118 dBA — a standard requirement for Singapore contact-centre deployments where staff wear a headset all day.
Can I replace the ear cushions instead of replacing the headset?
Yes. HP specifies soft, replaceable ear cushions on the EncorePro 300 Series, which keeps the cost of a long-running contact-centre fleet down. Ask SourceIT for the current cushion part number for this model.
How does the EncorePro 300 Series compare with the EncorePro 500 Series?
The 300 Series is the value tier. The 500 Series — for example the Poly EncorePro 510 QD Mono or the Poly EncorePro 525 USB Stereo — sits above it in the EncorePro range. If you are comparing the two for a tender, contact SourceIT and we will put the published specifications side by side.
Does the Poly EncorePro 320 USB-C come with warranty in Singapore?
Yes. Every Poly EncorePro 320 USB-C sold by SourceIT comes with local Singapore warranty and a GST invoice.
