Poly EncorePro 320 QD Stereo Headset
PRODUCT DESCRIPTION
Poly EncorePro 320 QD Stereo Headset (214573-01 / 77T26AA) - Local Warranty
Poly EncorePro 320 QD Stereo Contact Centre Headset
The Poly EncorePro 320 with Quick Disconnect is the binaural (stereo) model in Poly's EncorePro 300 Series — HP publishes it as the "EncorePro 320 with Quick Disconnect Binaural Headset TAA". Both ears are covered, which is what phone teams on a busy Singapore contact-centre floor ask for when concentration and call accuracy matter.
Flexible Noise-Cancelling Microphone and SoundGuard Protection
HP specifies a flexible noise-cancelling boom microphone across the EncorePro 300 Series, so the agent's voice reaches the caller without the floor behind them. SoundGuard protects against acoustic shock by limiting sounds to below 118 dBA — a standard requirement for staff who wear a headset through a full shift.
Quick Disconnect Rated for More Than 30,000 Cycles
The Poly Quick Disconnect connector is rated by HP at more than 30,000 cycles. An agent unplugs at the ear and walks away with the headset while the cable stays at the desk — the reason QD remains the default on shared and shift-based contact-centre positions. The matching QD cable or amplifier is ordered separately; send SourceIT your desk phone model and we will quote the correct one.
TAA Compliant, Repairable, Fold-Flat
HP's product name confirms this is the TAA-compliant build, which matters for government and regulated tenders. Soft, replaceable ear cushions keep a long-running fleet serviceable, and fold-flat earpieces let agents rest the headset around the neck between calls.

Frequently Asked Questions — Poly EncorePro 320 QD
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 QD certified for Microsoft Teams and Zoom?
HP lists the EncorePro 300 Series as Certified for Microsoft Teams, Certified for Zoom and Certified for Chromebook. On a QD headset the platform behaviour depends on the QD cable, amplifier or desk phone it is plugged into, so tell us your phone model and we will confirm the right cable.
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 QD come with warranty in Singapore?
Yes. Every Poly EncorePro 320 QD sold by SourceIT comes with local Singapore warranty and a GST invoice.
