Poly EncorePro 320 Binaural Headset with Quick Disconnect – 77T26AA

The Poly EncorePro 320 Binaural Headset with Quick Disconnect (QD) (77T26AA) is a professional contact-centre headset designed for clear conversations, reliable performance and all-day comfort. Its binaural stereo configuration, flexible noise-cancelling microphone and voice-optimised audio make it suitable for customer service agents, call centres and business communications.

The headset features a noise-cancelling microphone designed to reduce unwanted background noise and support clearer voice communication. The microphone uses a flexible boom that can be adjusted to an appropriate position for voice pickup. HP specifies a microphone frequency response of 200Hz–6.8kHz.

The 30mm stereo speakers provide a voice-focused audio experience with a specified speaker bandwidth of 200Hz–6.8kHz. The binaural design delivers audio to both ears, helping users concentrate on conversations in busy contact-centre environments.

SoundGuard acoustic protection helps protect users against acoustic shock by limiting sound levels to below 118dBA. This provides an additional layer of hearing protection for users who spend extended periods handling calls.

The EncorePro 320 uses a Quick Disconnect (QD) connection rather than an integrated USB connector. This makes it suitable for use with compatible Poly QD adapters and supported desk-phone or PC configurations. The QD mechanism has been tested for more than 30,000 cycles, helping provide durability in high-use contact-centre environments.

The headset features soft, replaceable foam ear cushions and a lightweight design intended for extended wearing. The earcups can fold flat, allowing the headset to be worn around the neck between calls or stored more conveniently when not in use.

The 77T26AA is a TAA-compliant configuration and is compatible with PCs through a supported QD connection. It supports Windows 11, Windows 10 and macOS when used with compatible Poly connectivity hardware.

The headset weighs approximately 105g and uses a 762mm (30-inch) cable. Its black finish provides a professional appearance suitable for business and contact-centre environments.

The package includes the Poly EncorePro 320 headset and user guide. The product is backed by a Poly standard two-year limited warranty.
