EncorePro 525 USB-A Headset

The Poly EncorePro 525 is a wired stereo headset designed for hybrid workers who take calls from home or office. It connects through a USB Type A plug and offers binaural ear-cup coupling that can be worn over-the-ear or on-ear. A noise-cancelling omni-directional microphone helps keep voice transmission clear during meetings.

Upgrade from analogue or QD headsets

Moving to this USB-A model replaces older Quick Disconnect or analogue headsets that lack native Microsoft Teams integration. The jump is worth it when you need remote firmware updates, cloud management and a single hold button that controls both audio and video on USB models. It also brings full backwards compatibility for legacy equipment through the broader 500 series range.

Plug-and-play USB installation

Setup is straightforward: insert the USB-A connector into the PC and the headset is recognised without extra drivers. The 6.84 ft cable provides desk reach, though routing it across walkways can create a trip hazard. The inline controls are simple, but users unfamiliar with the single hold button may accidentally trigger audio or video actions during calls.

Questions about this item

Does the 6.84 ft cable reach a desktop USB-A port without an extension?

Yes, the 6.84 ft cable plugs directly into a USB-A port on a PC or hub, giving ample length for most desk setups.

How do I enable the single hold button for audio and video on Microsoft Teams?

Connect the USB-A plug, open Teams settings, select the headset as the default device, then press and hold the inline button to answer or end calls and toggle mute.

When should I replace the ear cushions on the EncorePro 525?

Replace the ear cushions when the foam loses its shape, the covering cracks, or hygiene becomes a concern after extended daily use.
