Plantronics SupraPlus Wideband NC Headset

The Plantronics PL-HW251N 64338-31 SupraPlus Wideband NC is a monaural mobile electronics accessory built for wideband VoIP communications. It features a noise-canceling microphone and an over-the-head design intended for all-day comfort. Quick disconnect functionality requires a separate PL-M22 amplifier.

Suited for office users needing wideband audio

This headset suits professionals who rely on wideband telephones for clearer calls in noisy environments. It is not suited for users who need a binaural wearing style or a headset that connects without an additional amplifier. Buyers wanting a self-contained USB or analogue solution should look elsewhere.

Requires PL-M22 amplifier for operation

The single specification that decides fit is the quick-disconnect interface which mandates the PL-M22 amplifier, sold separately. Without this specific accessory the headset cannot function. Verify amplifier availability before purchase.

Questions about this item

How do I connect the quick-disconnect plug to a phone?

Plug the headset into a PL-M22 amplifier (sold separately), then connect the amplifier to the phone's handset port; the step often missed is seating the quick-disconnect firmly until it clicks.

Which part will wear out first with daily use?

The ear cushion and microphone windscreen are the consumable items; Plantronics sells replacement pads and screens for the SupraPlus line.

What limits call clarity during long sessions in a noisy office?

The noise-cancelling microphone reduces background sound, but extreme ambient noise can still exceed its rejection capability and degrade wideband audio fidelity.
