Professional headset bundle for telephone use

The Plantronics SupraPlus HW251N 64338-31 arrives with a Polaris Cable 27190-01 that provides a quick-disconnect link to compatible amplifiers or USB-to-headset adapters. The monaural design delivers enhanced receive-side audio for accurate listening during long calls. This combination suits professionals who need a reliable wired connection throughout the working day.

Noise-cancel microphone and all-day comfort

A noise-canceling microphone reduces background sound so the caller hears clear speech in demanding environments. The wider headband and intelligent flexible boom are built for extended wear without fatigue. Wired operation draws no battery power and adds no wireless latency to the conversation.

Quick-disconnect flexibility for desk setups

The bundled Polaris cable lets the user step away from the desk while the call stays connected through the amplifier or adapter. Monaural coverage leaves one ear open to office surroundings. Buyers who need stereo coverage or a standalone USB connection without an amplifier should look at other configurations.

  • All-day comfort from lightweight SupraPlus design
  • Noise-cancel microphone for clearer calls

Questions about this item

How do I connect the HW251N headset to my desk phone using the 27190-01 Polaris cable?

Plug the headset's Quick Disconnect into the Polaris cable, then connect the cable's modular plug into the handset port or headset port of your compatible desk phone; the step often missed is seating the Quick Disconnect until it clicks.

Which parts of the 64338-31 bundle typically need replacement after heavy daily use?

The noise-cancel microphone windscreen, the ear cushion, and the Quick Disconnect latch on the Polaris cable 27190-01 are the wear items most often swapped during the headset's service life.

What is the first limitation I will hit when using the SupraPlus HW251N on back-to-back calls all day?

The mono design leaves one ear open, so ambient noise awareness becomes the limiting factor before the headset's own audio performance or comfort does.
