Wired mono headset for wideband VoIP

The Plantronics HW251N SupraPlus is a wired monaural headset built for wideband VoIP communications. Its noise-cancelling boom microphone reduces background sound while the over-the-head design keeps the single earpiece secure during long calls. A 3.94 ft cable connects directly to compatible desk phones or adapters. The headset weighs approximately 1.38 oz for lightweight daily use.

Suited for single-ear office use.

This headset serves professionals who must stay aware of their surroundings while handling voice calls. The mono earpiece leaves one ear open for colleagues or announcements. Buyers who need stereo audio for multimedia, a wireless connection for mobility, or an in-ear wearing style should consider other form factors. The fixed boom microphone also limits use cases where a hidden or removable mic is preferred.

3.94 ft cable length determines desk reach

The supplied cable measures 3.94 ft end to end, setting the maximum distance between the user and the phone or adapter port. Verify that this reach covers your workstation layout before purchase. No extension cable is included in the package. The length is a fixed physical constraint that cannot be altered without an additional accessory.
