Save big on the Plantronics CS540-XD Wireless Headset (88283-01) — the high-density 900 MHz office headset built for environments where standard DECT headsets cause interference. Grade A+ refurbished by Reef Telecom with a 10-year warranty, so you get like-new performance at a fraction of the cost.

⚠️ Note: This headset connects to desk phones only — it does NOT support USB or computer connections. Need USB? Check out the Plantronics Savi W740.
