Poly WH500-XD Convertible Spare Headset for CS540-XD/CS545-XD Sets

The Poly 89549-01 is a convertible spare headset designed for users who already own a Poly CS540-XD or CS545-XD wireless system and need an additional or replacement headset. It connects over the 900 MHz spectrum, pairing seamlessly with the existing base to give you freedom to roam up to 350 feet from your desk without dropping a call. Because it is supplied as a headset only, setup is as simple as registering it to the base you already have.

At the heart of the design is a boom microphone that cancels background noise and relies on digital signal processing to keep your voice clear and natural. The SoundGuard feature helps protect your hearing by limiting sudden spikes in volume above 118 dBA, a detail that matters during long days of back-to-back conversations.

You can choose how you wear the headset. Use the discreet ear clip when you want as little weight as possible, switch to the headband when you prefer a more secure fit, or go with the neckband if that feels more balanced. No matter which option you select, the on-ear, mono speaker lets you stay aware of what is happening in the room while still focusing on the person at the other end of the call.

The battery supports up to six hours of talk time, which is enough for most workdays that involve frequent check-ins, virtual meetings, or customer support sessions. If you handle calls in a busy sales floor, an open office, or a home workspace where you need to move around freely, this spare headset lets you maintain productivity without being tethered to your desk.
