Poly (Plantronics) CS540 Spare Headset

Poly (Plantronics) CS540 Spare Headset

The Poly (Plantronics) CS540 Spare Headset is a replacement wireless headset for users who already have a compatible CS540 system. Whether your current headset is damaged, missing, or no longer comfortable to wear, this spare unit lets you replace the headset while continuing to use your existing charging base.

Its lightweight, convertible design gives you the flexibility to wear it over the ear or over the head, depending on your preference. The noise-canceling microphone helps reduce surrounding noise during conversations, making it suitable for receptionists, office professionals, and customer service teams who spend much of their day handling calls. DECT wireless technology provides a range of up to 350 feet under suitable conditions, while the battery supports up to seven hours of talk time. 

If you need other components for your existing setup, you can find compatible options through our Replacement Parts selection and explore additional products in our Headset Accessories section.

Compatibility Information

This spare headset is designed for the standard Plantronics CS540 system. It includes a replacement battery, but the charging base is sold separately. Confirm that your existing system is the standard CS540 rather than the CS540-XD before ordering, as the two versions use different wireless technologies.
