Do you need the lightest wireless headset in the industry?
Choose your wearing style.
It’s so comfortable, you’ll forget you’re wearing a headset with the CS540. With two wearing styles included, you decide what’s best for your all-day wearing comfort. Using the over-the-ear configuration, it only weighs 21 grams, making it the lightest headset in the commercial grade industry.
Opting for the headband will provide a secure fit with a soft ear cushion sealing out sound from your environment, giving you a clear and crisp conversation with your caller.

One-touch controls for adjustments on the go.
Speaker volume & microphone mute controls are at your fingertips allowing you to adjust your CS540 headset remotely without returning to your desk. The silver call control button on the side of the headset, when pressed, will answer and hang up calls remotely when used with a compatible EHS cable or handset lifter.
When you freely move about your office, your environment constantly changes. That’s why it’s important to quickly increase your speaker volume if you move into a loud environment. Or maybe you need to converse with a co-worker, and muting your microphone is required. With one-touch controls, you can concentrate on your caller, not your headset.
Fast and Easy Setup.
Setup only takes a few minutes as you configure compatibility, microphone, and speaker volume controls. Base settings are easily configurable to maximize your audio experience. You will find a 4-position dial for your major speaker volume setting. Your headset also has a speaker volume adjustment, for minor call-to-call changes.
Also on the base, you have a 6-position microphone dial allowing you to adjust the outgoing voice volume that callers hear. Last on the base is the compatibility slide switch with the letters A-G. The default setting is ‘A’ which works with most phones. If you experience no sound, slide the switch to other letters until the headset works correctly.
Productivity Booster.
Above all, if you’re serious about getting more done in a busy work day, going wireless allows you to roam your office while you talk. Ever need to grab a file while on a call? How about needing paper for your printer? Need to ask a co-worker a quick question down the hallway?
With up to 350 feet of range to roam your office, you’ll improve productivity as you’re able to gather information throughout your office while continuing to talk.
