Experience crystal clear audio with the lightweight Plantronics CS540 convertible wearing style for a customized fit. Includes your choice of a headband and three different ear hooks to switch between. This wireless headset is built sturdily enough to handle everyday use while the technology itself incorporates some of the latest features for headsets. 

Out of the box you'll be able to connect with 98% of corded desk phones for hands free wireless freedom up to 350 feet away from your desk.

Up to 7 hours of battery on a single charge will last most of your work day. Place the headset in the charging base at lunch or on break and you'll have easily over a full day of charge. 

Office work is more pleasant with the Plantronics CS540's noise cancelling microphone so users and customers on the other end can carry on a pleasant conversation without excess background noise.

    There is a lot of static on my new Plantronics CS540 headset.

    Hi Paulette, please contact our support team to help resolve this. Keep in mind, you also have a 1 year warranty in the case the headset needs to be replaced under the warranty.

    Good overall for cordless phones. I wish the speaker went a bit louder...then again, my hearing isn't what it used to b! Solid option for cordless phones.

    Works great!!

    This headset allows me to be anywhere in our small office & answer the phone! Love the flexibility! Only thing I don't like is it does pinch my head-and I do NOT have a big head! (gives me a minor headache by the end of the day)
