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. 

Finally, you're covered with a one-year advanced replacement warranty for peace of mind. That means one year of our support: if our team determines that your Plantronics CS540 is defective, we'll ship a replacement that same day and cover the shipment cost to do so.

    Battery life

    I was so excited when I got this set , it was going to be the answer to all my worries about working and being mobile. That however change shortly. The battery dies out so fast it defeats its purpose, it runs out like every 3 hours , you’ll be in a lot of trouble if you work in a call center. The battery life is not designed for working use period!

    This headset is not as good as the previous company provided headset I had but it is doing the job.

    Love it except the battery time

    I put my headset on at 8AM and finish at 3:30 but it usually dies around 2. I was told that I should let it charge during my lunch break, but I don't take a lunch break so it's a little frustrating. Other than that, I love the headset.
