Plantronics CS540 Spare Headset, No Charger Included

This is my 2nd headset of this model and luckily Ive bought the extended warranty each time. The first one was a full kit with the headset and base, after about 2 years of usage the mute/volume button on the back of the headset went bad. When trying to click the button to mute, it would repeatedly mute/unmute/mute multiple times from just a single click, then I began having issues with adjusting the volume. If I moved the switch up or down to change the volume sometimes it would make a loud screeching sounds and disconnect from the base. I would have to place the headset in the charging base and wait for it to connect and begin charging, then remove it from the base and turn it back on. Very inconvenient when this happens in the middle of a call. I got the headset only replaced under the warranty, kept the same base. After about 1 1/2 years the 2nd headset started exhibiting the exact same behavior with the mute/volume button so Im about to have to warranty it again. Its great that I have the warranty but I have to go without my headset for 1-2 weeks when I send it in. Other than the repeated issue, I love the headset. Has great sound quality, excellent range, and is comfortable to wear all day. Also has fantastic battery life.

Wrong item

Great Clarity of voice. battery lasted all day when I first purchased.It is about 2 months old now and Battery life has dropped slightly already. I charge it at lunch so I get the remainder of the day without the low battery beeping in my ear. My first headset lasted almost 3 years then developed a short in it. I already had the base so all I needed was the earpiece. Happy so far

I bought Plantronics WO2 more then 4 years ago. I am a creature of habit and dont want to change what I know works, especialy when it comes to my job. My dog eat my old headset and called the company who stated I needed to buy a newer model. I refused to believe that non of their other headsets would work with my system. So I bought this crossing my fingers. Low and behold it worked and I mailed back the newer model saving tons of money. It also charges on the stand and the spare batteries for the old headset also fit this device.
