First - these headsets DO NOT work with a CORDLESS phone. They are meant for a desk type phone with a handset. You must spend another $ for an adapter-cable to use the headset with a cordless, non-handset phone.That wouldn't have been so bad, but the performance was not in the $ price class of this...

Much better than the CS55, this lighter weight design adds much more comfort, with improved sound quality. This unit is great if you spend a lot of time on the phone, or even for the "marathon" phone conferences.

Love this product but should not be sold without the handset lifter. The range is excellent but you cannot answer the phone from that far without the handset lifter. You have to manually take the phone off the hook to answer or make calls. Really should be sold only with the lifter.

The item arrived a day after the date promised by the Staples website. The item arrived "open" - the plastic bag containing some parts was torn open, the cord was crudely rewound, and the instructions were missing. Fortunately, the instructions could be found on line.

Being able to swap between headset and earpiece is great, a very innovative design idea for wireless headsets. Still has the same great plantronics quality too.

My company has bought at least a dozen of these headsets. They have never given us any problems and work perfectly. The sound quality is great and the convenience and ease of use is awesome. I don't think headsets should cost this much money, but this store has the best price at least!

First of all, Plantronics is the best for quality headsets, but I'm not sure I like this new model. I purchased the CS540 to replace the CS50 that I used for almost 10 years. What I like about the new model; (1) Sleek, more modern design (2) Non-slip base (3) Lighter headset, almost weightless What...

A very good price for an excellent quality product. Set up doesn't take long and the headset is easy to use and comfortable to wear. Sound is very clear though it takes a while to get used to the slight delay between picking up the call and the customer being able to hear you.

In our business it is great to have our hands free while we are on the phone with our customers. We often need to get up to obtain a loan file, or to walk across the office to speak with another colleague while we are on the line.

Great product, use it everyday. Being able to switch between office phone and voip / Isofthpone is a great feature. If you use a voip line remember your quality of interspeed can be a determining factor for your quality of sound.
