Good sound quality and value. If you plan on wearing your headset for long periods of time, I think this one might not be the best option. It tends to make the backside of my ear ache after about 30 minutes.

Easy to wear and optics are what i was looking for instead of the clunky head sets

This head set is awesome!! With a little tweaking and at this price you can't beat it!

well designed and easy to use.comfortable and great sound quality.

nice build quality

nothing if on sale

This is the first headset we have purchased for our front office coordinator, and it is great. We did purchase the lifter, which we were not sure we needed. Together they work great. Easy to install with directions, but did have to play with setting for echo and feedback at first.

This was a replacement for a similar Plantronics headset that was over 3 years old; I was excited that I could use my lifter and didn't y have to purchase a new one!! Plus it's a great price!! The seller was extremely fast shipping this headset

None!

First, why are the reviews the same for this product and the CS540? These are clearly (2) different products, but share the exact same reviews.

We use the Plantronics CS530 on our shop floor. They are ideal as users are free to move around the shop floor and answer the phone. Great sound quality and the battery life is superb for our work environment.

The sound quality is quite good as is the range. A longer battery life would be nice since they can't be replaced. We have about 65 of these units in the office and there aren't any signal problems between users.

Overstock had the best price that I could find and I recieved the items in a couple of days. Great products and service.
