First we made it lighter. At only 21 grams, the CS500 Series features the lightest DECT headset on the market (CS540). That means all-day comfort for all-star performance.

Then we made it better. Increased range for maximum mobility, one-touch controls, energy efficient power management, simple plug-and-talk installation the CS500 Series does it all.

Make a good call with the new standard in wireless desk phone headset systems.

Rated 5 out of 5 by from Disappointing!This was bought for me by my company and compared to the previous Plantronics headset that I was using this is sub par! Even with the volume up completely everyone on the other end complains that they cannot hear me or I sound like I'm in a vacuum and very far away. Even though its lighter than the previous one it is way more awkward and does not fit around my ear as comfortably as the other one did. I would just switch back to my old one but the battery life is down to less than 6 hours and you can't get replacements for it any longer. I am very disappointed in this version headset and can't wait til it no longer works so that my company will find an alternate one to purchase for me!!!

Rated 5 out of 5 by from Headset nice, earloop needs much improvementThe whole purpose of a headset is to be able to use both hands while talking on the phone for extended periods of time. This is a very nice headset, however, the rigid ear loop is painful immediately when put on. The thin foam cushion does nothing to improve the comfort of the rigid plastic ear loop on the back of the ear. A softer, more flexible material should be used for the ear loop itself or supply a softer, denser foam cushion. Also, the one-size-fits-all ear tip does not fit well in the ear. Needs better shape and possibly small, medium and large sizing to fit various size ear canals.

Rated 5 out of 5 by from Good fit so farWe bought two different models and this in ear model WON OUT at our business. Really like the quality and customers are no longer complaining about not being able to hear us talk. Nice product.

Rated 5 out of 5 by from HappyOur old headsets needed replaced, and choose this one. We've had them about 2 weeks and love them. Volume on ear piece is great, clear reception on both ends. Would recomment

Rated 5 out of 5 by from AwesomeI have been using since November. Great sound quality. Comfortable. Love the option of the over-the-head or the over-the ear. As well it is completely reversible for using in either ear.
