The Plantronics CS50 Headset
The CS50 wireless headset let's you leave your desk without leaving your calls behind

The Plantronics CS50 Wireless Office Headset System brings the ultimate in mobility and sound quality for hands-free conversations to your desk phone. Totally wireless, the CS50 gives you up to eight hours talk time and the wireless convenience to roam up to 300 feet while having secure conversations. The headset continuously charges in the cradle, and when in use, taking or ending a call is as simple as pressing a button. Compatible with typical office or PBX-based phones, the CS50 headset can be worn on either ear or over-the-head for maximum, long wearing comfort.

One-Touch Control for Mobile Multi-Tasking

Whether you're conferring with colleagues, walking to the printer, or pouring a cup of coffee, there's no need to interrupt important calls. The Plantronics CS50 works up to 300 feet from a desk phone. Its convenient operation allows you to answer, end, and mute calls on the headset with the touch of a button.

Noise-Canceling Microphone for Clearer Calls

An extended boom and noise-canceling microphone filter out background sounds for heightened speech clarity. Enjoy the audio quality of corded handsets, but without the tether.

Up to 8 Hours of Talk Time

The CS50 gives you up to 8 hours of unencumbered talk time and the option of remote answering (with Plantronics HL10 Handset Lifter, sold separately), making sure you'll never miss calls when away from your desk or workstation.

I ordered and received this headset from Amazon during the week of August 14th, and have been using it constantly since then. I have not experienced the problem with broken earpieces that others have been harping about, and my usage has been 3-8 hours a day, every day (minus a week of vacation in September).

I feel paranoid, though, and want to order extra earpieces from Plantronics as they do *look* flimsy.

I do have several gripes; one is that I get echo in the earpiece if I turn up the gain on the microphone too high, but I do not know if this is a problem with the headset, or my phone (Cisco 7960). Another nitpick would be to have some way to put the phone on/off hook w/o using the HL10--it's such an ugly hack...

All in all, the product performs perfectly as advertised, crystal clear communication, the earpiece is comfortable if you don't wear glasses (sometimes I don't wear my contacts and the earpiece can become uncomfortable with glasses on; the headband should rectify this, but I don't like headbands). This is a solid piece of kit that I would definitely recommend and buy again should the need arise.

PS. Why did Amazon raise the price on this lovely little item? ($165 -> $199) Regardless, this is still a great value.

I wanted to go handsfree at home, so I bought this product. The first thing I realized is that the cs50 wouldn't work with my cordless phone. That's because it takes as input the wire that connects the telephone handset to the telephone base unit. So I tried using my corded phone. But that wouldn't work either because the wire could not be removed, this is a problem with most phones where the keypad is not in the base but is in the handset. So I bought another $20 corded phone (29318GE1) and the cs50 worked with it, but the other party could not hear me well. I tried several other inexpensive phones but the clarity was not there. In desperation I tried an expensive phone (an $80 29486GE2), the kind one has in the office, and the cs50 worked much much better with it. I still could hear an irritating echo, but that went away after some tuning. My efforts paid off and I am now very happy with the clarity and the convenience.

I've had this headset for about 2 months. The mouthpiece is very lightweight, and the sound quality is excellent. The battery life is as advertised -- you can talk all day without needing to recharge. I also purchased the phone lifter to be able to answer calls while away from my desk. The unit comes with interchangeable over-the ear attachments and an over-the head attachment that snap onto the earpiece/mouthpiece unit.
The high points of the unit stop there. I was used to using an over-the-ear Plantronics Tristar, and was surprised to see that the earpiece on the CS50 simply sits next to the ear and does not have any earbud-type capability for making it easy to listen in noisy environments. The over-the-ear attachment for the CS50 is nowhere near as comfortable as the Tristar was, and I gave up and switched to the headset attachment.
The headset attachment was much more comfortable, and I quickly adjusted to the earpiece. For about two weeks I was very happy with the unit. Then the o-ring that attaches the headset to the earpiece snapped, making the headset attachment unusable. I was forced to switch to the over-the-ear attachment, as that was all I had left.
I slowly got used to the over-the-ear attachment, but have to say it is not comfortable to wear for an 8 hour day. The cushion over the top of the ear consists of hard rubber and makes my ear sore.
After using the over-the-ear piece for a couple weeks, the o-ring attaching to the earpiece snapped -- just like before! There is obviously a serious design problem with the CS50 -- look at the other reviews here.

I have used headsets for 15 years in my profession as a financial planner. I always buy the best, since I use it so frequently and it makes me more productive. I have held off buying a wireless headset, since I was worried about the quality of the sound and the convenience. Others require a belt pack or are heavy. This is amazingly small, voice clarity is superior (many of my callers have complemented me on the quality of the sound without knowing I'm on a wireless headset) and it makes it easy to move around a large commercial office possible, without interference. The previous reviewer is confused. The phone does beep in your ear when a call comes in, so you CAN answer the phone. Simply by pushing a button on the side, you can pickup or hangup the phone with the handset lifter, HL10. You cannot make calls unless you are at your phone, since there is no keypad on the headset. The other buttons allow you to mute the phone and change the volume. They have several ways to wear it; over the head, over the ear and behind the head. I was up and running in about 10 minutes. You can hardly tell you are wearing a headset, it is so light and unobtrusive. I wear it all day long. No more tangled cords or a putting caller on hold to get a file or get something from my assistant. Buy it and you won't be disappointed. This is the only product I have felt so strongly to write a review about, so far.
