Excellent headset!
We've been using these headsets with our Polycom office phones for the last 3-4 months and the work very well. These are probably the best wireless headsets I've ever used. Here are the things I like about them: 1) These are light-weight & comfortable. Since I often wear mine for 10-12 hours a day, this is very important. 2) The sound quality is excellent. It really is like talking directly on a wired headset. 3) One major problem I've had with Plantronics headsets in the past is that they aren't very good with eliminating wind noise. Fortunately, these perform very well in this area. I can talk just fine under a ceiling fan or walking outside by the shop with no issues. 4) Having an effective wireless headset really frees me up to get stuff done while on the phone all day. 5) The range is very good. We can walk all over a 3000 square foot space without issues. It does reach the edge of its range when we go out to the outdoor shop; but, that should probably be expected. Even though I love this headset overall, there are a few issues: 1) By default, the headsets come with a cable that hooks up just fine with Polycom phones - but they don't support the answer/hang-up button on the headset. That basically means you have to be by the phone to either answer or hang up from a call. The best way we found to resolve this is to use the Plantronics 38439-11 EHS Cable , which is a great addition to this phone. The downside is that it's kind of expensive for just a cable... 2) There are multiple people working in a small space, and I'm regretting that everyone else has so much mobility. I mean, come on! It's OK for me to pace all over the office, but not everyone else. :) Overall, I would highly recommend this headset to anyone who is using an office phone and doesn't want to be tied down to their desk all day - especially if you spend a lot of time on the phone.

Another top notch headset from Plantronics, well worth the extra cost
Oct 2016 I bought a CS540 to replace my aging CS70NC that was failing fast. I looked into replacing the battery, and maybe the crumbling earpiece, but the cost was more than I wanted to spend to rehabilitate old stuff. I had been very satisfied with my old Plantronics unit and was glad to see that the company was providing an improved model. The CS540 base unit is smaller, has more visible indicator lights, improved switches, and is compatible with the handset lifter I already owned. So I ordered it from Amazon and two days later was again enjoying clear sound and amazing range. I work from home and often roam during phone conferences (more coffee, fetch files, etc.). My old Plantronics headset let me get a few rooms away before losing the signal, but the new CS540 lets me get to every room in my 2 story house with no noticeable loss of signal. The CS540 can be used over-the-ear or over-the-head, but I find the lightweight earpiece to work very well resting on my ear. The mic boom is slightly adjustable toward my mouth, and very adjustable up and down. So finding a comfortable position is easier than with the older model. It's easy to forget that I am wearing it. The CS540 sound quality adjustment switches are much easier to understand and use than the older model. A call to the Plantronics 1-800 number is a quick way to get the settings correct, followed by a call to someone willing to answer your questions about "how does this sound?" In my case the switches required only minimal adjustment from the factory settings. The person I called said she could not tell I was speaking over a headset. And I could hear her as if I were listening on the phone's regular handset. The CS540 is a very well made device. My only minor complaint is the lack of printed instruction manual. The unit comes with a multi-language foldout that is adequate for the initial connection to a desk phone, but it doesn't clearly explain other features such as indicator lights, headband attachment, advanced setup switches, etc. A more complete manual is available online, but I saw what seems to be a few errors related to the advanced switches (for wide-narrow band radio settings, and headset pairing). Despite the errors, I was able to figure it out well enough such that I spent no more than 10 minutes from the time I opened the box to when I was all done with installation and setup. If you spend a lot of time on conference calls I can recommend the CS540 as well worth the extra cost. I've used many other headsets, both wired and wireless, and also Bluetooth, and none of them come close to the quality of Plantronics products. Also: don't skip the automatic handset lifter. It's a clunky looking gadget but it works very well.

Awesome headset. Works great!
I purchased this headset for me to use at work. Part of my job is to do technical webinars, demonstrations, and technical support. I am on the phone all day, every day and needed an awesome headset that had good audio for both microphone and speaker along with long battery life. This headset is all of those things. I have never had the battery go out on me yet. It also charges very quickly. I also got this headset because it the headband is optional. I wear it just over my ear without the headband (the headbands start to hurt the top of my head). It comes with several options regarding earbuds and over-ear connections. I found a combination that works for me. It fits snugly, does not move, and can be adjusted to be closer or further away from your face. The range has been amazing too. Some of my phone calls can become quite lengthy and it is nice to be able to walk around my office, fill my coffee etc. without feeling chained to your desk. I have used this for a couple of weeks now and have never once had a complaint from the the person on the other end about the sound. This is a great headset. I have no complaints about it. It was easy to setup and works great.

The original headset lasted several years and still works great! With newer IP phones
We used an older Plantronics headset with an analog phone. Plantronics generally makes a quality product. The original headset lasted several years and still works great! With newer IP phones, we had to purchase a different headset. The CS540 headsets were recommended by colleagues. The headset is easy enough to setup but requires an additional cable (APC-41), which is a tad pricey. I purchased 4 headsets and one was defective. The headset also requires a setting change on CISCO IP phones, which is a hassle if the telecom equipment is controlled by someone else. This is a wireless headset and just like any wireless audio there are hiccups in the sound quality. However, generally the sound quality is good. The base charges the headset and holds the headset in place. There are lights on the base which tell you when the headset is charging and when it is connected. The headset requires one finger operation to engage and disengage a call. I give this item a 4 out of 5 stars because of the additional cable. Plantronics should have included the cable.

Good product, highly recommended
I recently bought this to complement my Obihai 1062. It works great, good sound quality (you need to set it to wideband by adjusting one of the switches in the CS540). Microphone volume was too low on the "1" setting but also you can modify this and I hear no complains from the people I talk with by the phone, as I used to by just using the speakerphone in my Obihai. This allows you greater mobility while in the office. Great for streching your legs and make your long working days more bearable. I normally connect my personal phone by bluetooth to the Obi and use the platronics with it, better than my other bluetooth headset. The headset is light and confortable. My product came with the headset attachment included, no need to buy a spare one. I don't have issues with battery life, but if this is a concern to you there are other more expensive products with a few more hours. Overal a good product, hightly recommended.

Move Along. Too Many Flaws for Daily Use.
I've used this headset for a year now, plenty enough time to give it an honest review. I'm currently looking for a replacement. I love the style of this product, but thats about where it stops. The ear clip is small and brittle. They give you two, but neither fit well. I did away with them within the first two weeks. The rubber ear pieces (which can be used without the clip and come in many sizes) stay in the ear ok, but they don't stay connected to the device well, so eventually (and semi-frequently) it will fall out and you'll be left with the rubber piece still in your ear and the device on the ground. The volume on the device is also too finicky. There are two adjustments - general volume, and mic/speaker gain (on the base). Most of the volume options are far too quiet. Once you finally get a good volume in the ear, the mic will feedback. It also distorts very easily and I've just accepted that calls will be uncomfortably quiet. I've put up with all of this until the most recent issue, though. After about 15 mins of use the mic will randomly start feeding back in your ear. The callers on the other end can hear it too. If you can push through that, eventually the ear piece will shut off and start screeching. The only way to fix it to put it back on the charger for a few minutes. It didn't do this at first, but now its almost unusable. The whole reason you want this thing is for calls LONGER than 15 mins. I typically like Plantronics products, but I can't recommend this one. It's a great looking device with far too many flaws.

Great Wireless Connection
This works great !! It charges quickly, it last for hours, it is comfortable around the ear, the voice is clear on both ends, no noise or interference. I use this at work. I spend a lot of time on phone/conference calls. It was worth every penny to be wireless and be able to move around or walk a way from my desk if need be. You can stay connected for a good distance. When it was delivered I could not get it to charge, one of the contacts in the base was pushed down to far so it could not connect with the ear piece. Amazon sent me a brand new one and when it arrived I sent the other one back. It was the easiest process and best experience I have ever had with an Online return. It is exactly as described and works great for me. I have no negatives about this product.

Will save your neck
I bought this because I was holding the phone receiver with my head and shoulder all day (horrible I know) and I just couldn't take it anymore, I had to go to the chiropractor I was in so much pain and that's when I caved and bought a headset. I love that this one is wireless, and it did live up to it's claims of quality. I do have one complaint which knocked two stars off the review: the dang thing is SO finnicky with it's connection. Once it does connect, it works fine and it usually will work for the rest of the day UNLESS I accidentally bump the microphone with my hand or take it off, then I have to wiggle it around until it starts working again. The benefit far outweighs the trouble though, if you're having neck or posture issues don't worry too much about getting the wrong thing, just get a head set seriously you'll thank yourself later.
