Plantronics continues the tradition of its CS line of wireless headsets with the CS540 convertible wireless headset. While this headset is similar to the long standing CS55, it's quite different in design and function.

The CS540 offers a new and improved range of up to 350 feet. While still not the longest available range in wireless headsets, it's definitely a nice increase over the 300 foot CS55. As with all wireless headsets, this wireless range offers the ability to be up and about, grabbing files or coffee, or even stepping outside, all while staying on the phone and working 100% hands-free. Throw in the HL10 handset lifter (included in the Professional Bundle) and you can even answer and end calls while away from your phone.

In addition to the improved range, the CS540 also allows you to pair up to three additional CS Series or Savi headsets to the same base for conference calls. This means no more fiddling with hold and transfer buttons, conference call numbers or the dreaded conferencer.

The CS540 is definitely a step up from the CS55 and worth checking out. Back to top

The headset ordered did not meet the user's needs. Josh Mitchell was extremely helpful in the return and reorder. Josh made it so effortless it left me question, how was this so easy?

Ease of use
Customer Rating:
The over the ear set-up is not practical for usage where I have to take the earpiece on and off. The phone is nearly to voicemail by the time I am two handing it to get into my ear. The rubber tip that fits into the ear comes off easily, I have already lost one. When I use the over the head set-up, it goes on quickly but I can't adjust it so it stays on my head without sliding off. Still much better than not having one and I am adapting. Might be a good choice for someone who keeps the earpierce in all the time.

Very reliable headset

We use these headsets throughout our call center (20+ agents) and they work flawlessly. On a full charge, they easily last 10+ hours standby time and over 4 hours of talk time.

Bad battery?
Customer Rating:
Mine headset charged for 3 days I have been using it for 2 days now and everyday ~9 hrs into the day the low battery beep starts. My old Plantronics lasted much longer on one charge. I know I had used it on a 20 hr shift and never beeped once. I liked the old head hear that went around the back of the head and do not like them to hand from my ears. I work 12 hr shifts and they begin to dig into my ear becomes painful.

Very impressed!
Customer Rating:
I am very impressed with this headset. I ordered it because I was looking for a headset that you could just wear over your ear. I had another headset before that would not fit securely over the ear before and it was frustrating, so I was very excited when this one fit nicely. It is an all around wonderful product. Thank you Plantronics!!

Customer Rating:
This device is very comfortable and there is very little movement if any. The rubber ear piece fits snuggly in the outter canal making it easy to hear the caller clearly. I love this device. Go Plantronics!!

We are really enjoying our new headset CS540. Our only complaint is it's difficult getting the rubber earpiece into your ear and locked in. Once it's there, it's awesome!

Excellent and superior replacement for the CS50
Customer Rating:
I ordered these because I've been having problems with some Plantronics CS50 units working with my company's Cisco 7942, 7962, etc. phones, which all have a headset jack and button that should mean you don't need a lifter to use the headset.

Unfortunately, while some CS50's would work fine with these phones, I'd have other units, exactly the same, configured exactly the same that wouldn't work with the headset jacks on these phones, even though other units would. This inconsistent behavior had me looking for something better.

I appear to have found that replacement. I've so far ordered two of these units and both work wonderfully with the headset jacks/buttons on all the phones I've tested them with so far (4 different phones of various models). The units are more compact and better-looking than the CS50s, sound is excellent, and once I figured out which setting to use on the slider at the bottom of the units, setting them up has been a breeze.

All in all, a great headset if you use phones with dedicated headset connections. And if you're like me, a Plantronics fan, they're a great choice.

I have been using this headset for almost 1 year and I love it! Very lite to have over the ear, easy to put on and have never had a problem with the battery running low. Have used different headsets in the past and I have to say this is my favorite so far.

I have been using this headset for about 1 month and love it. It was easy to set up and I have never had an issue with the battery running low. I put it back on the charger at lunch time. I work from home, but for a call center and it was compatible with my Inter-Tel Model 8662 Phone. I've used it over the ear and over the head and both work fine. I did purchase the optional Plantronics HL10 Automated Handset Lifter, that too was easy to set up and it works PERFECTLY!! I HIGHLY recommend this product.

I enjoy using this wireless headset - it is NOT a user friendly ear piece, however. The clear insert that fits in the ear falls off the headset frequently and the piece that goes around the ear does not fit well.
