Rated 5 out of 5 by from Volume button shorts out audioI've had this for about a year. Worked great - good sound, battery (for my purposes). Then, about 3 months ago the mute button stopped working correctly - when I press it in, it mutes and un-mutes immediately - didn't do that before - I have to press it 3 or 4 times for it to work properly. Also, any time I want to adjust the volume now, it shorts out the audio/mic for about 5-10 seconds, then comes back on. Not ideal when in the middle of a conference call - especially when hosting it.

Rated 5 out of 5 by from Beats any JabraI tried several headsets before settling on this one. Most were Jabra. They were too heavy and didn't stay on the ear when using the ear hook. This Plantronics version is light enough that the hook always stays attached and stays on my ear. I bought 4. My colleagues also love these. They call quality is crisp. The design is pristine and slender. Used with the hook switch, you can pick up calls with ease while away from your desk. All buttons are easy to find (by touch) and use.

Rated 5 out of 5 by from Good headset / careful with phone firmware updatesI've been using this headset for the last year and a half and I really like it. Easy to use and I almost forget it on my ear when I wear it.But recently, with a firmware update on my Cisco phone, I coudn't hear any "bips" for incoming calls anymore. Had to go back to an previous version of the firmware on the phone and headset was fully operational again.Maybe Cisco should check this problem with firmware updates ?

Rated 5 out of 5 by from nullIn our business it is great to have our hands free while we are on the phone with our customers. We often need to get up to obtain a loan file, or to walk across the office to speak with another colleague while we are on the line. Our new Plantronics CS540's work great for our team, and make us more efficient in our work. We loved the CS line and wanted to stay with Plantronics because it is a local company, and my perception is that Plantronics is the industry standard. I receive catalogs in the mail from other companies, but I don't perceive the same quality that I recurrently have had with Plantronics.

Rated 5 out of 5 by from Helpful toolI bought this item to use where I volunteer. We have several volunteers who answer the phone and need to take down information from callers. Having this ear device has made it easier to use both hands and not have to cradle the phone on our shoulders, which is not healthy. The calls come loud and clear and I like being able to move around and not be hindered by a cord.

Rated 5 out of 5 by from nullI have used this headset at 2 jobs now, both with the HL10 lifter. The headset itself is great. There is a slight learning curve to be able to get it comfortably on your ear within the 3-4 rings before VM picks up. I'm used to it now so I can typically get it on quickly. It is comfortable enough to wear for extended periods of time. Simple controls, clear sound and interchangeable ear pieces make it a somewhat customizable fit. The ear hook with foam is comfortable but the foam padding is kind of cheap. My suggestion for improvement (and a 5th star) would be to improve the ear hook with maybe a rubberized coating or something like that.

Rated 5 out of 5 by from nullMeh. It's ok. I would prefer to have my CS70N back from the dead (the battery was hard wired and trying to solder in a new one was unsuccessful). PROS - Reception range seems to be a little bigger. The volume button is easier to operate. The wrap around ear piece is okay as long as you have the cheap foam cover on it. CONS - I hope you have some desktop room for the base. While at 3.4" (85mm) wide it is on the narrow side of most, the depth is ridiculous. It's about 4"(100mm) for the base and then another 1.25"(30mm) for the wiring plug. Not sure what the designers were thinking. I would rather see some mounting hardware that would allow me to attach it to a phone or monitor or even the wall.

Rated 5 out of 5 by from Constantly troubleshootingSince I've got this headset I had to constantly troubleshoot it - it's fully charge but it turns off in the middle of calls - now the new one is that I can hear the call both, on headset and handset, so what's the point of privacy calls??? I hate this headset, which our company would purchase another brand or product...

Rated 5 out of 5 by from Sleek design, not the easiest to put onI bought this as a replacement for an older over ear wireless headset. It is a design improvement - sleek, elegant. However, the ear piece takes a bit of work to get used to and is not always the most comfortable (the plastic could have been molded a bit better. I do like it a lot though and it functions extremely well.

Rated 5 out of 5 by from CS540I purchased this unit, and with the wires in comes with, I can't set it up in a way that I can pick up the call directrly from the headset. It kind of defeats the purpose of having a Wireless headset. A collegue of mine has the same model, it came with different wires , so that he doesn't have to use the wire with black box attached. Conclusion, he can actually answer a call away from his desk from the headset.

Rated 5 out of 5 by from nullWe’ve currently have Cisco 7961s for our CSRs and will eventually be upgrading to 8841s. We decided to test the phone and headset out on one user. I bought this headset with both the lifter and the EHS cable. The user wanted the EHS cable as they were sick of the lifter; however she didn’t like that you had to press answer on both the headset on the base. My boss and I both tinkered with the settings and looked at guides/instructions and we couldn’t figure out how to change it. The user decided to go back to the lifter. The conversion cable was a little tricky to set up, some models you plug both the conversion cable and the headset cord into the base, and others you plug the headset cord into the conversion cable. The 8841s headsets are too light for the lifter – we had to put Velcro near the mouth piece or it would just slide off! The user loves the headset. Her favorite feature is that she can choose between an over the ear piece or add the headphones band onto it. She also likes that she can have it on/in different ears.

Rated 5 out of 5 by from nullUsing three of these currently and all users love them. They sound great, are comfortable and the coverage/range is amazing. Folks have walked out of the building to their cars and kept phone conversations going. Great product from a long time great company.

Rated 5 out of 5 by from nullA very nice headset with great and accurately advertised range. Get this if you want something non-bluetooth technology so that you get maximum range benefits.

Rated 5 out of 5 by from nulloh my, where do I start? The CS500 series is just awesome! While it lacks multi-device compatibility, it is a rock solid deskphone headset!
