Quality and Use: 3 people in our office have been using these Plantronics headsets for about 4 years now and they have worked great. We have a service and repair business with very busy phones so we are constantly on the telephone taking orders and talking to customers. We can walk about 300 feet away from the base without any problem including outside the office. You may be able to go farther or be limited to shorter distances but I believe it would depend on the construction of your building. There are several buttons on the headset and one I find very useful which is a MUTE button. I can talk privately for a moment if needed without the caller ever knowing and there is no need to put them on hold. The other buttons are for volume and answering the call. One more great feature to point out is that you can move about the office to get files, make copies or faxes and even work from another desk without putting someone on hold.

As far as battery life goes, when left to charge overnight the unit will last all day with busy phones without any need a recharge. We have never replaced the batteries in the units so they seem to hold up well over time. I did purchase a replacement for a unit that ended up cracked where the arm that goes around your head connects to the earpiece but I think 4 years of use is acceptable for the cost.

Ergonomics: I was getting a sore neck and shoulder from holding a standard phone with my chin and shoulder before trying one of these but the pain went away after a month or so of strictly using the headset. If you suffer from this kind of pain I think this can really help.

A few observations:

o The Plantronics CS351N is a mono, over-the-head, wireless model with noise-canceling microphone (not the clear tube type)

o My reference is a top-of-the-line corded mono, over-the-head, corded Plantronics with noise canceling microphone that I bought for $139 8-10 years ago that is absolutely perfect in the performance and comfort departments (except for, well, the cord).

o I have the base station plugged into the headset port on the back of a Cisco 7961. No handset lifter since I work near the phone and have little need to answer the phone remotely. There is an auxiliary phone jack on the base station, so my old corded model is plugged in there and you can switch back and forth at will. The base station has about four inches of separation from the left/handset side of the 7961.

o It took Plantronics tech support to get the sound quality to an acceptable level. Feedback I get is "pretty good", "not quite as good as the corded headset but close", but also "tinny" (compared to corded). Overall, I'm in the "get used to it phase." Depending on further feedback, I might use the corded model if doing WebEx presentations to a non-native-English speaking audience... any edge to improve comprehension.

o Current settings are:

-- 4 on the Configuration Dial

-- B on the raw mic setting

-- a few pushes up on the fine mic setting.

-- 4 on the raw earpiece sound

Out of the box, there was a nasty echo for the person on the other end and the sound was tinny on my end. Tech service (out of Tijuana) had a more organized way to get it dialed in. I was two clicks from sending it back, so good on them.

o In general, the industrial design is a bit confusing--the raw sound setting is next to the fine mic setti...
