I have one... I bought one for my assistant and one for my brother in-law. Half of the advisors in my office (about 25 total) use Plantronics headsets and they all work great. This one in particular is very 'stylish' but the older model works great too. The handset lifter is nice as you can answer or hang up a call up to 300' a away. If you need to multi-task and must pace when you talk, this is a must.
I used Plantronics for years. This is the 3rd one I use and the previous that I used was different brand. So far, I like Platonics the most not only the price but also the style. The only complaint so far I have is. I need to switch from earset to handset when I need to page the whole office. Otherwise, it is like the maximum noise and blow the speaker when using that.
I have owned numerous headsets and used them in the office. I need more than 12' of reliable range so the bluetooth headsets are not an option. The Plantronics CS70N is well made and has held up well with good battery life over the 3 months that I have used it so far. The only improvement that I would like to see is a better fitting over the ear mount. That said, it is comfortable and can be worn all day without a problem. I would order this headset again in a heartbeat.
The CS70N™ gives you the best of both worlds in one professional wireless headset: premium audio performance and sleek, comfortable styling. Featuring a top-of-the-line, Noise-Canceling microphone for clear speech even in environments with distracting background noise, the CS70N is perfect for a wide variety of users and business environments. A stylized, lightweight behind-the-ear design is not only discreet, it is comfortable enough to be worn all day. A superior microphone and earpiece create a high-performance headset yielding great results for both traditional phone lines and IP telephony systems. The CS70N offers wireless freedom with no compromises. Includes the Plantronics HL10 handset lifter for remote call answer/end capability.
