Excerpt: The photos and information did not give me the information as to what the end of the cord was like - if it would attach to my system or not, so ended up ordering what looked right and ended up not working.
Summary: The employees love this headset. Easy to function and they can walk around the office and down the hall past 6 other offices and still be able to function the phone. Their neck aches have diminished. Works great with the NEC system.
Summary: Plantronics makes a great headset. I happen to get a bad one, but would still endorse this company and product. I purchased another one on Ebay and was well pleased with the service of the unit. Very dependable.
Summary: This headset was simple to set up...even for the technologically challenged. It took a bit of time to get the settings adjusted perfectly for all parties, and to rearrage the desk so the phone is not next to the computer. The computer causes interference, and the handbook warns of this; they need to be at least 12 inches apart. Over all, it is a great buy! Two days after we bought this, we received a coupon in the mail for this EXACT headset at double the price!
