I was given a Voice Star headset for my cordless phone as a gift. I use it on my cordless phone all the time and have actually become quite addicted to it. It's great because you can carry the phone ion your pocket or on a clip on your belt and have your hands-free while you talk. The ear pieces are made of very cushy, soft material, and fit snuggly against your ear. The mouthpiece is adjustable, and moves easily about. It fits snugly on my head without being too loose or too tight. I can hear almost perfectly on it, sound comes through loud and clear, and I am heard on the other end very clearly also. It could be a little better with background noise cancellation, but other than that, this Voice Star headset has been a hit. It has lasted quite a long time and has not shown any signs of wear and tear. A great product and a must-have in today's multi-tasking world.
