The Crew Likes Them!
I ordered around 10 of these and each one is in use and doing well. My crew really enjoys not having to pick up the phone to answer a call or to make a call. These headsets are great and easy to set up and use. The sound quality is wonderful and the ear piece is nice and comfortable. Helpful Hint - Before you buy, make sure that it is compatible with your phone(s). I made that mistake on the first set I ordered and and to return.

Bought for work. Worked well for its purpose for specific busy times. Wireless would have been awesome, but not from my out of my pocket.
