After many attempts to get the headsets set up we were finally able to do so. Thanks to Rebecca for helping me through the entire process. Also enjoyed the tootsie rolls with each box that was shipped! What a great touch!!

Disappointed in the failure of the cord.
My experience in replacing the cord was very good.
