Typically, my conference calls occur in front of a laptop, which I may or may not be sharing over the web with those on my call. So a USB connection is fine (it is longer than my arms, which remain connected to my laptop keyboard).
I used the Everyman Freetalk this week -- it worked great! Thanks Kelly!
Of course, now I have experienced the quality of the sound from this headset, I wonder about a wireless version for occasions where I am NOT connected to a keyboard. But currently I don't use Skype. Maybe it is time to revisit my base technology for phone calls.
