We own the Jabra BT200, Logitech (forgot the model, but it's like a
claw), Fellowes Blueglove, and just got the Scala500. We also have
several BT phones.
There is no combination of phone and BT headset that will work
satisfactorily more than 6-8'. No combination will work "through" the
body. That is, if the phone is on the hip and the headset in the ear, no
luck - the phone must be in a shirt pocket or handheld away from the body.
What did we miss? Is BT a joke?
