Dear wonderfalls and SingDanceRunLife, that would be excellent if I could find those. But I do not know what words to use, to hunt for them. Do either of you know how to find such a pair? The cell phone headset I lost cost $104.00. I have already ordered another pair but could cancel if a dual function set turns up that is less than $300.00. I talked to the dealer about noise cancelling phones and they said I want one that is 100% noise cancellation, that the ones they carry only do 80%. PS Turns out I can't go on this trip after all. The cost of changing the date on the ticket is prohibitive.
