This has got to be one of the greatest values out there.  I only paid $42 and got free shipping, what a deal.  This headset works outside in the wind.  My previous headset cost more, would not work in the slightest breeze, and it also fell apart after 2 months.  The Plantronics is obviously superior to many bluetooths costing twice as much.  The stiff on/off button is not a problem once you get used to it.
