Jabra Supreme Bluetooth headset $86.70
It has active noise cancellation and flipping the arm turns it on/off. It's also on ear rather than in ear. Pretty big so you look like mission control, but I think with any of these you look a bit of a dill.
Lots of features like noise cancelling microphones, music streaming, on phone screen battery level display.
Also available here if you want local support (around $103)
Others I considered were:
Sennheiser VMX 100 ($85 ebay UK)
Planetronics Voyager Pro HD ($96 ebay US)
Jawbone Era ($50 refurb, $82 new ebay US)
This one has active noise cancelling too.
