sulli's Journal: Ask the faithful remnant: Bluetooth headsets for concalls?

So I am on a lot of conference calls. Like 3-4 per day. And I often take these calls from a mobile phone (Treo) with a bluetooth headset. (Current one is from Plantronics, nothing fancy.)

Is there a headset that someone has built that is specifically optimized for conference calls? By which I mean, one with a one button or one motion mute? With the treo I have to use an on screen button to mute, which is a big pain when walking or driving. (Of course the headset has some weird option involving holding down a button or something, but that does not work if I can't look at it.)

Any ideas?
