This is not meant to bash Seidio, but I guess it does. I purchased their 2in1 headset for my Treo 650. The behind the head style one. It sucked. The idea and concept is great, but where the mic and the volume knob are, there is a short. Happened within a month or so of purchasing the item. I read a thread earlier today on Treocentral where a bunch of people have purchased crap quality items from these people. Doubtful that I would purchase another of their products.

Good luck to you though.
