I will soon inherit a treo 650 and am looking to upgrade my headset options with the bluetooth includeed. I've done some searching and it seems that there aren't many options for stereo IN EAR headphones. I am not a big fan of all the headsets that sit on top of your ear. Plus i have really good in ear headphones already that i have been using for awhile that I wouldnt like to give up. So what I am really asking is what is the best for connecting to the treo 650 in stereo sound while still being able to use my own headphones and also answer calls? I have seen some of the products have those little clips that attach to your shirt, but not many allow for switching different headphones. Thanks in advance!
