I had the Logitech Wireless Headphones for PC and the headband broke, so they're sending me new FreePulse Wireless Headphones. They're designed to work with the BT dongle they come with, but I'm curious if they can be used directly with a Treo and SAG. I'll be ditching my 650 for a 755p soon and it'd be great if I can use these headphones without having to use the dongle. I searched around and found a few threads mentioning the headphones, but nothing specific about whether they work or not with SAG and not using the dongle. Has anyone gotten the headphones to work this way?
