OK.. this is interesting. I have my Samsung headphones on right now, watching The Today Show (video podcast feed of the show from NBC) here at work. I decided to get up to go to the break room on the other side of the building to get some ice for my drink (I sit on one extreme end, break room is on the other side of the building I work in (tallest building in Hartford, CT, in fact). I leave my Galaxy Tab in my cubicle and began walking with my cup--no loss of audio. I keep stridently walking and walking and get to the break room where it FINALLY began cracking up a little. WOW! That's easily far beyond the 30 feet that Bluetooth is supposed to be rated for. Without measuring, I think it's closer to 100 feet away. I'm not sure if it's to the Tab's credit, or the Samsung headphones, or both. Once I finish charging up my Motorola headphones, I'll have to try the same experiment to see if there's a difference.
