Yesterday, Bluetooth SIG and its members hosted a holiday preview at Central Park's Tavern on the Green, showing off a plethora of Bluetooth devices ranging from phones and smartphones to headsets to audio devices. My colleague PJ was quite excited about the Motorola H680, which he hadn't seen before. I liked how teeny and discreet Bluetooth headsets are becoming (like the Motorola H9 at left), as well as the sound quality improvements in wireless speakers and headphones. Check out images of what all the Bluetooth we saw, including a cool GPS add-on for smartphones, after the jump.
