Just picked these up at Best Buy, and they work amazingly well with the Droid!
My previous myTouch, with another bluetooth wireless headphone set, would skip about every minute or 90 seconds, which greatly diminished the enjoyment of wireless listening.
Not sure if it's improvements to the Droid's bluetooth A2DP coding or the Jabra Halo's, but these things work GREAT!
Sound is excellent, NO skip at all after over an hour of listening, and they are lightweight and very comfortable to wear.
They are not the smallest headsets, but they do fold to reduce the overall size. They are also not "in ear", but place the speakers on top of your ears. They are, however, light, have a velvet type padding on the entire inside of the headset, and again, sound great!
They come with a short USB cable to charge from your computer, a long wired charging cord to plug into an outlet if you'd prefer to charge from a wall socket, along with another cord to allow you to use them "wired"... perhaps if the battery goes dead? Not really sure why you'd want to use a cord on a wireless pair of headphones, but again, perhaps it's so if your headphones are out of juice, your music pleasure doesn't need to stop!
If you've held off getting wireless ears, thinking the technology "isn't quite there yet"... check these out!
