The WMD will stream up to 8 hours on a charge. Maybe not long enough for a 14-16 hour flight to Europe or Austrailia from the States, but certainly good enough for the majority of people’s needs. And as Miikerman said, it is plenty small to fit in a pocket; 2.6" x 2.6" x 0.54". The Wireless Stick is its baby brother.
I use it frequently with my iPhone 5S & JayBird Bluebuds Sport wireless bluetooth earphones when going on walks. I don’t have to waste storage space on my phone with music files. I only wish the app for it had an EQ or would work with the iPhone EQ or other 3rd-party ones. I generally listen to my music with a flat repsonse, but there are times when a little boost of treble or bass would be nice with certain songs.
I’ve also used it to stream old TV shows & movies ripped from DVD’s to my iPad while flying. I think it’s great.
