This speaker is a collaboration that Burton did with Braven. It was made during the early days of bluetooth speakers, and as such is pretty basic. It has four buttons: Power, Play, Up, Down. I have used it almost every day since the day I bought it (over 7 years ago), and it is still going strong! It has been with me on three different continents, so it is only fitting that I have it with me now. It holds a charge for several days, and can be used as a backup phone charger if needed. The sound is pretty decent for its size, and it is basically bulletproof.
