I picked up one of this for my motorcycle trips based on some reviews. I have to say it is an excellent little speaker and will be a great thing for camping and travel this summerhttp://www.philips.ca/c/cell-phone-accessories/soundshooter-bluetooth-orange-sbt30org_00/prd/en/
Bought mine through Apple.ca for $49 ... hands free calling too that interupts the music at the touch of a button. I got black just to really bug the boarder guards and the airport xray !!
And yeah, it is about the size of a grenade ... lol.
