I ended up buying the Cambridge Oontz Angle 3 to have for a small portable speaker. It's not bad considering the size (really small), but it is not even close to HiFi. However, for less than thirty dollars with free shipping from Amazon, it's a great deal for a super portable.
Interestingly, my neighbor brought over his bluetooth speaker for a little get together this evening that included a lively game of music roulette. It turned out to be the Libratone. It's a nice speaker. Sounds way better and bigger than the little Oontz. I would definately consider buying one. It's portable enough since it has a small footprint and a nice carry strap. And it puts out enough sound to make it useful for small get togethers. It's the best combination of functionality, portability and sound that I've heard so far.
