Short answer: the Tribit Stormbox Blast. The ZZA K8 is completely insane value for the money, but its very V curve frequency response can be harsh in the treble range. The Blast is the better balanced of the two and competes with some Party-size speakers despite its size, though it dips at 5.5kHz and loses a little detail.
Buy the Tribit Stormbox Blast. It is rated higher for sound quality; the ZZA K8 is no longer sold new.
