Short answer: the Tribit Stormbox Blast 2 unless price rules. The ZZA K8 is completely insane value for the money but has a very V curve frequency response and can be harsh in the treble range. The Blast 2 has pretty deep bass, though it sounds quite muddy from the boosted lower and upper bass.
Buy the Tribit Stormbox Blast 2. It is rated higher for sound quality; the ZZA K8 is no longer sold new.
