Short answer: the Tribit Stormbox Blast. The Onyx Studio 8 is warm with boosted bass but not as loud as others. The Blast is amazing given its size, competes with some Party class speakers and reaches bass almost as deep as a Partybox 100, at the cost of a bit of detail versus top ranked speakers and a dip at 5.5kHz.
Buy the Tribit Stormbox Blast. It is rated higher for sound quality; the Harman Kardon Onyx Studio 8 is no longer sold new.
There is a real battery-life gap here: the Tribit Stormbox Blast is rated for 30 hours, the Harman Kardon Onyx Studio 8 only 8 hours.
There is a real gap in water resistance: the Tribit Stormbox Blast at IPX7 (brief submersion) against the Harman Kardon Onyx Studio 8, which has no water resistance.

The Two Speakers In Full
Tribit Stormbox Blast: $179.99 Amazon eBay
Newer model: the Tribit Stormbox Blast 2, ranked lower, rated 3.8/5.
Pros: Amazing speaker given its size, competes well with some speakers in the Party size class, bass almost as deep as a Partybox 100. Quite neutral in the default and xbass modes, but try Oluv’s EQ or Alan Ross’s EQ for a slightly more neutral sound. Oluv has mentioned v3.5 now uses his EQ as the defaults and sounds extremely good. 2 different light modes or can be turned off. Measured bass extension of 43Hz (-10dB).
Cons: Lacks a bit of detail compared to the top ranked speakers in other size categories, dip at 5.5kHz. Without the above EQ this speaker would rank around #4 in the rankings. The curved underside of the handle makes it a little harder to grip and can be uncomfortable to carry long distances.
