Short answer: the Sony SRS-XB100 for battery life, the HK Esquire Mini 2 for its extra jobs, though neither ranks well in its class. The Sony lasted about 17 hours in testing but has not much bass. The Esquire Mini 2 doubles as a hands-free speakerphone and a USB power bank, yet it has a huge lack of bass. Both are rated below 3.0/5 among the 49 small speakers, and the Tribit Stormbox Micro 2, ranked #1 at $49.99, is a better place to start if sound quality matters.
Buy the Sony SRS-XB100. It is rated higher for sound quality and still sold new, while the Harman Kardon Esquire Mini 2 is discontinued.
If battery life is a priority, the Sony SRS-XB100 is rated for 16 hours versus 10 hours for the Harman Kardon Esquire Mini 2.
There is a real gap in water resistance: the Sony SRS-XB100 at IP67 (brief submersion) against the Harman Kardon Esquire Mini 2, which has no water resistance.

Sony SRS-XB100: $63.00 Amazon eBay
Older models: the Sony SRS-XB13 (ranked lower, rated 2.8/5) and the Sony SRS-XB12 (ranked lower, rated 2.5/5).
Pros: Long real-world battery life (~17 hours in testing). IP67 rated and pocketable at 267g, with a clip for bags/gear. Can stereo-pair two units.
Cons: Not much bass. Seems pretty much the same as the XB13, maybe a teeny bit deeper bass and a little less muddy.
