Short answer: the Sony SRS-XB13 for battery life, the Harman Kardon Esquire Mini 2 for its extra roles, though neither ranks well in its class. The Sony runs around 16 hours and costs $38.51 less, 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, so if sound quality matters, consider the Tribit Stormbox Micro 2 instead, ranked #1 at $49.99.
Buy the Sony SRS-XB13 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the Tribit Stormbox Micro 2 instead.
There is a real gap in water resistance: the Sony SRS-XB13 at IP67 (brief submersion) against the Harman Kardon Esquire Mini 2, which has no water resistance.

Newer model: the Sony SRS-XB100, ranked higher, rated 2.9/5.
Pros: Sony SRS-XB13 uses 46mm. Its 255 g, claimed 16 hours (Manufacturer specified) battery life, IP67 protection, up to 88dB and mono playback make it a practical option for its intended room or portable use. A removable strap hangs it from a bag or bike. Measured bass extension of 88Hz (-10dB).
Cons: Bass is limited by its 88Hz specification. There is no companion app. No EQ adjustment. Not much bass, and the sound is muddy. Discontinued.
