Short answer: the Sony SRS-XB100, though neither ranks well in its class. It ranks #43 of 63 small speakers by sound quality (rated 2.9/5) at $63 and is still sold new; the Sony SRS-XB13 ranks #45 (rated 2.8/5) and is discontinued, so it is only an option used. Both are rated below 3.0/5 among the 63 small speakers; for better sound, the Tribit Stormbox Micro 2 ranks #1 at $35.39.
What the Sony SRS-XB100 does well: A pocketable waterproof speaker with a long real world battery, a clip for bags, and stereo pairing. The tradeoff: Not much bass.
The case for the Sony SRS-XB13: A waterproof pocket speaker with a long battery, a detachable strap for bags or bikes, and USB-C charging. The tradeoff: Bass is limited by its 88Hz specification.
