Short answer: the Sony SRS-XB100, though neither ranks well in its class. It ranks #35 of 49 small speakers by sound quality, rated 2.9/5, at $63; the Noxgear 39g ranks #48, rated 2.2/5, and costs $69.95, which makes this an easy call rather than a real tradeoff. Both are rated below 3.0/5 among the 49 small speakers; for better sound, the Tribit Stormbox Micro 2 ranks #1 at $49.99.
Why pick the Sony SRS-XB100: Long real-world battery life (~17 hours in testing). Watch for: Not much bass.
Why pick the Noxgear 39g: Magnetic clip attaches through a shirt/jacket without pins. Watch for: It sounds worse than a clock radio with the worst bass of any speaker.
Buy the Sony SRS-XB100. It is rated higher for sound quality than the Noxgear 39g and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

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.

Noxgear 39g: $69.95 Amazon eBay
Pros: Magnetic clip attaches through a shirt/jacket without pins. Blue safety light for visibility when running in low light. It’s only 39g of weight. ~15 hour battery life. Measured bass extension of ~300Hz (-10dB).
Cons: It sounds worse than a clock radio with the worst bass of any speaker. It’s a huge compromise in sound for the small weight.
