Short answer: the Noxgear 39g, if you are buying new, though neither ranks well in its class. The Harman Kardon Neo ranks higher than it (#45 vs #48 of 49 small speakers, 2.3/5 vs 2.2/5) but is discontinued, so only consider it used; the Noxgear 39g is still sold new at $69.95. 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.
The case for the Harman Kardon Neo: Harman Kardon Neo uses 1.6” (41mm) full-range driver. The catch: Bass is limited by its 105Hz specification.
Why pick the Noxgear 39g: Magnetic clip attaches through a shirt/jacket without pins. The tradeoff: It sounds worse than a clock radio with the worst bass of any speaker.
Buy the Noxgear 39g, since the Harman Kardon Neo is discontinued and only worth hunting down used.
If water resistance matters to you, the Noxgear 39g at IPX7 (brief submersion) holds up far better than the Harman Kardon Neo at no water resistance.

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.
