Short answer: the Soundcore Select 4 Go. It ranks #23 of 47 small speakers by sound quality, rated 3.3/5, at $22.99; the Noxgear 39g ranks #46, rated 2.2/5, and costs $69.95, which makes this an easy call rather than a real tradeoff.
The case for the Soundcore Select 4 Go: Quite inexpensive for what you get. Watch for: Not as deep of bass as higher ranked speakers.
The case for 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 Soundcore Select 4 Go. It is rated higher for sound quality than the Noxgear 39g and costs less, so only choose the other one for a particular feature it does better.

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.
