Short answer: the JBL Go 4. It ranks #25 of 47 small speakers by sound quality, rated 3.2/5, at $49.95; the Noxgear 39g ranks #46, rated 2.2/5, and costs $69.95, so there is little reason to consider the other one.
The case for the JBL Go 4: A little more bass than the Go 3 and they fixed the strange mids peak. The tradeoff: Not much bass at all, especially with electronic/bass-heavy tracks pushed past ~50% volume.
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 JBL Go 4. 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.
Battery life favors the Noxgear 39g: rated for 15 hours against 7 hours for the JBL Go 4.

Newer model: the JBL Go 5, rated 3.2/5.
Pros: A little more bass than the Go 3 and they fixed the strange mids peak. Measured bass extension of ~82Hz (-10dB).
Cons: Not much bass at all, especially with electronic/bass-heavy tracks pushed past ~50% volume. Midrange can sound grainy and treble a bit sizzly; loses clarity at higher volumes.

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.
