Short answer: the JBL Go 3. It ranks #31 of 62 small speakers by sound quality, rated 3.2/5, at $35.95; the Noxgear 0.1 lbs (39 g) ranks #61, rated 2.2/5, and costs $69.95, so there is not much of a tradeoff to weigh.
The JBL Go 3 is the better-sounding, deeper-bass choice. A pocket sized waterproof speaker with a rope loop for clipping to a bag. Its bass reaches about 87Hz before falling 10dB, against 300Hz for the Noxgear 0.1 lbs (39 g). The catch: Not much bass at all, strange mids peak.
The Noxgear 0.1 lbs (39 g) is the longer-running, lighter pick. An extremely light speaker that clips magnetically to a shirt, with a safety light for runners in low light. It is rated for 15 hours of battery against 5 for the JBL Go 3. At 0.1 lbs (39 g) it weighs much less than the JBL Go 3 at 0.5 lbs (209 g). Watch for: It sounds worse than a clock radio with the worst bass of any speaker.
Buy the JBL Go 3. It is rated higher for sound quality than the Noxgear 0.1 lbs (39 g) and costs less, which makes it the one to get unless you need something the other one does better.
