Short answer: the Tribit Stormbox Micro 2. It ranks #1 of 62 small speakers by sound quality, rated 4.5/5, at $35.39; the Noxgear 0.1 lbs (39 g) ranks #61, rated 2.2/5, and costs $69.95, which makes this an easy call rather than a real tradeoff.
The Tribit Stormbox Micro 2 is the better-sounding, deeper-bass choice. An excellent sounding small speaker, with surprisingly deep bass for its size and a strap that holds it on a bike or backpack. Its bass reaches about 65Hz before falling 10dB, against 300Hz for the Noxgear 0.1 lbs (39 g). It has an adjustable EQ, which the Noxgear 0.1 lbs (39 g) lacks. The tradeoff: Finicky phone charging, which doesn’t usually work.
The Noxgear 0.1 lbs (39 g) is the lighter option. An extremely light speaker that clips magnetically to a shirt, with a safety light for runners in low light. At 0.1 lbs (39 g) it weighs much less than the Tribit Stormbox Micro 2 at 0.7 lbs (317 g). Watch for: It sounds worse than a clock radio with the worst bass of any speaker.
Buy the Tribit Stormbox Micro 2. 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.
