Short answer: the Klipsch Austin. It ranks #15 of 62 small speakers by sound quality, rated 3.7/5, at $54.95; 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 Klipsch Austin is the better-sounding, deeper-bass choice. A rugged waterproof mini speaker with dual passive radiators, a metal grille, and stereo pairing with a second unit. Its bass reaches about 70Hz before falling 10dB, against 300Hz for the Noxgear 0.1 lbs (39 g). It links with other speakers (Broadcast Mode), which the Noxgear 0.1 lbs (39 g) cannot. Watch for: Not as deep bass as higher ranked speakers.
The Noxgear 0.1 lbs (39 g) is the lighter pick. 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 Klipsch Austin at 0.9 lbs (397 g). The catch: It sounds worse than a clock radio with the worst bass of any speaker.
Buy the Klipsch Austin. 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.
