Short answer: the Marshall Willen II. It ranks #11 of 62 small speakers by sound quality, rated 4.0/5, at $129.99. The Noxgear 0.1 lbs (39 g) ranks #61, rated 2.2/5, at $69.95, $60.04 cheaper, which does not close the gap in sound quality.
The Marshall Willen II is the better-sounding, deeper-bass option. A tiny waterproof strap on speaker with balanced sound, a long battery, and app EQ that clips easily onto a bag. Its bass reaches about 70Hz 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 catch: Not that deep of bass.
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 Marshall Willen II at 0.8 lbs (360 g). Watch for: It sounds worse than a clock radio with the worst bass of any speaker.
Buy the Marshall Willen II. It is rated higher for sound quality, and saving $60.04 with the Noxgear 0.1 lbs (39 g) does not make up for the sound-quality gap.
