Short answer: the Sony SRS-XB100, though neither ranks well in its class. It ranks #43 of 63 small speakers by sound quality, rated 2.9/5, at $63; the Noxgear 0.1 lbs (39 g) ranks #62, rated 2.2/5, and costs $69.95, which makes this an easy call rather than a real tradeoff. Both are rated below 3.0/5 among the 63 small speakers; for better sound, the Tribit Stormbox Micro 2 ranks #1 at $35.39.
The Sony SRS-XB100 is the better-sounding pick. A pocketable waterproof speaker with a long real world battery, a clip for bags, and stereo pairing. It supports AAC Bluetooth, which the Noxgear 0.1 lbs (39 g) lacks. Watch for: Not much 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 Sony SRS-XB100 at 0.6 lbs (274 g). Watch for: It sounds worse than a clock radio with the worst bass of any speaker.
Buy the Sony SRS-XB100. It is rated higher for sound quality than the Noxgear 0.1 lbs (39 g) and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
