Short answer: the Soundcore Select 4 Go. It ranks #25 of 62 small speakers by sound quality, rated 3.3/5, at $22.99; 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 Soundcore Select 4 Go is the better-sounding, longer-running pick. A very inexpensive waterproof mini speaker with a strap, a long battery, app EQ, and stereo pairing. It is rated for 20 hours of battery against 15 for the Noxgear 0.1 lbs (39 g). It has an adjustable EQ, which the Noxgear 0.1 lbs (39 g) lacks. Watch for: Not as deep of 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 Soundcore Select 4 Go at 0.6 lbs (265 g). Watch for: It sounds worse than a clock radio with the worst bass of any speaker.
Buy the Soundcore Select 4 Go. It is rated higher for sound quality than the Noxgear 0.1 lbs (39 g) and costs less, so only choose the other one for a particular feature it does better.
