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 Muzen Wild Go ranks #56, rated 2.4/5, and costs $45.99, so there is little reason to consider the other one.
The Soundcore Select 4 Go is the better-sounding, longer-running choice. 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 8 for the Muzen Wild Go. It is rated IP67 against IPX5 for the Muzen Wild Go. It has an adjustable EQ, which the Muzen Wild Go lacks. Watch for: Not as deep of bass as higher ranked speakers.
The Muzen Wild Go is the lighter pick. A small speaker with a vintage military radio look, a sturdy metal body, and a built in flashlight for camping trips. At 0.4 lbs (187 g) it weighs noticeably less than the Soundcore Select 4 Go at 0.6 lbs (265 g). The tradeoff: Not much bass at all, quite thuddy.
Buy the Soundcore Select 4 Go. It is rated higher for sound quality than the Muzen Wild Go and costs less, so only choose the other one for a particular feature it does better.
