Short answer: the Soundcore Select 4 Go, if you are buying new. The Teufel Boomster Go ranks higher than it (#7 vs #24 of 50 small speakers, 4.2/5 vs 3.3/5) but is discontinued, so only consider it used; the Soundcore Select 4 Go is still sold new at $22.99.
Buy the Soundcore Select 4 Go, since the Teufel Boomster Go is discontinued and only worth hunting down used.

Soundcore Select 4 Go: $22.99 Amazon AliExpress B&H Photo Video eBay
Pros: Quite inexpensive for what you get
Cons: Not as deep of bass as higher ranked speakers. Doesn’t get very loud before sound quality drops; some sibilance on snare/stick transients. No built-in mic; playback is mono unless you buy a second unit.
