Short answer: the Soundcore Select 4 Go. It ranks #23 of 47 small speakers by sound quality at $22.99; the Harman Kardon Esquire Mini 2 ranks #42 and costs $100, so there is little reason to consider the other one.
What the Soundcore Select 4 Go offers: Quite inexpensive for what you get Watch for: 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.
What the Harman Kardon Esquire Mini 2 offers: Doubles as a hands-free speakerphone and USB power bank. Metal grille with a faux-leather back and a small kickstand. 8-10 hour battery life. Watch for: Huge lack of bass. Sounds very thin and tinny at high volume
Buy the Soundcore Select 4 Go. It ranks higher for sound quality than the Harman Kardon Esquire Mini 2 and costs less, which settles it without a real tradeoff to make.
The Harman Kardon Esquire Mini 2 is not a sound-quality pick. It sits near the bottom of the 47 small speakers; there are better options higher up.
If battery life is a priority, the Soundcore Select 4 Go is rated for 20 hours versus 10 hours for the Harman Kardon Esquire Mini 2.
If water resistance matters to you, the Soundcore Select 4 Go at IP67 (brief submersion) holds up far better than the Harman Kardon Esquire Mini 2 at no water resistance.
