Short answer: the Soundcore Select 4 Go. It ranks #25 of 62 small speakers by sound quality (rated 3.3/5) at $22.99 and is still sold new; the Harman Kardon Neo ranks #58 (rated 2.3/5) and is discontinued, so it is only an option used.
The Soundcore Select 4 Go is the better-sounding, longer-running choice. Quite inexpensive for what you get. It is rated for 20 hours of battery against 10 for the Harman Kardon Neo. It is rated IP67, while the Harman Kardon Neo has no water resistance. It has an adjustable EQ, which the Harman Kardon Neo lacks. The tradeoff: Not as deep of bass as higher ranked speakers.
The case for the Harman Kardon Neo: Harman Kardon Neo uses 1.6” (41mm) full-range driver. The tradeoff: Bass is limited by its 105Hz specification.
Buy the Soundcore Select 4 Go. It is rated higher for sound quality; the Harman Kardon Neo is no longer sold new.
