Short answer: the Minirig Mini 2 if sound quality matters most, the Soundcore Select 4 Go if price matters most. The Minirig Mini 2 ranks #3 of 62 small speakers, rated 4.4/5, at $100. The Soundcore Select 4 Go ranks #25, rated 3.3/5, at $22.99, $77.01 cheaper.
The Minirig Mini 2 is the better-sounding pick. A tiny, very neutral speaker with much deeper bass than most its size, a long battery, and an optional add on subwoofer. It supports aptX Bluetooth, which the Soundcore Select 4 Go lacks. It keeps a wired aux input, which the Soundcore Select 4 Go lacks. The tradeoff: Calls itself splash resistant and has no official water rating.
The Soundcore Select 4 Go is the longer-running, tougher 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 12 for the Minirig Mini 2. It is rated IP67 against Splash resistant for the Minirig Mini 2. The catch: Not as deep of bass as higher ranked speakers.
