Short answer: the Soundcore Select 4 Go. It ranks #25 of 62 small speakers by sound quality, rated 3.3/5, at $21.99; the Monster Cube 1 ranks #40, rated 3.0/5, and costs $29.99, so there is little reason to consider the other one.
The Monster Cube 1 is the lighter option. Rated for 20 hours of playback, far longer than the JBL Go 4, with IP68 dust and water protection, Bluetooth 6.0, a party mode that links up to 100 speakers, stereo pairing with a second unit and a microSD slot for playing music without a phone. At 0.4 lbs (200 g) it weighs noticeably less than the Soundcore Select 4 Go at 0.6 lbs (265 g). It links with other speakers (up to 100 speakers), which the Soundcore Select 4 Go cannot. The tradeoff: No measurements, so its rating is estimated from side-by-side listening tests.
Why pick the Soundcore Select 4 Go: Quite inexpensive for what you get. It has an adjustable EQ, which the Monster Cube 1 lacks. The tradeoff: Not as deep of bass as higher ranked speakers.
Buy the Soundcore Select 4 Go. It is rated higher for sound quality than the Monster Cube 1 and costs less, so only choose the other one for a particular feature it does better.
Worth knowing: the Monster Cube 1 has not been measured yet. Its rating is estimated from related models, with a likely range of 2.7 to 3.3, so treat this verdict as provisional.

The Two Speakers In Full
Monster Cube 1: $29.99 Estimated eBay
Pros: Rated for 20 hours of playback, far longer than the JBL Go 4, with IP68 dust and water protection, Bluetooth 6.0, a party mode that links up to 100 speakers, stereo pairing with a second unit and a microSD slot for playing music without a phone.
Cons: No measurements, so its rating is estimated from side-by-side listening tests. Against the JBL Go 4 it plays louder with more bass but sounds less balanced and less clear. There is no app or EQ, and it is hard to buy in the US, where the official store lists it as sold out.
