Short answer: the Bogasing G4. It ranks #27 of 179 medium speakers by sound quality, rated 4.0/5, at $42.49; the Bose Soundlink Revolve+ II ranks #50, rated 3.6/5, and costs $299, so there is little reason to consider the other one.
The Bogasing G4 is the better-sounding, longer-running pick. A light, affordable waterproof speaker with surprisingly strong bass for its size, solid loudness, long battery life and stereo pairing. It is rated for 24 hours of battery against 17 for the Bose Soundlink Revolve+ II. It is rated IPX7 against IP55 for the Bose Soundlink Revolve+ II. It plays in stereo from a single unit, unlike the Bose Soundlink Revolve+ II. The catch: The upper treble is boosted and uneven, while the mids sit slightly behind the bass and highs, so it is not a neutral choice for vocal-focused music.
What the Bose Soundlink Revolve+ II does well: A premium 360 degree speaker that sounds the same from any spot around it, with a carry handle and long battery life. The catch: Overly boosted bass, warm sounding.
Buy the Bogasing G4. It is rated higher for sound quality than the Bose Soundlink Revolve+ II and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
